Answer:
The equation of the exponential function will be:
[tex]y\:=\:10\cdot \left(\frac{1}{5}\right)^x[/tex]Step-by-step explanation:
The general exponential function is defined as
y = abˣ
Here,
a is the initial value and b is the growth factorFrom the table, it is clear that the y-intercept is (0, 10). Note that the y-intercept can be determined by setting x=0 and solving for y.
here
at x=0, y=10
so a = 10
If we check the y-values, it is clear that every next value of y can be obtained by multiplying the previous y-value by 1/5.
In other words, the common multiplier = b = 1/5
Thus, the equation becomes
[tex]y\:=\:10\cdot \left(\frac{1}{5}\right)^x[/tex]
Thus, the equation of the exponential function will be:
[tex]y\:=\:10\cdot \left(\frac{1}{5}\right)^x[/tex]Write the importance of mathematics in your education describing in your own words

Ben had $100 in his savings account. He adds $5.00 a week to his savings as shown in the graph below. According to this graph, how much money does he have in his savings account after 8 weeks?
A. $40
B. $135
C. $140
D. $145
Answer:
Option (C)
Step-by-step explanation:
Let the relation between amount of money (m) and Time (t) is represented by the equation,
m = ct + b
Where c = Investment per week
b = Ben already had the amount before investment
From the question,
c = $5 per week
b = $100
Therefore, equation will be,
m = 5t + 100
If duration of the investment 't' = 8 weeks
Amount in the account after 8 weeks,
m = 5(8) + 100
m = $140
Option (C) is the correct option.

two square are congruent ,if they have same _____
Answer:
Two squares are congruent if they have the same side length
Step-by-step explanation:
The dimensions of a square are the side length of the square and in a square, all sides are equal
Therefore, given that two quadrilaterals are squares, and the side length of each of the given quadrilateral are equal, the quadrilateral are said to be congruent.
Which expressions can be used to find m∠ABC? Select two options. cos−1(StartFraction 9.8 Over 6.3 EndFraction) cos−1StartFraction 6.3 Over 9.8 EndFraction) cos−1(StartFraction 7.5 Over 9.8 EndFraction) sin−1(StartFraction 9.8 Over 7.5 EndFraction) sin−1(StartFraction 7.5 Over 9.8 EndFraction)
Answer:
B. [tex]Cos ^{-1}[/tex] [tex]\frac{6.3}{9.8}[/tex]
E. [tex]Sin^{-1}[/tex] [tex]\frac{7.5}{9.8}[/tex]
Step-by-step explanation:
The trigonometric functions are applied when given a side and one of the angles of a right angled triangle.
Sine θ = [tex]\frac{opposite}{hypotenuse}[/tex]
Cosine θ = [tex]\frac{adjacent}{hypotenuse}[/tex]
Tangent θ = [tex]\frac{opposite}{adjacent}[/tex]
Given that; hypotenuse = 9.8, opposite side = 7.5 and adjacent side = 6.3.
Then,
Sin θ = [tex]\frac{7.5}{9.8}[/tex]
⇒ θ = [tex]Sin^{-1}[/tex] [tex]\frac{7.5}{9.8}[/tex]
Also,
Cos θ = [tex]\frac{6.3}{9.8}[/tex]
⇒ θ = [tex]Cos ^{-1}[/tex] [tex]\frac{6.3}{9.8}[/tex]
So, the appropriate answers to the given questions are options B and E.

Use point-slope form to write a linear equation to represent the growth of Claire over time. Then, simplify the equation and write it in slope-intercept form. Identify the y-intercept. Show your work.
Complete Question:
The growth of baby girl Claire is displayed in the graph below. (4, 22) (14, 30)
Answer:
Point Slope: [tex]y - 22 = 0.8(x - 4)[/tex]
Slope Intercept: [tex]y = 0.8x +18.8[/tex]
y intercept: [tex]b = 18.8[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1) = (4,22)[/tex]
[tex](x_2,y_2) = (14,30)[/tex]
Solving (a) Point slope
Using point slope form, an equation is of the form
[tex](y_2 - y_1) = m(x_2 - x_1)[/tex]
First, we need to solve for slope (m):
Make m the subject
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Substitute values for x and y
[tex]m = \frac{30 - 22}{14 - 4}[/tex]
[tex]m = \frac{8}{10}[/tex]
[tex]m = 0.8[/tex]
Next, we form a linear relationship
[tex]y - y_1 = m(x - x_1)[/tex]
Where
[tex]m = 0.8[/tex] and [tex](x_1,y_1) = (4,22)[/tex]
[tex]y - 22 = 0.8(x - 4)[/tex]
Solving (b): Slope Intercept
[tex]y - 22 = 0.8(x - 4)[/tex]
Open Bracket
[tex]y - 22 = 0.8x - 3.2[/tex]
Add 22 to both sides
[tex]y - 22 +22= 0.8x - 3.2 + 22[/tex]
[tex]y = 0.8x +18.8[/tex]
Solving (c): The y intercept
The general form of an equation is:
[tex]y = mx + b[/tex]
Where b represents the y intercept
By comparison with [tex]y = 0.8x +18.8[/tex]
[tex]b = 18.8[/tex]

PLEASE HELP FAST! my two problems are in the photo.
Answer:
8.) x=115 degrees
9.) y=102 degrees
Step-by-step explanation:
8.) A triangles total degrees is 180, so 180-50=130. now the missing angles are congruent, so 130/2=65. and now we're working on the bottom right angle. which is 65. what we need can be added to the angle we just found to add up to 180, so reverse it. 180-65=115. so x=115 degrees.
9.) because y is congruent to the angle across from it, we can just assume y and 78 is equal to 180. 180-78=102. so y=102 degrees. Hope this helps!
Are the expressions -0.5(3x + 5) and -1.5x + 2.5 equivalent? Explain why or why not.

Answer:
Step-by-step explanation:
Expanding the first statement using the distributive property yields -1.5x - 2.5. The two formulations are not equal because the constant term does not have the same sign as the second expression. Furthermore, if you replace x with a value and evaluate each equation, the results will not be equal.
