Answer:
[tex]y = 7(3^x)[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1) = (0,7)[/tex]
[tex](x_2,y_2) = (4,567)[/tex]
Required
Determine the formula
An exponential function is of the form:
[tex]y = ab^x[/tex]
For point [tex](x_1,y_1) = (0,7)[/tex]
[tex]7 = ab^0[/tex]
[tex]7 = a*1[/tex]
[tex]7 = a[/tex]
[tex]a = 7[/tex]
For point [tex](x_2,y_2) = (4,567)[/tex]
[tex]567 = ab^4[/tex]
Substitute 7 for a
[tex]567 = 7*b^4[/tex]
Divide both sides by 7
[tex]81 = b^4[/tex]
Take 4th root of both sides
[tex]\sqrt[4]{81} =\sqrt[4]{b^4}[/tex]
[tex]\sqrt[4]{81} =b[/tex]
[tex]b = \sqrt[4]{81}[/tex]
[tex]b = 3[/tex]
Substitute 7 for a and 3 for b in [tex]y = ab^x[/tex]
[tex]y = 7 * 3^x[/tex]
[tex]y = 7(3^x)[/tex]

Which graph represents the function y = sine (one-half x) after a shift of 3 units down?
The graph shows the function y=sin(1/2x) after a shift of 3 units down .
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
We have to find the graph which represents the function y = sine (1/2x) after a shift of 3 units down
The sine function starts at 0, heads up to 1 by π/2 radians (90°) and then heads down to −1.
According to the question
y=sin(1/2x) after a shift of 3 units down
y+3=sinx/2
Now.
x y
0 -3
π -2
-π -4
Graph will be plotted on these points
Hence, the graph shows the function y=sin(1/2x) after a shift of 3 units down .

1. George joins a gym. He pays $25 to sign up and then $15 per month.
How much will George have to pay if he uses the gym for 5 months? Show your work.
Answer:
100 dollars
Step-by-step explanation:
First you multiply how much it is each month by how many months.
5x15=75
Then you add the money he has to pay to sign up. So,
75+25=100
Answer:
I believe the answer would be $100
Step-by-step explanation:
1. He already payed the $25 so he doesn't need to pay that anymore
2. If he's paying $15 a month you would have to multiply 15 by 5 because he went for 5 months
3. for the five months he payed $75, so after that you would have to add the additional $25 to the $75 get the answer of $100

Let v =LeftAngleBracket negative 10, 15 RightAngleBracket. What is the approximate direction angle of One-halfv? 34° 56° 124° 304°
Answer:
C. 124
Step-by-step explanation:
The approximate direction angle of One-half of v will be 304°. Then the correct option is D.
What is a vector?The quantity which has magnitude, direction and follows the law of vector addition is called a vector.
The equation of vector is given below.
v = < –10, 15 >
Then the approximate direction angle of One-half of v will be
v/2 = < –5, 7.5 >
Then the angle will be
tan θ = 7.5/(–5)
tan θ = –1.5
θ = tan⁻¹(–1.5)
θ = –56°
θ = –56° + 360°
θ = 304°
Then the correct option is D.

The vertex of this parabola is at (3,-2). When the x-value is 4, the y value is 3. What is the coefficient of the squared term in the parabola's equation?
Answer:
the coefficient of the squared expression is 5.
Step-by-step explanation:
the equation of a parabola in its vertex form is y=a(x-h)²+k, where (h, k) is the vertex of the parabola.
in this case, h=3, k=-2, so y=a(x-3)-2
plug (4,3) in the equation: 3=a(4-3)²-2, a=5
