Answer:
[tex]g(h(-8)) = 119[/tex]
Hence, option B) is true.
Step-by-step explanation:
Given
g(x) = 2x-5
h(x) = x² - 2
To determine
[tex]g(h(-8)) = ?[/tex]
In order to determine g(h(-8)), first we need to determine h(-8), so
substituting x = -8 in h(x) = x² - 2
h(x) = x² - 2
h(-8) = (-8)² - 2
h(-8) = 64 - 2
h(-8) = 62
so we can write
[tex]g(h(-8)) = g(62)[/tex]
now, to determine g(62), substitute x = 62 in g(x) = 2x-5v
g(x) = 2x-5
g(62) = 2(62) - 5
g(62) = 124 - 5
g(62) = 119
so,
[tex]g(h(-8)) = g(62)=119[/tex]
Therefore,
[tex]g(h(-8)) = 119[/tex]
Hence, option B) is true.

An airplane climbs at an angle of
16° with the ground. Find the
ground distance the plane travels
as it moves 2500 m through the
air.
Help me
Answer:
[tex]2403\:\mathrm{m}[/tex]
Step-by-step explanation:
We can form a right triangle and use trigonometry for a right triangle to solve this. The ground distance the plane travels is its displacement in the x-direction. The 2500 meters the plane moves through represents the hypotenuse of right triangle, and the ground distance is the adjacent leg of the [tex]16^{\circ}[/tex] angle. Therefore, we set up the following equation:
[tex]\cos 16^{\circ}=\frac{x}{2500}[/tex], where [tex]x[/tex] is the ground distance.
Solving, we get [tex]x=2500\cdot \cos 16^{\circ} \approx \fbox{$2403\:\mathrm{m}$}[/tex].

The function family is exponential when separating the denominator out of numerator.
Exponential family have the equation of
[tex]y = {a}^{x} [/tex]
Denominator
[tex]y = x[/tex]
The function family is linear when separating the numerator. The equation for linear family is only
[tex]y = mx + b[/tex]
We combine both exponential and linear by dividing the exponential with linear.
AnswerWe divide the exponential function by a linear function.Can someone please answer quick there’s a math test and I only have one minute to answer this question please it’s my last question.
Answer:
The equation of the line in slope-intercept form is:
y = 3/5x + 5
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptTaking two points
(-5, 2)(5, 8)Taking two points (-5, 2) and (5, 8) to determine the slope
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-5,\:2\right),\:\left(x_2,\:y_2\right)=\left(5,\:8\right)[/tex]
[tex]m=\frac{8-2}{5-\left(-5\right)}[/tex]
Refine
[tex]m=\frac{3}{5}[/tex]
We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = 5
Thus, the y-intercept b = 5
now, substituting b = 5 and m = 3/5 in the slope-intercept form of the line equation
y = mx+b
y = 3/5x + 5
Therefore, the equation of the line in slope-intercept form is:
y = 3/5x + 5
An 8 ft tall tent standing next to a man casts a 16 ft shadow. If the man is 6 ft tall, then how long is his shadow?
Answer:
The man's shadow is 12 feet long.
Step-by-step explanation:
In this question, we are given that an 8 foot tall tent casts a 16 foot shadow, and we are asked the calculate the length of the shadow a 6 foot tall man casts.
To solve this problem, find the relationship between 8 and 16- 16 is twice as much as 8, as 8 x 2 = 16.
From this we have: "The shadow of an object is twice as long as the object."
We can use this to calculate the length of the shadow for a 6 foot tall man. Since the height of the man is 6 feet, the length of his shadow would be 12 feet.

Answer:
a) 94°
Step-by-step explanation:
shape is a 5-sided polygon, known as a pentagon
number of degrees inside can be found by taking the number of sides (5), deducting 2 (3) and then multiplying by 180°.
Therefore there are 540° altogether.
add all like terms for all five angles: 24x - 12 = 540
24x = 552
x = 23
m∡P = 4(23) = 2
= 92 + 2

Alanna tried to solve an equation step by step. \begin{aligned} 4c&=12\\\\ \dfrac{4c}{4}&=12\cdot4&\green{\text{Step } 1}\\\\ c&=48&\blue{\text{Step } 2} \end{aligned} 4c 4 4c c =12 =12⋅4 =48 Step 1 Step 2 Find Alanna's mistake.
Answer:
Her mistake was in step 1
Step-by-step explanation:
Given the expression solved by Alanna
4c = 12
To get c, we will divide both sides of the equation by 4:
4c/4 = 12/4
c = 12/4
c = 3
Alanna made mistake in step 1 where she divided multiplied the right hand side of the equation by 4 instead of dividing by 4

Hazelhas$100inasavingsaccountthatearns10%interestperyear.Theinterestisnotcompounded.Howmuchwillshehavein1year? Use the formula i = prt, where i is the interest earned, p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.
Answer: See explanation
Step-by-step explanation:
Interest = PRT
Principal = $100
Rate = 10%
Time = 1 year
Interest = PRT = (100 × 10% × 1)
= 100 × 0.1 × 1
Interest = $10
Amount = Principal + Interest
= $100 + $10
= $110

What is the circle?A circle is a two-dimensional figure formed by a set of points that are at a constant or at a fixed distance (radius) from a fixed point (center) on the plane. The fixed point is called the origin or center of the circle and the fixed distance of the points from the origin is called the radius.
Radius of a circle is the distance from the center of the circle to any point on it's circumference.
Here, SM=OM=7.4 units
Therefore, option B is the correct answer.

Aiden cuts a ball of string into 14 equal pieces. The length of each piece of string is 2 1/4 yards. What is the original length of the ball of string?
Answer:
31 1/2 yards
Step-by-step explanation:
In order to calculate the original length of the ball of string we simply need to multiply the length of each piece of string by the total number of strings that were produced from the original ball of string. First, we can turn the 2 1/4 into a single decimal number. Since 1/4 is equal to 0.25 we just add this to 2 to get 2.25, now we can go ahead and multiply this by the 14 total pieces.
2.25 * 14 = 31.5 or 31 1/2 yards
