The image of the point (4. 9) under a translation is (9. 13). Find the coordinates
of the image of the point ( 5. 2) ander the same translation,
Answer:
The coordinates of the image are (10,6)
Step-by-step explanation:
Translation
A point located at (x,y), translated by (a,b) maps to the point (x+a,y+b).
If we know the location of the point (x,y) and the location of its image (x',y'), we can know the values of (a,b) by subtracting:
(a,b) = (x',y') - (x,y)
We know the coordinates of the point (4,9) and the coordinates of its image (9,13). Calculate the translation:
(a,b) = (9,13) - (4,9) = (5,4)
If the point (5,2) is translated under the same conditions, then it will map to the point (5,2) + (5,4) = (10,6).
The coordinates of the image are (10,6)
Reflect (-4, -7) across the x axis. Then reflect the results across the x axis again. What are the coordinates of the final point?
The final point after reflecting (-4, -7) twice across the x-axis is (-4, 7).To reflect a point across the x-axis, we change the sign of its y-coordinate while keeping the x-coordinate the same.
Given the initial point (-4, -7), let's perform the first reflection across the x-axis. By changing the sign of the y-coordinate, we get (-4, 7). Now, to perform the second reflection across the x-axis, we once again change the sign of the y-coordinate. In this case, the y-coordinate of the previously reflected point (-4, 7) is already positive, so changing its sign results in (-4, -7). Therefore, after reflecting the point (-4, -7) across the x-axis twice, the final point is (-4, 7). The reflection process can be visualized as flipping the point across the x-axis. Initially, the point (-4, -7) lies below the x-axis. The first reflection across the x-axis brings it to the upper side of the x-axis, resulting in (-4, 7). The second reflection flips it back down below the x-axis, yielding the final point (-4, -7).It's worth noting that reflecting a point across the x-axis twice essentially cancels out the reflections, resulting in the point returning to its original position. In this case, the original point (-4, -7) and the final point (-4, -7) have the same coordinates, indicating that the double reflection has brought the point back to its starting location.

Answer:
Measure of arc TSU = 201°
Step-by-step explanation:
For the inscribed circle of triangle XYZ, we have;
∠XZY = 21°
Segment TZ and segment UZ are tangent to circle R
Therefore, ∠ZUR = ∠ZTR = 90° (angle formed by a tangent)
Length UR = Length TR = Radius of circle R
∴ ΔZTR ≅ ΔZUR Side Angle Side (SAS) rule of Congruency
∴ ∠RZT ≅ ∠RZU, (Congruent Parts of Congruent Triangles are Congruent, CPCTC)
∠XZY = ∠RZT + ∠RZU (Angle summation)
21° = ∠RZT + ∠RZU = 2×∠RZU (Transitive property)
∠RZU = 21°/2 = 10.5° = ∠RZT
∴ ∠URZ = 180- 90 - 10.5 = 79.5° = ∠TRZ (CPCTC)
arc TU = ∠URT = ∠URZ + ∠TRZ = 79.5 + 79.5 = 159° (angle addition)
∴ Measure of arc TSU = 360° - 159° = 201° (Sum of angles at the center of the circle R)
Measure of arc TSU = 201°.

Solve the initial value problem. y'(t) = 1 + e^t, y(0) = 20 The specific solution is y(t)= _____ .
The initial value problem. y'(t) = 1 + e^t, y(0) = 20 The specific solution is y(t)= t + e^t + 19.
Let's go step-by-step:
1. Identify the problem: We are given a differential equation y'(t) = 1 + e^t and an initial value y(0) = 20.
2. Integrate the differential equation: To find y(t), we need to integrate the given equation with respect to t.
∫(y'(t) dt) = ∫(1 + e^t dt)
3. Perform the integration: After integrating, we obtain the general solution of the problem:
y(t) = t + e^t + C, where C is the constant of integration.
4. Apply the initial value: We are given y(0) = 20, so we can plug this into the general solution to find the specific solution.
20 = 0 + e^0 + C
20 = 1 + C
5. Solve for the constant of integration C: From the above equation, we find the value of C.
C = 19
6. Write the specific solution: Now that we have the value of C, we can write the specific solution for y(t).
y(t) = t + e^t + 19
So, the specific solution for this initial value problem is y(t) = t + e^t + 19.

a jet travels 2544 miles against the wind in 4 hours and 3184 miles with the wind in the same amount of time. what is the rate of the jet in still air and what is the rate of the wind?
Rate of the jet in still Air is 716 miles per hour and
wind speed is 80 miles/hour.
What is relative velocity?The velocity of an item in relation to another observer is known as its relative velocity. It is the pace at which one item's relative location changes in relation to another object over time. When two bodies are travelling in opposing directions, their relative velocity is at its highest. They are approaching one another.
Let ‘X’ be speed of jet and
'Y’ be speed of Wind
Relative velocity when jet travels against wind: X - Y = ( 2544 / 4 ) = 636 miles/hour
Relative velocity when jet travels with wind is: X + Y = ( 3184 / 4 ) = 796 miles/hour
By adding these two equations we will get
2 X = 1432 or X = 716 miles /hour and
or, Y = 796 - 716 = 80 miles/hour
Hence,
Rate of the Jet in still Air is 716 miles per hour and
Wind speed is 80 miles/hour.

An inequality equation to determine the amount of money she will spend is x > 6
Mae wants to make more than 6 gift baskets for the school raffle. Each gift basket costs $15.50. To determine the amount of money she will spend to make these gift baskets, we can write an inequality.
Let's assume that the number of gift baskets Mae wants to make is represented by the variable "x". The inequality can be written as follows: 15.50x > 6 * 15.50.
This inequality equation states that the total cost of the gift baskets, which is represented by 15.50 times the number of gift baskets (x), must be greater than the cost of 6 gift baskets (6 * 15.50).
Alternatively, we can rewrite the inequality as 15.50x > 93, which states that the total cost of the gift baskets must be greater than $93 if Mae wants to make more than 6 gift baskets.
Finally, we can simplify the inequality to x > 6, which states that the number of gift baskets Mae wants to make must be greater than 6 in order for her to spend more than $93 on the gift baskets.

air is blown into a spherical balloon so that, when its radius is 5.20 cm, its radius is increasing at the rate 0.840 cm/s. (a) find the rate at which the volume of the balloon is increasing. cm3/s (b) if this volume flow rate of air entering the balloon is constant, at what rate will the radius be increasing when the radius is 13.90 cm? cm/s (c) explain physically why the answer to part (b) is larger or smaller than 0.840 cm/s, if it is different.
The rate of increase in the radius is larger because, as the radius increases, the rate of change in the volume increases as well.
(a) The rate at which the volume of the balloon is increasing can be found by using the formula for the volume of a sphere: V = (4/3)πr3. Differentiating this with respect to time gives the rate at which the volume is increasing: dV/dt = 4πr2(dr/dt). When r = 5.20 cm and dr/dt = 0.840 cm/s, the rate at which the volume is increasing is 4π(5.20 cm)2(0.840 cm/s) = 4.15 cm3/s.
(b) When the radius is 13.90 cm, the rate at which the volume is increasing is 4π(13.90 cm)2(dr/dt). For this rate to remain constant, dr/dt must increase. Thus, the rate at which the radius is increasing must be larger than 0.840 cm/s.
(c) Physically, this is because the rate of change in the volume of the balloon increases as the radius increases. As the radius increases, the surface area of the balloon increases, allowing more air to enter the balloon. Thus, in order to maintain a constant volume rate, the rate of increase in the radius must also increase.

Griffith's criteria for fast fracture in an ideal brittle material provide a framework for assessing the conditions necessary for rapid fracture. This theory is only applicable to brittle materials and assumes sharp, circumferential cracks with a small radius compared to the crack length.
By calculating the critical crack length using the formula σ = KIc/√(πa), we can determine the crack length required for propagation. In the example provided, the critical crack length for a nickel alloy is larger (1.73 × 10−6 m) compared to Sic ceramic (2.31 × 10−8 m). This implies that the nickel alloy can withstand more damage before fracturing, making it more suitable for applications such as compressor blades in jet engines.
