Answer:

x = -3

-3+2 = -1

-1 = f(x)

Freya begins started with 200 yards.

Freya then increased her distance by adding five yards a day for two days.

x = 200 + (n - 1)5.

[x = The distance Freya sprints on day 21]

x = 200 + (21 - 1)5

x = 200 +  (20) 5 = 300 yards

Answer:

[tex] a _ n = 200 + ( n - 1 ) 5 [/tex]

Step-by-step explanation:

We are given that initially, Freya started with sprinting 200 yards and then gradually increased the distance by adding 5 yards a day for 21 days.

So our initial value for distance is [tex]a_1=200[/tex]

and since she keeps on adding 5 yards everyday to her distance so this will be our common difference.

Therefore, the explicit formula will be:

[tex]a_n=200+(n-1)5[/tex]

Answer:

D

Step-by-step explanation:

First Rhonda makes a 20% down payment.  20% of $85 is:

0.20 × $85 = $17

So what's left is:

$85 - $17 = $68

So the number of monthly payments at $8 per month is:

$68 / 8 = 8.5

Rounding up, it will take 9 months to make all the payments.  If her father's birthday is on the third Sunday of June, she needs to make her ninth and final payment on June 1.  So her first monthly payment needs to be 8 months before that, or October 1.

Answer is D.

The bottom-left graph.

Step-by-step explanation:

g(1) = 0+1 = 1 => g(1) = 1

=> (1,1) ∈ Gf

The graph of the square root function is the bottom left graph.

We want to see which graph represents the function:

g(x) = √(x - 1) + 1

The first thing we can notice is that the domain of the function is:

x ≥ 1

We can see that when x  = 1 the function becomes:

g(1) = √(1 - 1) + 1

g(1) = 1

So the first point of this function is (1, 1), like in the graph in the bottom left, so that is the correct option.

Answer:

90% increase.

Step-by-step explanation:

Percent change in altitude = (difference in altitude * 100) / original altitude

= (95-50) * 100 / 50

= 90%.

Answer:

Percent of change in altitude = 90 %

Since the altitude increases from 50 ft to 95 ft the change is positive.

Step-by-step explanation:

Initial altitude, = 50 ft

Final altitude, = 95 ft

Increase in altitude = 95 - 50 = 45 ft

Percentage increase

              [tex]=\frac{45}{50}\times 100=90\%[/tex]

The fourth option is the answer. When graphed, Min is 2, Q1 is 3, Median is 7, Q3 is 11, and Max is 24. The fourth option is the one that follow all of those!

Answer:

(D)

Step-by-step explanation:

The given data set is:

10, 12, 2, 4, 24, 2, 7, 7, 9

Firstly arrange the given data set in ascending order, we get

2, 2, 4, 7, 7, 9, 10, 12, 24

Now, the median of the above given data set is:

Step-by-step explanation:

All three sides of an equilateral triangle equals 60° each.

Given that the circles are equal and are inscribed in a triangle, the angle bisectors pass right through the center of the circle present in front of that angle.

For example a figure has been attached with the answer, where angle bisectors make a triangle with center of the circle and a perpendicular projection of the center on side AB.

Finding AB:

Let us divide the side AB into three parts. One is the line joining the center of the two circles which is = 2

Then we have two equal parts, each joining one vertices with the center of the circle.

Let us assume that there is a point P on the side AB which forms a line segment PO₁ ⊥ AB.

We have the right angled triangle APO₁. Angle A = 30°    PO₁ = r

let the base AP = x

We know that tan 30° = perp/base

1/√3 = r/x

=> x = √3  r

Hence Side AB = √3  r + 2r + √3  r

AB = (2+2√3)r

The volume of a sphere with a diameter of 9 inches, using 3.14 for pi, is calculated using the formula V = (4/3)πr³. The radius is 4.5 inches, leading to a volume of 381.675 cubic inches, which rounded to the nearest tenth is 381.7 cubic inches.

The question is asking for the volume of a sphere with a diameter of 9 inches, using 3.14 for pi. To find the volume, we first need to calculate the sphere's radius. Since the diameter is 9 inches, the radius (which is half the diameter) is 4.5 inches. The formula for the volume of a sphere is V = (4/3)πr³. Substituting the radius into the formula, we get:

V = (4/3)(3.14)(4.5³) = (4/3)(3.14)(91.125) = 381.675 cubic inches. When rounded to the nearest tenth, the volume is 381.7 cubic inches.

For this case, we have by definition that, the median of a set of numbers is the average number in the set, after the numbers have been ordered from lowest to highest. If there is an even number in the set, the median is the average of the two middle numbers.

So, the given set is:

{4,5,5,6,10,11,12,13}

Since there are 8 numbers, the set is even. Then we find the average of the two numbers in the middle:

Answer: g(x)=(3)-x

to reflect across the y-axis is to change the x coordinate values to opposite of what it is originally. ie;

f(x)=(3)x Now for a reflection across y-axis

g(x)=(3)-x

Answer:

[tex]g(x)= 3^{-x}[/tex]

Step-by-step explanation:

Given parent function is  [tex]f(x)= 3^x[/tex]

we need to find a function that is a reflection across y axis

For f(x) , reflection across y axis

f(x)  becomes f(-x)

For reflection across x axis, we multiply negative sign with x

f(x)  becomes f(-x)

[tex]f(x)= 3^x[/tex] becomes  [tex]f(x)= 3^{-x}[/tex]

Replace f(x) with g(x)

[tex]g(x)= 3^{-x}[/tex]

[tex]g( - 2) = - 4[/tex]

[tex]g(5) = 5[/tex]

EXPLANATION

The given step function have constant y-values on certain interval.

To find g(2), we plug x=2 into

g(x) =3, because 2 belongs to the interval

2≤x<4

This implies that

[tex]g(2) = 3[/tex]

To find g(-2), we substitute x=-2 into g(x)=-4, because x=-4 belongs to

-3≤x<-1

This implies that,

[tex]g( - 2) = - 4[/tex]

Similarly,

[tex]g(5) = 5[/tex]

because x=5 belongs to the interval,x≥4

Answer:

g(2)=3,

g(-2)=-4,

g(5)=5

Step-by-step explanation:

g(2) means find the value of function g(x) when x=2

from given restriction we see that x=2 lies withing [tex]2 \leq x <4[/tex]

corresponding function value is 3

Hence g(2)=3

-------

g(-2) means find the value of function g(x) when x=-2

from given restriction we see that x=-2 lies withing [tex]-3 \leq x <-1[/tex]

corresponding function value is -4

Hence g(-2)=-4

-------

g(5) means find the value of function g(x) when x=5

from given restriction we see that x=5 lies withing [tex]x \geq 4[/tex]

To change the mixed expression into a fraction, rewrite the mixed number as an improper fraction. Find the common denominator and combine the fractions by subtracting the second fraction from the first fraction.

To change the mixed expression into a fraction, we need to first rewrite the mixed number as an improper fraction.

The mixed number y-1 can be written as (y-1)/1.

Then, we can rewrite the expression as ((y-1)/1) - (5/(y+3)).

To combine these fractions, we need to find a common denominator.

The common denominator is (y+3), so we need to multiply the first fraction by (y+3)/(y+3) and the second fraction by 1/1.

This gives us ((y-1)(y+3))/((y+3)(1)) - (5/(y+3)).

Now, we can combine the fractions by subtracting the second fraction from the first fraction.

This gives us (((y-1)(y+3))-5)/(y+3).

Final answer:

To change the mixed expression into a fraction, find a common denominator and simplify the expression.

Explanation:

To change the mixed expression into a fraction, we need to find a common denominator.

The common denominator for the given expression y-1 and 5/y+3 is (y+3). To convert y-1 to have the common denominator, we multiply the numerator and denominator by (y+3), resulting in (y+3)(y-1)/(y+3). Next, we can simplify the expression by multiplying out the numerator and combining like terms. The final fraction is (y² + 2y - 3)/(y+3).

The point (1,16) is on the graph of g(x), hence it must satisfy its equation:

This implies that,

[tex]a {(1)}^{2} = 16[/tex]

[tex]a = 16[/tex]

We substitute the value of 'a' to get,

[tex]g(x) = 16 {x}^{2} [/tex]
