The graphs of f(x) and g(x) are shown below:
Graph of function f of x open upward and has its vertex at negative 7, 0. Graph of function g of x opens upward and has its vertex at negative 7, negative 2.
If f(x) = (x + 7)2, which of the following is g(x), based on the translation?
g(x) = (x + 9)^2
g(x) = (x + 5)^2
g(x) = (x + 7)^2 + 2
g(x) = (x + 7)^2 − 2
rewrite the equation 12x=13-x^2
Answer:
x^2+12x-13 = 0
Step-by-step explanation:
12x=13-x^2
=>12x+x^2=13-x^2+x^2
=>x^2+12x-13 = 13-13
=> x^2+12x-13 = 0
Answer:
x² + 12x - 13 = 0
Step-by-step explanation:
12x = 13 - x²
the standard form of an equation is written starting from the variable of the highest degree to the lowest. Hence after rearranging;
0 = 13 - x² - 12x
0 = -x² - 12x + 13
In an equation, the highest degree of a variable should preferably be postive hence the equation to the left side to remove the negative sign:
x² + 12x - 13 = 0
In the morning, the number of ducks at the reservoir was 80. By noon, the reservoir had 135 ducks. What was the percent of change in the number of ducks? Round your answer to the nearest whole percent.
Answer:
60 percent
Step-by-step explanation:
number of ducks in morning=80
ducks in after noon=135
for percentage
80/135=0.5925=0.60
0.60*100=60 percent

Sean solved a quadratic equation by factoring.
The problem he solved is given. Complete the
four blanks shown for one of his steps and the
solution
Step-by-step explanation:
Here are the steps required for Solving Quadratics by Factoring:
Step 1: Write the equation in the correct form. To be in the correct form, you must remove all parentheses from each side of the equation by distributing, combine all like terms, and finally set the equation equal to zero with the terms written in descending order.
Step 2: Use a factoring strategies to factor the problem.
Step 3: Use the Zero Product Property and set each factor containing a variable equal to zero.
Step 4: Solve each factor that was set equal to zero by getting the x on one side and the answer on the other side.
Example 1 – Solve: x2 + 16 = 10x
Step 1: Write the equation in the correct form. In this case, we need to set the equation equal to zero with the terms written in descending order.
Step 1
Step 2: Use a factoring strategies to factor the problem.

The volume of a large tank is 210 ft3. It is 6 2/3 ft wide and 2 4/5ft high. What is the length of the tank?
Multiply the width by the height:
6 2/3 x 2 4/5 = 18 2/3 square feet.
Now divide the volume by that number:
210 / 18 2/3 = 11 1/4
The length of the tank is 11 1/4 feet

find the value of tan30+cot30+sin60
Hello!
This is a problem about relating values of the Unit Circle.
First, we need to figure out the specific "points" of each angle measure of 30 and 60.
For the angle measure 30, the point will be [tex](\frac{\sqrt{3}}{2},\frac{1}{2})[/tex].
For the angle measure 60, the point will be [tex](\frac{1}{2},\frac{\sqrt{3}}{2})[/tex].
The tangent value of a point will be its [tex]y[/tex] value over its [tex]x[/tex] value.
[tex]\frac{\frac{1}{2}}{\frac{\sqrt{3}}{2}}=\frac{1}{2}*\frac{2}{\sqrt{3}}=\frac{1}{\sqrt{3}}=\frac{\sqrt{3}}{3}[/tex]
The cotangent value of a point will be the reciprocal of the tangent value, which we found previously.
[tex]\frac{3}{\sqrt{3}}=\frac{3\sqrt{3}}{3}=\sqrt{3}[/tex]
The sine value of a point will be the [tex]y[/tex] value of the point.
[tex]\frac{\sqrt{3}}{2}[/tex]
So the values we have so far are [tex]\frac{\sqrt{3}}{3}+\sqrt{3}+\frac{\sqrt{3}}{2}[/tex]
Now we have to find the LCD to add these together, which in this case would be 6.
[tex]\frac{2\sqrt{3}}{6}+\frac{6\sqrt{3}}{6}+\frac{3\sqrt{3}}{6}[/tex]
Which adds up to [tex]\frac{11\sqrt{3}}{6}[/tex], which is in simplest radical form.
Hope this helps!
Constance's car has a 12-gallon gas tank and can travel 25 miles on one gallon of gas. Constance begins with a full tank of gas and drives at a constant rate of 40 miles per hour. How many hours can you she drive before her car runs out of gas
Answer:
7.5 hours
Step-by-step explanation:
12 x 25 = 300
the distance she can travel with a full tank of gas is 300 miles
300 = 40t
300/40 = t
7.5 = t

Solve for the area of the figure below and show work.
Answer and Step-by-step explanation:
1. We can see that this kite-shape has 4 triangles in it.
The area of a triangle is as follows:
[tex]A = \frac{bh}{2}[/tex]
Where:
b = Base (length)
h = Height
Top Right Triangle Area:
b = 9
h = 3
A = [tex]\frac{3 * 9}{2}[/tex]
A = [tex]\frac{27}{2}[/tex]
Bottom Right Triangle Area:
b = 9
h = 3
A = [tex]\frac{3 * 9}{2}[/tex]
A = [tex]\frac{27}{2}[/tex]
Top Left Triangle Area:
b = 4
h = 3
[tex]A = \frac{4*3}{2}[/tex]
A = [tex]\frac{12}{2}[/tex]
A = 6
Bottom Left Triangle Area:
b = 4
h = 3
[tex]A = \frac{4*3}{2}[/tex]
A = [tex]\frac{12}{2}[/tex]
A = 6
Now, we add all the areas together to get the area of the kite figure.
A = [tex]\frac{27}{2}[/tex] +
A = 27 + 12
A = 39
The area of the kite figure is 39 [tex]m^{2}[/tex].
2. We have to find the area of the trapezoid.
(I'm not sure if the 9 is for the entire bottom side length)
If the bottom side length is 9, then we would use the formula:A = [tex]\frac{a + b}{2} h[/tex]
to find the area of the entire trapezoid.
A = [tex]\frac{2.4 + 9}{9}[/tex] × 8.2
A ≈ 46.74 [tex]mi^{2}[/tex]

Tom needs to plow 1.1 acres of land. If he can plow 5.5 acres in an hour, how many hours will it take?
Help! (16 pts if you answer!)
Given:
Tom needs to plow 1.1 acres of land.
He can plow 5.5 acres in an hour.
To find:
The time taken by Tom to plow 1.1 acres of land.
Solution:
We have,
Time take by Tom to plow 5.5 acres = 1 hour
Time take by Tom to plow 1 acre = [tex]\dfrac{1}{5.5}[/tex] hour
Time take by Tom to plow 1.1 acres = [tex]\dfrac{1.1}{5.5}[/tex] hour
= [tex]0.2[/tex] hour
Therefore, the time taken by Tom to plow 1.1 acres of land is 0.2 hour.

Answer:
The perimeter of the triangle is 34 cm
Step-by-step explanation:
Here, we want to find the perimeter of the triangle
This is simply the sum of the side lengths
mathematically, the distance of two lines from a point touching the circle is the same
so, on the other sides, we have the missing sides as;
5cm, 4 cm and 8 cm
So the perimeter will be;
4cm + 5cm + 8 cm + 4 cm + 8 cm + 5 cm = 34 cm
