The value of the y-intercepts of f(x) and g(x) is f(0), g(0) which gives -4.
What is an equation?An equation is an expression that shows the relationship between two or more variables and numbers.
The y intercept of an equation is the value of the function when x = 0.
Given that f(x) = -4(1.09)ˣ
f(0) = -4(1.09)⁰ = -4
From the table of g(x), when x = 0, g(0) = -4
The value of the y-intercepts of f(x) and g(x) is f(0), g(0) which gives -4.

A local dry cleaner interviewed 15 candidates for the positions of cashier, washer, and delivery driver. How many ways can
they fill the 3 positions?
18
45
455
2,730
Answer:
D. 2730
Step-by-step explanation:
I just had this question on FLVS yesterday.
you use factorials for this:
15!/12!
15*14*13*12!/12!
15*14*13
2730
Number of ways in which 3 positions can be filled are 2730.
What is permutation and combinations?The number of ways in which objects from a set may be selected, generally without replacements, to form subsets. This selection of subset is called permutation when order of selection is a factor.
If n things taken r at a time and n! = n × (n-1) × (n-2) × (n-3)..........3 × 2 × 1
⇒Permutation,
[tex]P(n,r) =\frac{n!}{(n-r)!}[/tex]
Now it is given that number of candidates, n = 15
and number of position, r = 3
Hence number of ways positions can be filled-
[tex]P(n,r) =\frac{15!}{(15-3)!}[/tex]
⇒ [tex]P(15,3) =\frac{15!}{12!}[/tex]
⇒ P(15,3) = (15 × 14 × 13)12!/12!
⇒ P(15,3) = (15 × 14 × 13)
⇒ P(15,3) = 2730
∴ Number of ways in which 3 positions can be filled are 2730.

A can of soup has a height of 10 cm. If the volume of the can is 363 cubic cm, what is its radius?
The radius of the circular cross-section of the can of soup is; 3.4cm.
What is the radius of the can of soup?Since, the can has a height of 10cm and the volume of the can is 363cm³, it follows that the area of the circular cross-section can be evaluated as;
A = 363/10 = 36.3cm²
Hence, it follows that the radius can be evaluated as follows;
36.3 = 3.14 × r²
r² = 36.3/3.14

A distance travaled by train in three hours with a constant speed of r miles per hour
The distance travelled by the train with constant speed of r miles will be 3r.
What is Speed?The most crucial scientific notion is measurement. Base or physical fundamental units are used to quantify a wide range of quantifiable quantities. One such measurable metric is speed, which calculates the ratio between the distance an object travels and the time needed to cover that distance. Let's explore speed in-depth in this session. The pace at which an object's location changes in any direction. When an object travels the same distance in the same amount of time, it is said to be moving at a uniform speed. When an object travels a different distance at regular intervals, it is said to have variable speed.We know the formula of distance linking the speed and the time.
Distance = speed × time
Substituting the given values to get:
Distance = r × 3
Distance = 3r

The approximate solution of the above equation is: 55/15 (Option A). This is solved using the quartic formula, not quadratic equation.
What is the Quartic Formula?
The quartic formula has up to four various solutions including real and imaginary numbers. Read on for more explanation.
What is the solution to the above question?
First we restate the above equation:
x²-3x+2= √(x-2) + 2
Next we remove square roots
[tex]x^{4}[/tex] - 6x³ + 9x² = x - 2
Add two to both sides
→ [tex]x^{4}[/tex] - 6x³ + 9x²+2 = x - 2 +2
→ [tex]x^{4}[/tex] - 6x³ + 9x²+2 = x
Subtract X from both sides
→ [tex]x^{4}[/tex] - 6x³ + 9x²+2 -x = x -x
→ [tex]x^{4}[/tex] - 6x³ + 9x²+2 - x= 0
Using the Quartic formula to solve the fourth order equation:
a[tex]x^{4}[/tex] + bx³ + cx² + dx + e
The resolution of x is given as:
x = 2.691085, 3.346753
Because the fraction nearest to 3.4 is 55/16

Thank you!
Using the given linear function of best-fit, the most likely approximate height of the plant after 8 weeks would be of 7.4 centimeters.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.The line of best-fit goes through points (0,1) and (5,5). Point (0,1) means that the y-intercept is of b = 1. The slope is given as follows:
m = (5 - 1)/(5 - 0) = 4/5 = 0.8.
Hence the equation that gives the approximate height after x weeks is:
y = 0.8x + 1.
After 8 weeks, the expected height is:
y = 0.8 x 8 + 1 = 6.4 + 1 = 7.4 centimeters.

Move to triangle CDR:
15 is length opposite the angle we're after.
So far, we've got the hypotenuse (which we just found to be 33.04....) & the opposite of our triangle
Hypotenuse & opposite = SOH
Sin(x) = 15/33.04... but, to find the angle we do inverse of sin
sin-1(15/33.04...) = x
x = 27

Complete the point-slope equation of the line through-8,-8) and (7, 9)
Answer:
[tex]y = \frac{17}{15}x + \frac{16}{15}[/tex]
Step-by-step explanation:
So the slope-intercept form is given as: y=mx+b where m is the slope and b is the y-intercept (since if you plug in 0 as x, mx will be 0 leaving only b). You can calculate the slope with the slope formula: [tex]slope=\frac{y_2-y_1}{x_2-x_1}[/tex] which is essentially [tex]\frac{rise}{run}[/tex]. So for this example (-8, -8) will be ([tex]x_1, y_1[/tex]) and (7, 9) will be ([tex]x_2, y_2[/tex]).
Plug values into equation:
[tex]\frac{9 - (-8)}{7 - (-8)}[/tex]
cancel out negatives
[tex]\frac{9+8}{7+8}\\[/tex]
Simplify
[tex]\frac{17}{15}[/tex]
The fraction is in the most simplified form unless you want to have a mixed fraction, otherwise you can't do anything else to the fraction.
so now we have the slope we have one part of the equation: [tex]y=\frac{17}{15}x + b[/tex], but now we need to solve for b. This can be done by using either of the points and plugging in x and y, but for this example I'll use (7, 9).
Plug in (7, 9) as (x, y)
[tex]9 = \frac{17}{15}(7) + b[/tex]
Multiply
[tex]9 = \frac{119}{15}+b[/tex]
Subtract
[tex]9-\frac{119}{15}=b[/tex]
Rewrite 9 as a fraction
[tex]\frac{135}{15} - \frac{119}{15} = b[/tex]
Subtract numerators
[tex]\frac{16}{15} = b[/tex]
now we have both pieces of information
[tex]y = \frac{17}{15}x + \frac{16}{15}[/tex]

Answer:

Step-by-step explanation:
In the first sequence, notice that each term increases by a factor of 8 (multiplied by 8 each time). Therefore, the fourth term would be 64*8 = 512, so the fifth term is 512*8 = 4096.
In the second sequence, each term decreases by a factor of 2 (divided by 2 each time). The fourth term would be 500/2 = 250, so the fifth term is 250/2 = 125.
