Step-by-step explanation:
[tex]f(x)=2x+5 \\\\ g(x)=x^2 \\\\h(x)=-2x[/tex]
[tex]h(g(f(x)))=-2((2x+5)^2)[/tex]
Expanding and solving for brackets.

Distributing -2 to the terms in the brackets.
[tex]h(g(f(x)))=-8x^2-40x-50[/tex]
Answer:
-8x^2 - 40x - 50
Step-by-step explanation:
f(x) = 2x + 5
g(x) = x^2
h(x) = -2x
h(g(f(x))) =
First find g(f(x))
g(f(x)) = (2x+5) ^2 = 4x^2 + 10x + 10x +25
= 4x^2 + 20x + 25
The stick this in for g(f(x)
h(g(f(x))) = -2 (4x^2 + 20x + 25)
= -8x^2 - 40x - 50
SALES A daily newspaper had 12,125 subscribers when it began publication. Five years later it had 10,100 subscribers. What is the average yearly rate of change in the number of subscribers for the five-year period?
Answer:
The average change is 405
Step-by-step explanation:
The initially the number of subscriber = 12125
After five years the number of subscriber = 10100
Now we have to find the average change in the number of subscribers.
The average yearly change = change in subscriber/number of years.
Now insert the values in the above formula.
The average yearly change = (12125 – 10100) / 5
The average yearly change = 2025/5
The average yearly change = 405
Answer: The average change is -405

Answer:
[tex]7+(11-4\times 2)=10[/tex]
Step-by-step explanation:
So, this question involves you to play around with the numbers and the operations a bit. I've come up with a solution, but perhaps there are others as well.
So, we have:
[tex]7\text{ } 11\text{ } 4\text{ } 2\text{ } =\text{ } 10[/tex]
So, what we can do is, for instance, multiply 4 and 2. Subtract that into 11. And then add the difference to 7. Thus:
[tex]7+(11-4\times 2)=10[/tex]
This is a true number sentence. Let's do it to make sure.
First, do the operations inside the parentheses.
Multiplication comes first, so multiply:
[tex]7+(11-8)=10[/tex]
Again, do the parentheses first. Subtract:
[tex]7+(3)=10[/tex]
Now add:
[tex]10=10[/tex]
So our answer is correct :)

Solve for y. 6y=y+25
Answer:
6y =y+25
6y-y=25
5y=25
y=25/5
y=5
hope that helps: )
Answer:
y = 5
Step-by-step explanation:
[tex]6y=y+25[/tex]
Subtract y from both sides ;
[tex]6y-y=y+25-y[/tex]
Simplify ;
6y - y = 5y
y -y =0
[tex]5y=25[/tex]
Divide both sides by 5
[tex]\frac{5y}{5}=\frac{25}{5}[/tex]
Simplify
[tex]y =5[/tex]
Find the area of the base B of the solid.

Step-by-step explanation:
v=[tex]\pi[/tex]r²h
84[tex]\pi[/tex]=
84[tex]\pi[/tex]÷7
12=r²
area of a circle is [tex]\pi[/tex]r²
so B is 12[tex]\pi[/tex]in²
The area of the base of the cylinder in the image given will be 12pi in.
How to Find the Base Area of a Cylinder?The formula for the volume of a cylinder = πr²h, where:
Base area of the cylinder (B) = πr²
(r is the radius)
The Height of the cylinder = h
The given cylinder has the following,
Height of cylinder (h) = 7 in.
Volume of cylinder = 84pi in.³
Then Substitute into the volume formula:
(πr²)7 = 84pi
(B)7 = 84pi (B = area of the base)
Divide both sides by 7;
(πr²)7/7 = 84pi /7
B = 12pi
Therefore, the area of the base of the cylinder in the image given will be 12pi in.

In the past year Pablo watched 76 movies that he thought were very good he watched 80 movies over the whole year of the movies he watched what percentage did he rate as very good
Answer:
95%
Step-by-step explanation:
We convert 80 into ten or 100. In this case, we should use 10.
76/80 = 9.5/10
Then we set the denominator as 100. (because percentages have a denominator as 100)
95/100
Then it's 95%. Hope this helps.

what is the square root of 169/196
Answer:
sqrt 169 is 13
sqrt 196 is 14
Step-by-step explanation:
The square root of the number in the fractional form [tex]\frac{169}{196}[/tex] is the number in fractional form [tex]\frac{13}{14}[/tex].
Given a number:
[tex]\frac{169}{196}[/tex]
It is required to find the square root of the number.
The square root of the fraction can be found by taking the square root of each component and dividing it.
That is:
[tex]\sqrt{\frac{x}{y} } =\frac{\sqrt{x} }{\sqrt{y} }[/tex]
Here, x = 169 and y = 196.
So, this can be written as:
[tex]\sqrt{\frac{169}{196} } =\frac{\sqrt{169} }{\sqrt{196} }[/tex]
[tex]=\frac{13}{14}[/tex]

The density of a certain material is such that it weighs 6 pounds per pint of volume. Express this density in grams per liter. Round your answer to the nearest whole number.
Answer:
Density = 4779 grams per liter
Step-by-step explanation:
here we need to convert
pounds to gram
pint to liter
1 pound = 454 grams
1 pint = 0.57 liters
given
density = 6 pounds per pint
now using grams in place of pound and
liter in place of pint we have
density = 6 pounds per pint = 6*454 grams /0.57 liters
density = 2724 pounds/ 0.57 liters = 4778.94 grams / liters
Density when rounded to nearest whole number is 4779 grams / liters
Robot 1 is at Asteroid U. Calculate the distance between U (38,22) and W (55,30) to the nearest thousandths, then add a driveDistance block to drive the robot to Asteroid W.
Answer:
When we have two vectors:
A = (a1, a2)
B = (b1, b2)
The distance between these two vectors is:
D = √( (a1 - b1)^2 + (a2 - b2)^2)
In this case, the vectors are:
U = (38, 22) and W = (55, 30)
The distance between U and W is:
D = √( (38 - 55)^2 + (22 - 30)^2 )
D = √( 289 + 64) = √353 = 18.7882
We want to round it to the nearest thousandths (the third digit to the right of the decimal point).
Then we must look at the next one (the fourth)
if the fourth digit is 5 or smaller, we round down
if the fourth digit is larger than 5, we round up.
We can see that in 18.7882 the fourth digit after the decimal point is a 2, so we round down, then the distance between U and W is:
D = 18.788
Now i guess that you want a line that connects U with W so the robot can follow it,
To find the line you can use a linear relation:
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
So we want a line that passes through the points U and W, the slope of this line will be:
a = (30 - 22)/(55 - 38) = 0.47
Then the equation is:
y = 0.47*x + b
to find the value of b, we know that this line passes through the point (38,22) then:
y = 22 = 0.47*38 + b
b = 22 - 0.37*38 = 7.94
The line that can use the robot to go from U to W is:
y = 0.47*x + 7.94
q1: How can you rewrite -8 -− 10 as an additional problem? q2: Find the difference: -11 -− 5
Answer:
1. 2
2. -6
Step-by-step explanation:
I guess you tried to write -8-(-10) in the first question. Minus sign cancels out minus sign to give addition sign. So that is -8+10 which is 2.
The second question the sam thing applies -11-(-5) which is -11+5 which is -6

n =4/5(m+7); m
Answer:
[tex]m = \frac{5n}{4} - 7[/tex]Step-by-step explanation:
[tex]n = \frac{4}{5} (m + 7)[/tex]First of all multiply both sides by 5
That's
[tex]5n = 5 \times \frac{4}{5} (m + 7) \\ 5n = 4(m + 7)[/tex]Next divide both sides by 4
That's
[tex]m + 7 = \frac{5n}{4} [/tex]
Subtract 7 from both sides to make m stand alone
We have
[tex]m + 7 - 7 = \frac{5n}{4} - 7[/tex]We have the final answer as
