i solved using brainly but i need to show my work what are the steps in solving please
Answers
Answer:
Step-by-step explanation:
to find the inverse first switch the x and y
y=log(x+3) inverse is x=log(y+3)
then change to exponential form to solve
[tex]log_{a} b=c[/tex] turns to[tex]a^{c}=b[/tex]
a is 10
b is y+3
c is x
[tex]10^{x} =y+3[/tex] subtract 3 from both sides
[tex]10^{x} -3=y[/tex]

14x^2=8y^2-6xy where x>0 and y>0 find the ratio x:y
Answers
Answer:
4 : 7
Step-by-step explanation:
First, you can start by moving all the terms to one side:
14x^2 + 6xy - 8y^2 = 0
Now we can start to factor this equation in order to find the ratio. We can start by factoring out the GCF, which is 2:
2(7x^2 + 3xy - 4y^2) = 0
In order to factor this equation we multiply the coefficients in front of the x^2 and y^2 term to get: 7 * -4 or -28. We are looking for numbers that have a product of -28 and a sum of 3(as the coefficient of the xy term). These two numbers are 7 and -4. We can rewrite the equation as:
2(7x^2 + 7xy - 4xy - 4y^2) = 0
Now, we can start to factor by grouping:
2( 7x[x + y] - 4y[x + y] ) = 0
And we can factor out [x + y]:
2(x + y)(7x - 4y) = 0
So, we can use the zero product property to get two equations:
x + y = 0
and
7x - 4y = 0
You get:
x = -y
and
7x = 4y
We can get cancel out the first solution because both x and y have to be positive. Rearranging the second equation we can get x : y = 4 : 7

Find the area of the polygon.
20 cm
14 cm
4 cm
3 cm
5 C
Answers
Answer:
The area of the given polygon is:
232 cm^2Step-by-step explanation:
To find the area of the polygon in the picture, you can divide the polygon in three rectangles: a 3 cm by 14 cm, a 5 cm by 14 cm rectangle, and the last rectangle must have a base of 12 cm (20 cm - 3 cm - 5 cm), and a height of 10 cm (14 cm - 4 cm). We can calculate the area of the rectangles with the formula below:
Area of a rectangle = Base * heightNow, we're gonna replace the measurements in the formula.
First rectangle:
Area of a rectangle = 3 cm * 14 cmArea of a rectangle = 42 cm^2Second rectangle:
Area of a rectangle = 5 cm * 14 cmArea of a rectangle = 70 cm^2Third rectangle:
Area of a rectangle = 12 cm * 10 cmArea of a rectangle = 120 cm^2By last, we must add the area of the rectangles:
Area of the polygon = 42 cm^2 + 70 cm^2 + 120 cm^2Area of the polygon = 232 cm^2As you can see, the area of the polygon in the picture is 232 cm^2.

Suppose Paul kicks a soccer ball straight up into the air with an initial velocity of 96 feet per second. The function h(t)= -16t^2+96t gives the height, in feet, of the soccer ball after t seconds. The function is shown in the graph below. What are the intercepts of the function and what do they mean?
Answers
Answer:
(d)
Step-by-step explanation:
Given
[tex]h(t) = -16t^2 + 96t[/tex]
Required
The intercepts
The x intercepts are where the graph crosses x axis.
From the attached plot, they are:
[tex]x = (0,0)[/tex] and [tex]x = (6,0)[/tex]
These represent the start and end of the ball that is launched.
Hence, (d) is true

In this composite function, (f◦g)(x) where f(x)=(X-3) and g(x)=X^2 what is (f◦g)(x) when x=1?
Answers
Answer:
When x = 1, (f◦g)(x) is -2.
Step-by-step explanation:
Composite function:
The composite function of f and g is given by:
[tex](f \circ g)(x) = f(g(x))[/tex]
In this question:
[tex]f(x) = x - 3, g(x) = x^2[/tex]
Composite function:
The composite function is:
[tex]f(g(x)) = f(x^2) = x^2 - 3[/tex]
At x = 1
[tex](f \circ g)(1) = 1^2 - 3 = 1 - 3 = -2[/tex]
So
When x = 1, (f◦g)(x) is -2.

10 Answer:
Referring to the Fig. in Question #4, find m∠7
Answers
Answer:
Step-by-step explanation:
The original angle of 30° is in a linear pair on a straight angle with ∠1. So since straight angles equal 180 subtract 30 from 180 to find m∠1, which is 150°.
The original angle of 30° is a vertical angle with ∠3, the same goes for ∠1 and ∠2. So those angles will be congruent. ∠1 = 30° and ∠2 = 150°
Lastly use corresponding angles to find out the values of ∠4, ∠5, ∠6, ∠7.
∠4 is corresponding to 30° so ∠4 is 30°
∠5 is corresponding to ∠1 so ∠5 is 150°
∠6 is corresponding to ∠2 so ∠6 is 150°
∠7 is corresponding to ∠3 so ∠7 is 30°
Hope this helps :)

Answer:
36
Step-by-step explanation:
I used a triangle height calculator on G0ogle
If the base area is 162 square inches, then the height of the pyramid will be 36 inches. Then the correct option is D.
What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
A pyramid has a volume of 1,944 inches cubed and a rectangular base with the dimensions of 18 inches by 9 inches.
Then the height of the pyramid will be
The volume of the pyramid will be
Volume = (Base area x height) / 3
Then the base area will be
Base area = 18 x 9
Base area = 162 square inches
Then the height of the pyramid will be
1944 = (162 h) / 3
5832 = 162 h
h = 36
