Can you find the Area
Answer:
We have to use heron’s formula to find the area of the triangle. Here a=7cm, b=9cm and c=12cm s = (a+b+c)/2 = (7+9+12)/2 = 28/2 = 14 Area of the triangle = √s(s-a)(s-b)(s-c) = √14(14-7)(14-9)(14-12) = √14×7×5×2 = √2×7×7×5×2 = √5×(2×2)×(7×7) = 14√5 cm^2 Hence area Of the triangle is 14√5 cm^2.

The y intercept of the inverse function of f(x) = 3/4 x + 12 is -16, option A is correct.
To find the y-intercept of f⁻¹(x), we can start by finding the inverse function f⁻¹(x) first.
Let y = f(x) = 3/4 x + 12
To find f⁻¹(x), we can first swap x and y, and then solve for y:
x = 3/4 y + 12
x - 12 = 3/4 y
4/3 (x - 12) = y
Therefore, f⁻¹(x) = 4/3 (x - 12)
The y-intercept of f⁻¹(x) is the value of f⁻¹(x) when x = 0.
f⁻¹(0) = 4/3 (0 - 12)
= -16
Hence, the y intercept of the inverse function of f(x) = 3/4 x + 12 is -16, option A is correct.

A rectangular gift box has dimensions that can be represented as shown in the figure. The volume of the box is 56w cubic inches. Which of the following is not a dimension of the box?
The dimension of the box is 12 by 7 by 8
How to calculate the volme of a boxThe volume of the box = lwh
Given the following
l = w
w = w - 5
h = w - 4
Hence;
w(w-5)(w-4) = 56w
Expand to have
(w^2-5w)(w-4) = 56w
w^3 - 4w^2 - 5w^2 + 20w = 56w
w^3 -9w^2 - 36w = 0
Factorize to get the value of w;
w(w^2-9w-36)=0
w^2 - 12w + 3w - 36 = 0
w(w-12) + 3(w-12)= 0
w = -3 and 12
Hence the dimension of the box is 12 by 7 by 8

find the distance between the two points rounding to the nearest tenth (if necessary)
(-7,-1) and (-4,3)
Answer:
The distance between these two points is of 5 units.
Step-by-step explanation:
Distance between two points:
Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
In this question:
Distance between (-7,-1) and (-4,3). So
[tex]D = \sqrt{(-4-(-7))^2+(3-(-1))^2} = \sqrt{3^2+4^2} = \sqrt{25} = 5[/tex]
The distance between these two points is of 5 units.

total of 89 items were sold, some at $20
each and the rest at $35 each.
Answer:
34 sold for $20
55 sold for $35
Step-by-step explanation:
20x+35y=2605
y=(98-x)
20x+35(89-x)=2605
Solve for x
20x+3115-35x=2605

Given the functions f(x), g(x), and h(x) shown below; list the functions from greatest to least by average rate of
change over the intervall
Answer:
f(x) > h(x) > g(x)
Step-by-step explanation:
For the average rate of change of a function between x = a and x = b,
Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]
From the table given,
Average rate of change of function 'f' between x = 1 and x = 3,
Average rate of change = [tex]\frac{f(3)-f(1)}{3-1}[/tex]
= [tex]\frac{15-7}{3-1}[/tex]
= 4
For the function 'g',
g(x) = 2x² - 18x
Average rate of change = [tex]\frac{g(3)-g(1)}{3-1}[/tex]
g(3) = 2(3)²- 18(3)
= 18 - 54
= -36
g(1) = 2(1)² - 18(1)
= 2 - 18
= -16
Therefore average rate of change = [tex]\frac{-36+16}{3-1}[/tex]
= -10
From the graph attached,
Average rate of change of the graph between x = 1 and x = 3,
Average rate of change = [tex]\frac{h(3)-h(1)}{3-1}[/tex]
h(3) = 7.5 [Although the graph is not clear]
h(1) = 2
Average rate of change = [tex]\frac{7.5-2}{3-1}[/tex]
= 2.75
Therefore, order of rate of change (from greatest to the least) for the given functions will be,
f(x) > h(x) > g(x)

2. A night with only 4 hours of sleep increases the amount of time it takes males to sprint 20 meters.
3. A post-lunch nap increases the amount of time it takes males to sprint 20 meters.
4. A post-lunch nap decreases the amount of time it takes males to sprint 20 meters.
Answer:
4. A post-lunch nap decreases the amount of time it takes males to sprint 20 meters.
Step-by-step explanation:
This question wants us to state the claim and the hypothesis.
This researchers claim can be found in the first sentence of this question.
Claim: post lunch nap decreases the time it takes to run for 20 meters.
The correct answer option for the claim is the 4th answer option. And it means that sleeping after lunch reduces the time it takes males to run in a 20m race.
B. Hypothesis

Sandra rode her bike 54 miles in one day. She rode 6 times the
number of miles Caleb rode his bike. How many miles did Caleb ride
his bike? Let b represent the number of miles Caleb rode his bike.
Ab 54 - 6
B 546 = 6
C 6 = 54
Answer:
54 = 6b
Step-by-step explanation:
Sandra rode her bike 54 miles in one day.
She rode 6 times the number of miles Caleb rode his bike.
Let Caleb rode b miles. It means,
54 = 6b
We can also find b as follows :
b = (54/6)
b = 9 miles
Hence, the required equation is "54 = 6b".
