Answer:
Option C
Step-by-step explanation:
we know that
Two angles are complements if their sum is equal to 90 degrees
we have that
∠SWT=50°
so
Its complement must be equal to 40 degrees
we know that
∠USP=40°
∠TSV=40°
therefore
∠USP and ∠TSV are complements to ∠ SWT

ANSWER
[tex]g(2) = 3[/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]
corresponding function value is 5
Hence g(5)=5

Find the percent of change in altitude if a weather balloon moves from 50 ft to 95 ft. Describe the percent of change as an increase or decrease. Round to the nearest tenth if necessary.
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]
Percent of change in altitude = 90 %
Since the altitude increases from 50 ft to 95 ft the change is positive.

Write the ratio of corresponding sides for the similar triangles and reduce the ratio to lowest terms
answer is B) 3/9= 4/12 = 1/3
Answer:
the Ratio between the small and big triangles is that of b. [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
We can solve this ratio problem by using the Rate of Change formula as shown below,
[tex]\frac{y2-y1}{x2-x1}[/tex]
In this situation y would be the smaller triangle and x would be the larger triangle. Since all the values are given to use we can just plug those values in and solve for the rate of change / ratio.
[tex]\frac{4-3}{12-9} = \frac{1}{3}[/tex]
So the rate of change or ratio between the small and big triangles is that of [tex]\frac{1}{3}[/tex]

Answer:
C. [tex]N(t)=150\cdot 3^t[/tex]
Step-by-step explanation:
You are given the exponential function [tex]n(t)=ab^t.[/tex]
From the table, [tex]N(t)=150[/tex] at [tex]t=0,[/tex] thus
[tex]N(0)=a\cdot b^0\\ \\150=a\cdot 1\ [\text{ because }b^0=1][/tex]
Also [tex]N(t)=450[/tex] at [tex]t=1,[/tex] thus
[tex]N(1)=a\cdot b^1=a\cdot b.[/tex]
Since [tex]a=150,[/tex] substitute it into the second equation
[tex]450=150\cdot b\\ \\b=\dfrac{450}{150}\\ \\b=3[/tex]
and the expression for the exponential function is
[tex]N(t)=150\cdot 3^t[/tex]

So, you would reflect it over the y-axis first. (x,y)->(-x,y) and get A’ (1,2) B’ (2,6) C’ (4,4). Then, you rotate 90 degrees clockwise (x,y)->(y,-x). So, A”(2,-1) B” (6,-2) C” (4,-4). Hope this helps.
Answer:
Step-by-step explanation:
A(-1, 2), B(-2, 6), C(-4, 4)
You got the reflection part correct.
A'(-1, -2), B'(-2, -6), C'(-4, -4)
To rotate 90° clockwise, apply the following transformation:
A(x, y) = A(y, -x)

What is the length of the short leg in the 30-60-90 triangle shown below?
Answer:
Correct option is:
B. 5
Step-by-step explanation:
The triangle is a right angled triangle.
Let a be a angle adjacent to 90°
then, tana=Side opposite to angle a/Side adjacent to angle a which is not the hypotenuse
Here, Let a=60°
[tex]tan60\°=\dfrac{5\sqrt{3}}{Length\ of\ short\ leg}[/tex]
[tex]\sqrt{3}=\dfrac{5\sqrt{3}}{Length\ of\ short\ leg}[/tex]

true or false: the equation tan^2x+1=sec^2x
ANSWER
True
EXPLANATION
The given trigonometric equation is:
[tex] { \tan}^{2} x + 1 = { \sec}^{2} x[/tex]
We take the LHS and simplify to arrive at the RHS.
[tex]{ \tan}^{2} x + 1 = \frac{{ \sin}^{2} x}{{ \cos}^{2} x} + 1[/tex]
Collect LCM on the right hand side to get;
[tex]{ \tan}^{2} x + 1 = \frac{{ \sin}^{2} x + {\cos}^{2} x}{{ \cos}^{2} x} [/tex]
This implies that
[tex]{ \tan}^{2} x + 1 = \frac{1}{{ \cos}^{2} x} .[/tex]
[tex]{ \tan}^{2} x + 1 = {( \frac{1}{ \cos(x) }) }^{2} [/tex]
[tex]{ \tan}^{2} x + 1 = { \sec}^{2} x[/tex]
This identity has been verified .Therefore the correct answer is true.
Final answer:
The equation tan²(x) + 1 = sec²(x) is true and is derived from the fundamental Pythagorean trigonometric identity.
Explanation:
The statement tan²(x) + 1 = sec²(x) is true. This is based on a well-known trigonometric identity from mathematics.
In trigonometry, the Pythagorean identity for tangent and secant states that:
tan²(x) + 1 = sec²(x)
Which comes from the primary Pythagorean identity:
sin²(x) + cos²(x) = 1
by dividing each term by cos²(x) and recognizing that:
tan(x) = sin(x)/cos(x) and sec(x) = 1/cos(x).

Given: △ABC is equilateral. The radius of each circle is r.
Find AB
Answer:
AB = (2+2√3)r
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

Find the slope m of the line that passes through points (20, 66) and (30, 96)
The slope is 3/1 or 30/10.

You subtract 96 and 66 which equals 30. Then you subtract 30 and 20 which then equals 10. Then you simplify it which then equals 3/1
Freya is training for a track race. She starts by sprinting 200 yards. She gradually increases her distance, adding 5 years a day for 21 days. Which explicit formula models this situation?
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.
