Select the correct answer. Liam chooses an investment plan that requires him to make an initial investment of $8,000. Then he contributes equal monthly investments of $300 for the next 10 years. What function represents the amount in dollars that Liam has invested in terms of the number of months since he made the initial investment? A. Y = 8,000 − 300x B. Y = -8,000 + 300x C. Y = 8,000 + 300x D. Y = 300 − 8,000x E. Y = 300 + 8,000x
Answer: C. Y = 8,000 + 300x
Step-by-step explanation:
Given: Initial investment = $8,000
Monthly investment = $300
Let x = the number of months since he made the initial investment.
Y= the amount in dollars that Liam has invested.
Now , Amount invested = Initial investment + (Monthly investment) x ( number of months)
Y = 8000 + 300x
Hence, the required function : Y = 8000 + 300x
So, the correct option is C. Y = 8,000 + 300x

A circle has a center at the origin and the point (3,4) is on the circle
Answer: 5 units
Step-by-step explanation:
The standard form of equation of circle:
[tex](x-h)^2+(y-k)^2=r^2[/tex] , where (h,k) = center of circle, r= radius.
Given : Center of circle= origin = (0,0) =(h,k)
Point on circle = (3,4)
Put x= 3 , y=4 , h=0 , k=0 , then the equation will become
[tex](3-0)^2+(4-0)^2=r^2\\\\\Rightarrow\ 9+16=r^2\\\\\Rightarrow\ 25=r^2\\\\\Rightarrow\ r=5[/tex]
Hence, the radius is 5 units long.

A biologist investigates the growth of a special flower. It is estimated that
the height (in cm) of the flower is given by f(t) = at² + bt + C, where t is
the number of days passed since the start of the investigation. It is given
that the height of the flower first increases and then decreases.
What is the domain of f(t)?
Answer:
The domain of this function is:
Domain f(t): t ≥ 0
or
Domain f(t): {x ∈ R | t ≥ 0}
Step-by-step explanation:
Given the function of the height (in cm) of the flower
f(t) = at² + bt + C
Here,
t is the number of days passed since the start of the investigation.f(t) represents the height (in cm)Given that height of the flower first increases and then decreases.
The current function represents the quadratic function because it is of the form. Hence, the graph would be a curve.
f(x) = ax²+ bx + c
where a, b and c are the real numbers and a≠0
Normally the domain of quadratic is the set of all real numbers, but here in this case x-values consist of the time in terms of the number of days.
As the time in terms of a number of days can not be negative. Therefore, we conclude that:
The domain of this function is:
Domain f(t): t ≥ 0
or
Domain f(t): {x ∈ R | t ≥ 0}

Step-by-step explanation:
Let's use PEMDAS here
P: N/A
E: To transform [tex]5^{x}[/tex] to [tex]5^{3x}[/tex], we put [tex]5^{x}[/tex] to the power of 3.
M: We multiply 2 to [tex]5^{3x}[/tex], stretching the function by 2
M: We multiply -1 to [tex]2*5^{3x}[/tex], flipping the function vertically over x=0 (this is interchangeable with multiplying 2)
D: N/A
A: We add 8, moving the function to the right by 8

if the equation of L1 is 4x-2y=6 what is the x intersept?
Write the equation of L in slope intersept form
Write the slope of L.
Answer:
The x intercept: (1.5, 0)
The slope intercept form: y = 2x - 3
The slope: m = 2
Step-by-step explanation:
x intercept means y=0
4x - 2y = 6
4x - 2·0 = 6
4x = 6
x = 1.5
The slope intercept form is: y = mx + b
4x - 2y = 6 {subtract 4x from both sides}
- 2y = - 4x + 6 {dividing both sides by (-2)}
y = 2x - 3 ← slope intercept form
Slope is the number by x, in slope intercept form of line's equation

Step-by-step explanation:
Logarithms
The model that predicts the percentage of voters (V) as a function of the number of years (t) is:
[tex]V(t)=100-30\cdot e^{-0.04t}[/tex]
It's required to find in how many years the value of V will be V=80%. The equation to solve is:
[tex]100-30\cdot e^{-0.04t}=80[/tex]
Subtracting 100:
[tex]-30\cdot e^{-0.04t}=80-100=-20[/tex]
Dividing by -30:
[tex]\displaystyle e^{-0.04t}=\frac{20}{30}[/tex]
Applying logs:
[tex]\displaystyle \log( e^{-0.04t})=\log\left(\frac{20}{30}\right)[/tex]
For logs property:
[tex]\displaystyle -0.04t\log(e)=\log\left(\frac{20}{30}\right)[/tex]
log(e)=1. Solving for t:
[tex]\displaystyle t=\frac{\log\left(\frac{20}{30}\right)}{-0.04}[/tex]
Since 0.04=1/25:
[tex]\boxed{\displaystyle t=-25\log\left(\frac{20}{30}\right)}[/tex]

The image of a point (1, 2) under a translation is (-5, -4) what is the translation vector
Answer:
u = vector (-6 , -6)
Step-by-step explanation:
u = vector(a , b)
Left (-) 6 units and down (-) 6 units
The translation vector for the image is (-6,-6).
What is a translation vector?A translation vector is a type of transformation that moves a figure in the coordinate plane from one location to another. Vectors are given in the form ( x y ) where x is the movement horizontally and y is the movement vertically.
For the given situation,
The image of a point (1, 2) under a translation is (-5, -4) .
The translation vector can be found by calculating the movement horizontally and vertically as
⇒ [tex](-5-1,-4-2)[/tex]
⇒ [tex](-6,-6)[/tex]
Hence we can conclude that the translation vector for the image is (-6,-6).

In triangle Jkl, l = 880 inches, Angle j=63° and Angle k=11°. Find the length of j , to the nearest
inch.
Answer:
j=816 inch
Step-by-step explanation:
J^+K^+L^=180° (sum of int. angles of triangle)
L^+11+63=180
L^=106°
j/sinJ=l/sinL
j/sin63=880/sin106
j*sin106/sin106=880*sin63/sin106
j=815.6
j=816 inch
