Answer:
9x² - 24x + 16
Step-by-step explanation:
Formula for the area of the square base = s²
Where,
s = side length = 3x - 4
Therefore:
Area of the base = (3x - 4)²
Expand
(3x - 4)(3x - 4)
3x(3x - 4) -4(3x - 4)
Apply the distributive property
9x² - 12x - 12x + 16
Add like terms
9x² - 24x + 16
Area of the base in standard form = 9x² - 24x + 16
Answer:
9x^2 -24x +16 units^2
Step-by-step explanation:
(3x-4)^2 = 9x^2 -24x +16

Answer:
3.53
Step-by-step explanation:
(pythagoras theorem | year 9)
Answer:
In this case, to prove what is required, we must use the Pythagorean theorem to find the diagonal of the square.
If the diagonal of the square is smaller than the diameter of the circle, then the square will fit perfectly in the circle without touching it.
Diagonal = Root ((7 ^ 2) + (7 ^ 2)) = 9.89 cm.
we observed that
9.89cm <11cm.
Therefore we show that:
the square will fit inside the circle without touching the edge of the circle
or
c^2 = a^2 + b^2 c^2 = 7^2 + 7^2 = 49 +49 c^2 = 98 c = sqrt 98 c = 9.8 cm c = diagonal of square (9.8 cm) and is less than the diameter of the circle (11 cm), so the square will fit inside the circle without touching the edge of the circle.
I hope this helps a little bit.

The first triangle is dilated to form the second triangle. What is the scale factor? Please show your math work step by step.
Answer:
2.5 is the scale factor
Step-by-step explanation:
Skills needed: Identifying the Scale Factor, Division
1) First, we need to understand what the scale factor is.
A scale factor is the value being multiplied by one side of a figure to form another figure that is bigger or smaller. For example:
Let's say you are given a triangle with side lengths 3 cm, 4 cm, and 5 cm and you are supposed to find the side lengths of a new triangle when the scale factor being used is 2. Here, you would multiply all the sides by the value 2. So, the 3 sides are:3 x 2, 4 x 2, and 5 x 2 ---> 6 cm, 8 cm, 10 cm.
2) So to find the scale factor in a problem, you would do the side of one triangle divided the corresponding side of the other triangle.
So to find the scale factor in the above problem (if we were only given side lengths 3 cm, 4 cm, and 5cm & also 6 cm, 8 cm, and 10 cm), you would do:
[tex]\frac{6}{3}[/tex] or [tex]\frac{8}{4}[/tex] or [tex]\frac{10}{5}[/tex], all of which equal 2.
3) So in this problem, you would simply do [tex]\frac{10}{4}[/tex], since 10 and 4 are corresponding sides of dilated triangles.
This is [tex]\frac{5}{2}[/tex] when simplified, or 2.5 as a decimal, since scale factors are usually expressed as decimals.
Hope this helps and have a nice day!! :) :] :D

Answer:
Option C
Step-by-step explanation:
Domain is the set of x-values of the function.
Similarly, Range of a function is defined by the set of y-values of the function.
For the given set of domain → {0, 3, 7}
Range of function → f(x) = 2ˣ + 4
x 0 3 7
f(x) 2⁰+ 4 = 5 2³+ 4 = 12 2⁷ + 4 = 132
Therefore, range of the given function will be → {5, 12, 132}
Option C will be the answer.

A limited-edition poster increases in value each year with an initial value of $18. After 1 year and an increase of 15% per year, the poster is worth $20.70. Which equation can be used to find the value, y, after x years? (Round money values to the nearest penny.) y = 18(1.15)x
Answer:
[tex]y = 18 * 1.15^x[/tex]
Step-by-step explanation:
Given
[tex]a = 18[/tex] --- initial
[tex]r =15\%[/tex] -- rate
Value after a year = $20.70
Required
Expression to calculate its value after y years
This is calculated using:
[tex]y = ab^x[/tex]
Where
[tex]b=1 +r[/tex]
Substitute [tex]r =15\%[/tex] in [tex]b=1 +r[/tex]
[tex]b = 1 + 15\%[/tex]
[tex]b = 1 + 0.15[/tex]
[tex]b = 1.15[/tex]
Substitute [tex]b = 1.15[/tex] and [tex]a = 18[/tex] in [tex]y = ab^x[/tex]
[tex]y = 18 * 1.15^x[/tex]

what ratio below is not equivalent to the ratio 10:35
Answer:
1/2
Step-by-step explanation:
In a ratio, two quantities are compared using division. It is used to indicate how big or small a quantity is when compared to another. Here among the given options only 2:7 is equivalent to 10:35. The correct options are A, B and C.
What is a ratio?The ratio is defined as the comparison of two quantities of the same units. It indicates how much of the one quantity is present in the other quantity. The ratio are generally of two types, they are part to part ratio and part to whole ratio.
The part to part ratio denotes how distinct the entities or groups are related whereas the part to whole ratio denotes the relationship between a specific group to a whole. We use the ratio formula while comparing the relationship between two numbers or quantities.
Thus the correct option is A, B and C.

Write an equation of a parabola opens upwards and has vertex (7, - 6).
Any help?
Answer:
f(x) = x² - 14x + 43
Step-by-step explanation:
The equation of a parabola in vertex form is
f(x) = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k ) = (7, - 6 ) , then
f(x) = a(x - 7)² - 6
Since the parabola opens upwards then a > 0
let a = 1
f(x) = (x - 7)² - 6 ←in vertex form
f(x) = x² - 14x + 49 - 6
f(x) = x² - 14x + 43 ← in standard form
A pilot spots the airport at an angle of depression of 16°. The plane is flying at an altitude of 9,000 ft. What is the ground distance (distance along the ground) from the plane to the airport to the nearest foot
Answer:
[tex]31,387\:\text{ft}[/tex]
Step-by-step explanation:
We can form a right triangle using the plane, the airport, and ground and use basic trig for a right triangle to solve this problem.
In a right triangle, [tex]\tan\theta=\frac{\text{opp}}{\text{adj}}[/tex]. Therefore, we have the following equation, where [tex]x[/tex] is ground distance between the plane and the airport:
[tex]\tan 16^{\circ}=\frac{9,000}{x},\\x=\frac{9,000}{\tan 16^{\circ}},\\x\approx \boxed{31,387\:\text{ft}}[/tex].

Answer:
7. 6
8. 6
9. 12
10. 6
11. 12
12. 24
Step-by-step explanation:
The length of each segment is AB = 6, BC = 6, AC = 12, CD = 6, CE = 12, AE = 24
What is the length?It is the measure of distance between the two points is called a length.
D is the mid-point of CE. Then
CD = DE = 6
B is the mid-point of AC. Then
AB = BC
C is the mid-point of AE. Then
AC = CE
AB + BC = CD + DE
AB + AB = CD + CD
2 AB = 2 CD
AB = CD
AB = 6
Then
AB = 6
BC = AB = 6
AC = AB + BC = 6 + 6 = 12
CD = DE = 6
CE = CD + DE = 6 + 6 = 12
AE = AB + BC + CD + DE = 6 + 6 + 6 + 6 = 24

Answer:
16/1,000
Understanding place values:
The first 0 before the decimal point in 0.016 represents ones, the 0 after the decimal point represents tenths, the 1 represents hundredths and the 6 represents thousandths. We use 1,000 in our fraction because of the place value.
Step-by-step explanation:
1. Convert 0.016 into a fraction:
0.016 = 16/1,000
2. Simpilfy the fraction 16/1,000:
16/1,000 ÷ 8 = 2/125
2/125 is equivalent to 0.016

- You invest $80 into a simple interest savings account that earns 5% annually.
After how many years will the account have a total of 200$ in it?
Answer:
30 years.
Step-by-step explanation:
The equation for simple interest is I = PRT, where I = interest earned, P = principal/amount invested, R = rate as a decimal, and T = time in years.
Our unknown for this example is T, but first we have to see how much interest is earned.
200 - 80 = 120 in interest (starting with $80, ending with $200)
120 = (80)(0.05)(T)
120 = 4T
30 = T

Create an equation to solve for x using the trapezoid midsegment formula:
Answer:
Equation for x: 3x - 6 = [tex]\frac{2x - 1 + 25}{2}[/tex]
x = 9
CD = 17
GH = 21
Step-by-step explanation:
The midsegment formula for a trapezoid is
GH = [tex]\frac{CD + FE}{2}[/tex]
3x - 6 = [tex]\frac{2x - 1 + 25}{2}[/tex]
6x - 12 = 2x + 24
4x = 36
x = 9
CD = 2x - 1 = 2(9) - 1 = 18 - 1 = 17
GH = 3x - 6 = 3(9) - 6 = 3 = 27 - 6 = 21
