Answer:
Option C, 20 is the answer.
Step-by-step explanation:
Let g(x) = 2x and h(x) = x² + 4
We have to evaluate (h ο g) ( -2 )
Since ( h ο g )x = h [ g(x) ]
= ( 2x)² + 4
= 4x² + 4
( h ο g ) ( -2 ) = 4 ( -2 )² + 4
= 4 × 4 + 4
= 16 + 4
= 20

compound inequality for the following scenario:
The scores on the last test ranged from 71% to 95%
Hurry up please
Answer: [tex]0.71 \le x \le 0.95[/tex]
Work Shown:
71% = 71/100 = 0.71
95% = 95/100 = 0.95
x represents the possible values of the scores. The compound inequality above shows that x is between 0.71 and 0.95, including both endpoints. Note the use of "or equal to" as part of each inequality sign.
*Suppose you drop a tennis ball from a height of 15 feet. After the ball hits the floor, it rebounds to 12 feet, then hits the floor and rebounds to 9.6 feet.
Write an explicit formula for the sequence.
Also, How high will the ball rebound after its fourth bounce?
Answer:
The explicit formula is [tex]a_n=15(\frac{4}{5})^{n-1}[/tex].
Step-by-step explanation:
First, we need to find the common ratio. We know this is a geometric sequence because the decrease from one term to the next is not a constant number.
To find the constant ratio, we can take the [tex]2^{nd}[/tex] term and divide by the [tex]1^{st}[/tex] term:
[tex]\frac{2nd}{1st}=\frac{12}{15}=\frac{4}{5}[/tex]
So, our common ratio is [tex]r=\frac{4}{5}[/tex].
We already know our initial term, [tex]a_0[/tex] is 15, so we get:
[tex]a_n=a_0(r)^{n-1}\\a_n=15(\frac{4}{5})^{n-1}[/tex]

Area = 6 + 28 + 16 + 18 + 15 + 12 + 6 + 21
Area = 122 square yards.
The quantity of paint required will be calculated as,

Answer:
ok so first we have to find the total amount
4*5=20
5*2=10
10*3=30
24*1=24
0*3=0
now lets add up the total

one number is three times another number, and their sum is -10. what is the smaller of the two numbers?
Let the smaller number be x .
Then the larger number = 3x
Their sum = -10
This can be written in an equation as :-
[tex]x + 3x = - 10[/tex]
[tex]4x = - 10[/tex]
[tex]x = \frac{ - 10}{ \: \: \: 4} [/tex]
[tex]x = - 2.5[/tex]
Which means :-
The value of the first number = -2.5
The value of the second number = -2.5 × 3 = -7.5
Therefore , the smaller of the two numbers is = -7.5
Answer:
let a + b = -10
where a = 3b
substitute a into the equation: a + b = -10
3b + b = -10
b = -10 / 4
b = -2.5
a = 3b
a = 3(-2.5)
a = -7.5
check:
a + b = -10
-7.5 + (-2.5) = 10
-10 = 10

Find the equation of the tangent line to the curve y= 2x2 + x-1 at the point (5, 54).
Answer: y-54=21(x-5) or y=21x-51
Step-by-step explanation:
To find the equation of the tangent line, we first want to find the derivative of the equation.
f(x)=2x²+x-1 [Power Rule]
f'(x)=4x+1
Now that we have the derivative, we use (5,54) to find the slope.
f'(5)=4(5)+1 [multiply]
f'(5)=20+1 [add]
f'(5)=21
With our slope, we can plug it into point-slope form.
y-54=21(x-5)
We can also convert this to slope-intercept form.
y-54=21(x-5) [distribute]
y-54=21x-105 [add both sides by 54]
y=21x-51
Now, we know the tangent line is y-54=21(x-5) or y=21x-51.

[tex]\huge\boxed{Thanks,\;Plip.}[/tex]
We want to find and solve an equation that tells us the number of pounds of raisins that we need to add to a mixture to get to a desired price.
We will see that we need to add 3 pounds of raisins.
We know that:
Granola costs $3.25 per lbRaisins cost $6.50 per lb.If we mix M pounds of raisins with 10 pounds of granola, the total mass will be:
M + 10
The price of this will be:
M*$6.50 + (10)*$3.25
And we want the price of this mixture to e $4.00 per pound, then we have:
M*$6.50 + (10)*$3.25 = (M + 10)*$4.00
Now we need to solve the above equation for M.
M*$6.50 + $32.50 = M*$4.00 + $40.00
M*$6.50 - M*$4.00 = $40.00 - $32.50
M*($6.50 - $4.00) = $7.50
M*$2.50 = $7.50
M = ($7.50)/($2.50) = 3
M = 3
This means that we need to add 3 pounds of raisins.

Please help
The volume of the rectangular prism is the amount of space in the prism
The volume of the rectangular prism is x^3+8x^2+19x+12 cubic inches
How to determine the volume?The given parameters are:
Base area = x^2+5x+4
Height = x + 3
The volume is then calculated as:
Volume = Base area * Height
So, we have:
Volume = (x^2+5x+4) * (x + 3)
Expand
Volume = x^3+5x^2+4x + 3x^2+15x+12
Collect like terms
Volume = x^3+5x^2+ 3x^2+4x +15x+12
Evaluate the sum
Volume = x^3+8x^2+19x+12

(A) 3 (B) 4 (C) 12 (D) 36
Answer:
(D) 36
Step-by-step explanation:
0.5% = 0.5/100 = 0.005
It is given that the population (215) is predicted to increase by 0.5%. To know the value after increment, 215 has to be multiplied by (1 + 0.005) or 1.005.
In the equation P = 215(1.005)t/3, the value of t/3 has to be equal to 1 for 0.5% increase.
t/3 = 1
t = 3 years

Find the Equation of the line that contains the point (-2,-8) and is parallel to the line 6x + 5y = 11. Write the equation in slope-intercept form.
Point :
Parallel lines have same slopes.
_________________________________
[tex]6x + 5y = 11[/tex]
Subtract sides -6x
[tex] - 6x + 6x + 5y = - 6x + 11[/tex]
[tex]5y = - 6x + 11[/tex]
Divided sides by 5
[tex] \frac{5}{5}y = \frac{ - 6}{5}x + \frac{11}{5} \\ [/tex]
[tex]y = - \frac{6}{5}x + \frac{11}{5} \\ [/tex]
Look :
This is the slope-intercept of the given line. We know that the coefficient of x is the slope of the linear functions in slope-intercept form.
Thus the slope of the line which we want is :
[tex]slope = - \frac{6}{5} \\ [/tex]
_________________________________
We have following equation to find the point-slope form of the linear functions.
[tex]y - y(given \: point) = (slope) \times (x - x(g \: p) \: ) \\ [/tex]
Now just need to put the slope and the coordinates in the above equation.
[tex]y - ( - 8) = - \frac{6}{5} \times (x - ( - 2) \: ) \\ [/tex]
[tex]y + 8 = - \frac{6}{5}(x + 2) \\ [/tex]
To find the slope-intercept form of the above equation we need to take the y alone and then simplifies the equation.
Look :
[tex]y + 8 = - \frac{6}{5}x - \frac{12}{5} \\ [/tex]
Subtract sides by -8
[tex]y + 8 - 8 = - \frac{6}{5}x - \frac{12}{5} - 8 \\ [/tex]
[tex]y = - \frac{6}{5}x - \frac{12}{5} - \frac{40}{5} \\ [/tex]
[tex]y = - \frac{6}{5}x - \frac{52}{5} \\ [/tex]
This is what we want...
_________________________________
Now we must Check the equation by using the given point :
[tex]( - 8) = - \frac{6}{5}( - 2) - \frac{52}{5} \\ [/tex]
[tex] - 8 = \frac{12}{5} - \frac{52}{5} \\ [/tex]
[tex] - 8 = \frac{ - 52 + 12}{5} \\ [/tex]
[tex] - 8 = \frac{ - 40}{5} \\ [/tex]
[tex] - 8 = - 8[/tex]
So the equation is right.
