The answer is A. 0.1x + 18.2
Step-by-step explanation:
We have to simplify the expression
We will use distributive Property of Multiplication with respect to Addition and Subtraction
⇒3×(2.7 x +5) -2 ×(4 x -1.6)
=3×2.7 x +3×5-2×4 x-2×(-1.6)
=8.1 x +15 -8 x+3.2
=(8.1 x- 8 x)+15+3.2-----Adding and Subtracting like terms

round to the nearest tenth, if needed.
Answer:
\(\pi\) or 3.1
Step-by-step explanation:
The total area of the circle is \(3^2\pi\). The central angle of the shaded region is 40 degrees so we have to multiply \(3^2\pi\) by \(\frac{40}{360}\) or \(\frac{1}{9}\). 3 squared is 9 so 9\(\pi\) times \(\frac{1}{9}\) is just equal to \(\pi\). \(\pi\)=3.14159265... rounded to the nearest tenth is 3.1

Rewrite as a simplified fraction.

Answer:
61/90
Step-by-step explanation:
Integrate :
\(\red{\footnotesize\displaystyle\bf \int cos^3 4x\:\:dx}\)
Recall the half-angle identity for cosine:
cos²(x) = 1/2 (1 + cos(2x))
Then we can rewrite the integrand as
cos³(4x) = cos(4x) cos²(4x) = 1/2 cos(4x) (1 + cos(8x))
So we have
\(\displaystyle \int \cos^3(4x) \, dx = \frac12 \int (\cos(4x) + \cos(4x)\cos(8x)) \, dx\)
Next, recall the cosine product identity,
cos(a) cos(b) = 1/2 (cos(a - b) + cos(a + b))
so that the integral is equivalent to
\(\displaystyle \int \cos^3(4x) \, dx = \frac12 \int \cos(4x) \, dx + \frac14 \int (\cos(4x - 8x) + \cos(4x + 8x)) \, dx\)
\(\displaystyle \int \cos^3(4x) \, dx = \frac34 \int \cos(4x) \, dx + \frac14 \int \cos(12x) \, dx\)
Computing the rest is trivial:
\(\displaystyle \int \cos^3(4x) \, dx = \boxed{\frac3{16} \sin(4x) + \frac1{48} \sin(4x) + C}\)

A roller coaster has a mass of 300 kg. It drops from rest at the top of a hill
that's 101 m tall. How fast is it going when it reaches the bottom?
Acceleration due to gravity is g = 9.8 m/s2.
A. 76.7 m/s
B. 44.5 m/s
C. 41.2 m/s
D. 21.8 m/s
Answer:
To determine the velocity of the roller coaster as it moves down, we use the kinematic equation which is expressed as 2gy = vf^2 - v0^2 where g is the gravitational acceleration, y is the elevation of the roller coaster, vf and vo are the final and initial velocity. We calculate as follows:
2gy = vf^2 - v0^2
Since it starts at rest, v0 is zero.
2gy = vf^2
vf = √2gy
vf = √2(9.8)(101)
vf = 44.5 m/s ----> option B

Evaluate the definite integral of sin^5(x)dx from 0 to pi/2.
Step-by-step explanation:
The definite integral of sin^5(x)dx from 0 to pi/2 can be evaluated using the method of substitution.
Let u = sin(x), then du = cos(x)dx
The integral becomes:
∫sin^5(x)dx = ∫u^5du from 0 to sin(π/2)
= (u^6)/6 evaluated at sin(π/2) and 0
= (sin^6(π/2))/6 - 0
= (1^6)/6
= 1/6
So, the definite integral of sin^5(x)dx from 0 to pi/2 is equal to 1/6.
5. Alan and Alice play a game of noughts and crosses. From looking at previous games,
the probability of Alan winning is 0.31, the probability Alice will win is 0.45. What is
the probability of a draw?
Answer:
0.24
Step-by-step explanation:
Then the probability of a draw = 1- (p
Pr(Alan) = the probability of Alan winning = 0.31,
Pr(Alice) = the probability Alice will win = 0.45.
We are required to give probability of a draw.
= 1-(pr(alan) + pr(alice)
= 1-0.45+0.31
= 1 - 0.76
= 0.24
We have 24% probability of having a draw.

Algebraic expression for 4less then 3x
When 'x' is 5, the Algebraic expression 3x - 4 evaluates to 11.
To find the algebraic expression for "4 less than the product of 3 and some number," let's break it down step by step.
First, let's define the unknown number as 'x.' Since the problem states "the product of 3 and some number," we can express this as 3 * x or simply 3x.
Next, we want to subtract 4 from this product. The phrase "4 less than" indicates subtraction, so we subtract 4 from 3x. This can be represented as 3x - 4.
In summary, the algebraic expression for "4 less than the product of 3 and some number" is 3x - 4, where 'x' represents the unknown number.
To calculate the value of this expression for a specific value of 'x,' you substitute that value into the expression and simplify. For example, if 'x' is 5, you would substitute 5 into the expression:
3(5) - 4
This simplifies to:
15 - 4 = 11
So, when 'x' is 5, the expression 3x - 4 evaluates to 11.
In general, the algebraic expression allows us to represent a mathematical relationship between quantities using symbols and operations. By substituting specific values into the expression, we can calculate the corresponding results.

Which equation describes the link passing through points (-5,-1) and (5,5) ?
Answer:
5x-4y=4 there hope this helps had the same problem
Answer: Choice D
y = (3/5)x + 2
==================================
Explanation:
Find the slope
m = (y2-x1)/(x2-x1)
m = (5-(-1))/(5-(-5))
m = (5+1)/(5+5)
m = 6/10
m = 3/5
Now use point slope form and solve for y
y - y1 = m(x - x1)
y - (-1) = (3/5)(x - (-5))
y + 1 = (3/5)(x + 5)
y + 1 = (3/5)x + (3/5)*5
y+1 = (3/5)x + 3
y = (3/5)x + 3 - 1
y = (3/5)x + 2

The scale is 1:40, meaning that if the house plan shows 1 of something, the real life version is 40 times larger. Given this information:
4.5 m by 6.3 m is the ACTUAL SIZE.
Given this, we need to divide by 40 to get the room PLAN.
