PLEASE ANSWER QUICK On a number line, a segment has an endpoint at -1 and a midpoint at 2.75. What is the other endpoint? Enter your answer in decimal form.

Answer:

Guido tiene 9 años, Andrés tiene 36 años y David tiene 3 años.

Step-by-step explanation:

Con la información proporcionada, sabes que la edad de los tres suma 48, lo que se puede expresar como:

x+y+z=48, donde:

x es la edad de Guido

y es la edad de Andrés

z es la edad de David

Además, de acuerdo al enunciado puedes decir que la edad del papá Andrés es cuatro veces la edad de Guido y que la edad de David es la tercera parte de la edad de Guido y puedes escribir las siguientes ecuaciones:

y=4x

z=x/3

Ahora puedes reemplazar estas dos ecuaciones en la primera y despejar x:

x+4x+x/3=48

5x+x/3=48

16x/3=48

16x=48*3

16x=144

x=144/16

x=9

Después, puedes reemplazar el valor de x en y=4x para encontrar el valor de y:

y=4x

y=4*(9)

y=36

Finalmente, debes reemplazar el valor de x en z=x/3 para encontrar el valor de z:

z=x/3

z=9/3

z=3

De acuerdo a esto, Guido tiene 9 años, Andrés tiene 36 años y David tiene 3 años.

When Emma saves each month for a goal, the value of the goal called is referred to as (B) future value.

An annuity is a stream of equal payments received or paid at equal intervals of time. Annuity value represents the present value of the annuity amount that will be received at the end of the specified time period. Future value (FV) is the value of an investment after a specified period of time. It is the value of the initial deposit plus the interest earned on that deposit over time. The future value of a single deposit will increase over time due to the effect of compounding interest.

When Emma saves each month for a goal, the amount she saves accumulates over time and earns interest. The future value is calculated based on the initial deposit amount, the number of months it will earn interest, and the interest rate. It is important to determine the future value of the goal in order to make effective financial decisions that will enable Emma to achieve her goal.

Answer:

H = 7mm

Step-by-step explanation:

Height of Prism

So to calculate the height, multiply L · H · W. But since there is no height we will multiply what is given and then divide the volume by the product. For this case, the volume of the prism is 840 and its length is 10 and its width is 12. Multiply 10 and 12 then dividing 840 by 120. The height of the prism is 7.

Solve

Volume if the rectangular prism is given by the formula

                                             V = L · H · W

Length, Height, Width of the prism

                          L = 10mm H = 12mm Volume = 840mm³

10 · 12 · h = 840

∴ 840 ÷ 120 = 7

H = 7mm

True. The Pearson correlation coefficient (r) measures the strength and direction of the linear relationship between two variables, such as x and y.

The regression equation is used to make predictions or estimate the value of one variable (dependent variable) based on the value of another variable (independent variable).

When the correlation coefficient (r) is higher (closer to 1 or -1), it indicates a stronger linear relationship between the variables. In this case, when r = 0.80, it suggests a stronger linear relationship between x and y compared to when r = 0.60.

A stronger linear relationship between the variables implies that the regression equation will produce more accurate predictions. This is because the relationship between the variables is better captured by the regression model when there is a stronger correlation. Therefore, when r = 0.80, the regression equation is expected to provide more accurate predictions compared to when r = 0.60.

Answer:

VOLUME = 125 cm ³

SURFACE AREA  = 125 cm ²

Step-by-step explanation:

Volume of cube is

V = s³, where s = 5 cm

V = ( 5 cm )³ = 125 cm³

Surface area of the cube is

SA = 6 * s², where s = 5 cm

SA = 6 * ( 5 cm )² = 6 * 25 cm² = 125 cm²

To evaluate the surface integral ∬S (x y z) · ds, we need to calculate the dot product between the vector function (x y z) and the surface element ds, and then integrate it over the surface S. The surface integral is -27.

The given parallelogram has parametric equations x = u v, y = u − v, and z = 1/2u v, with u ranging from 0 to 3 and v ranging from 0 to 2. To find the surface element ds, we take the cross product of the partial derivatives of the position vector r(u, v) = (u v, u - v, 1/2u v) with respect to u and v. The resulting cross product gives us the magnitude and direction of the surface element.

Taking the cross product, we get ds = |∂r/∂u × ∂r/∂v| du dv. Substituting the partial derivatives, we have ds = |v(1/2v, 1, u/2) - (1/2uv, -1, v/2)| du dv.

Next, we calculate the vector function (x y z) · ds. Substituting the given parametric equations, we have (x y z) = (u v, u - v, 1/2u v), and the dot product becomes (u v)(u - v)(1/2u v) · ds.

By substituting the surface element ds, we have (u v)(u - v)(1/2u v) · |v(1/2v, 1, u/2) - (1/2uv, -1, v/2)| du dv.

To evaluate the surface integral, we integrate the dot product (u v)(u - v)(1/2u v) · |v(1/2v, 1, u/2) - (1/2uv, -1, v/2)| over the given limits of u and v. The resulting value will give us the surface integral of the vector function (x y z) over the parallelogram.

After evaluating this integral using a mathematical software or by hand calculation we get that the surface integral is equal to -27.

Answer:

x = 5 - y/3

Step-by-step explanation:

Using the equation of a circle, it is found that the value of y is -4.

Equation of the circle:

A circle is a closed curve that is drawn from the fixed point called the center, in which all the points on the curve are having the same distance from the center point of the center.

The equation of a circle with (h, k) center and r radius is given by:

(x-h)² + (y-k)² = r²

Given,

The points (0, 5) and (0, −5) are the endpoints of the diameter of a circle.

The point (3, y) is on the circle, in quadrant 4.

Here we need to find the value of y.

The center is the midpoint of them, thus:

\(x=\frac{0+0}{2}=0\\ y=\frac{5-5}{2}=0\)

So, the midpoint is (0,0).

The diameter(twice the radius) is the distance between these two points, so:

\(2r=\sqrt{(0-0)^2+(5-(-5))^2}\)

=> 2r = √0+100

=> 2r = √100

=> 2r = 10

=> r = 5

Thus, the equation of the circle is:

=> x² + y² = r²

Apply the values,

=> x² + y² = 5²

=> x² + y² = 25

The point (3,y) is on the circle, in quadrant 4. This means that:

Replacing x by 3, we can find the value of y.

Quadrant 4 means that y < 0.

Then:

=> 3² + y² = 25

=> y² = 25 - 9

=> y² = 16

=> y = ±√16

=> y = - 4

The value of y is -4.

The set of free variables found in the expression (λx.λy.y (λz.x)) (λx.z) is { } (the empty set).

To find the set of free variables in the given lambda calculus expression, we need to identify all variables that are not bound by any lambda abstraction.

Starting from the innermost expression (λx.z), we see that x is bound by the lambda abstraction, so x is not a free variable. Moving outward to the next expression (λy.y (λz.x)), we see that y is also bound by the lambda abstraction, so y is not a free variable. Finally, we reach the outermost expression (λx.λy.y (λz.x)), where the only occurrence of x is bound by the lambda abstraction.

Since there are no variables in the expression that are not bound by any lambda abstraction, the set of free variables is { } (the empty set).

The transformation from function f(x) to g(x) is a vertical shift of 4 units up.

The transformation from f(x) to g(x) is a vertical shift of 4 units up. This can be seen by comparing

f(x) = |x| to g(x) = |x| + 4

. In other words, the graph of g(x) is 4 units higher than that of f(x), and the x-intercepts of the two functions are 4 units apart.

The transformation from f(x) to g(x) is a vertical shift of 4 units up. This can be seen by comparing the equations of the two functions. The parent function, f(x), is defined as f(x) = |x|, and the transformed function, g(x), is defined as g(x) = |x| + 4. By adding 4 to the parent function, the graph of the transformed function is shifted up 4 units, which is the same as saying it is shifted 4 units in the positive y-direction. This can be seen in the graphs of the two functions, where the x-intercepts of the two functions are 4 units apart.

Answer:

Step-by-step explanation:

To find the exact values of trigonometric functions for the given conditions of 3π < t < 7π and tan(t) = 12² ar, we can use the given information to determine the values of sine, cosine, secant, cosecant, and cotangent.

Since tan(t) = 12² ar, we can deduce that tan(t) = 144. Using the Pythagorean identity, we can find the values of **sine** and **cosine**.

sin(t) = √(1 / (1 + tan²(t))) = √(1 / (1 + 144²)) = √(1 / (1 + 20736)) = √(1 / 20737)

cos(t) = tan(t) * sin(t) = 144 * √(1 / 20737)

To find the values of secant, cosecant, and cotangent, we can use the reciprocal identities:

**sec(t) = 1 / cos(t) = 1 / (144 * √(1 / 20737))**

csc(t) = 1 / sin(t) = 1 / √(1 / 20737)

cot(t) = 1 / tan(t) = 1 / 144

Therefore, the exact values of the trigonometric functions are as follows:

sint = √(1 / 20737)

cost = 144 * √(1 / 20737)

sect = 1 / (144 * √(1 / 20737))

csct = 1 / √(1 / 20737)

cott = 1 / 144
