Using relations in a right triangle, it is found that the length of the zip line is of 40.4 feet.
What are the relations in a right triangle?The relations in a right triangle are given as follows:
The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.This situation can be modeled by a right triangle, in which the extension of the zip line of 48.2 feet is the hypotenuse and the length is the adjacent side to the angle of 33º, hence:
[tex]\cos{33^\circ} = \frac{l}{48.2}[/tex]
l = 48.2 x cos(33º)
l = 40.4.
The length of the zip line is of 40.4 feet.

The axis of symmetry for the graph of the function f(x)=3x2 bx 4 is x equals three-halves. what is the value of b? −18 −9 9 18
Using the vertex of the quadratic equation, it is found that the value of b is of -9.
What is the vertex of a quadratic equation?A quadratic equation is modeled by:
[tex]y = ax^2 + bx + c[/tex]
The vertex is given by:
[tex](x_v, y_v)[/tex]
In which:
[tex]x_v = -\frac{b}{2a}[/tex]
[tex]y_v = -\frac{b^2 - 4ac}{4a}[/tex]
The axis of symmetry is [tex]x = x_v = -\frac{b}{2a}[/tex].
Considering the coefficient a, we have that:
If a < 0, the vertex is a maximum point.If a > 0, the vertex is a minimum point.In this problem, we have that the function is defined as follows:
[tex]f(x) = 3x^2 + bx + 4[/tex]
We have that [tex]a = 3, x_v = \frac{3}{2}[/tex], hence the value of b is found as follows:
[tex]x = -\frac{b}{2a}[/tex]
[tex]\frac{3}{2} = -\frac{b}{6}[/tex]
b = -6 x 3/2
b = -9.

Consider the rectangle.
The x and y axes have a range from negative 7 to 7 in increments of 1. A rectangle is on the coordinate plane.
Which points could be the vertices of the image of the rectangle after it is dilated from the origin by a scale factor of 3? Select all that apply.
Answer:
Step-by-step explanation:
Dilating with a scale factor of 3 centered at the origin means we multiply all the coordinates by 3.
(0,2) maps onto (0,6).(0,4) maps onto (0,12).(3,2) maps onto (9,6).(3,4) maps onto (9,12).Therefore, the answers are the second option and the sixth option.

Answer:
Answer Choice A (8, eight)
Step-by-step explanation:
To begin, add all of the marbles together. When finished, the answer should be 20. Because the variable 20 equals 100, you divide 4 by 100. You will get 0.04 as a result. This multiplied by 20 equals 8. Finally, the answer is A.

The length GD, GE, and GF are the radius of the circle. Then GD = GE = GF is true. Thus, option A is correct.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.
The G is the intersection of the bisector lines. So, the G represents the center of the incircle.
The incircle will touch all three sides of the triangle. And the distance between the center of the circle to the sides of the triangle will be known as the radius and tangent to the circle.
Then we can write a condition for a circle. Then we have
GD = GE = GF = Radius
The length GD, GE, and GF are the radius of the circle. Then GD = GE = GF is true. Thus, option A is correct.

Probability helps us to know the chances of an event occurring. The probability of two cards being black without replacement is 24.5%.
What is Probability?Probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
Given the standard deck has 26 black cards while the total number of cards is 52. Therefore, the probability of two cards being black without replacement is,
Probability = (Probability of the first card is black) × (Probability of the second card being black)
Probability = (26/52) × (25/51)
Probability = 0.245 = 24.5%
Hence, the probability of two cards being black without replacement is 24.5%.

First of all, parallel lines have the exact same slope.
So we know the slope of the line:- -5.
(enter -5, It's the number that belongs in the green box)
How about the y-intercept?
Well, since we're given the slope and a point that the line intersects, we can write the line's equation in point-slope form:-
y-y1=m(x-x1)
y-(-3)=-5(x-(-3)
y+3=-5(x+3)
y+3=-5x-15
y=-5x-18

The equation of line which is parallel to y= -5x - 9 is y=-5x-18.
What is equation of line?The general equation of a straight line is y = mx + c, where m is the gradient, and y = c is the value where the line cuts the y-axis.
Given:
y= -5x - 9 passes the point (-3, -3)
As, the slope of parallel lines are
m1 = m2 = -5
Now, if the point (-3, -3) intersects the line then equation in point-slope form is
y-y1=m(x-x1)
y-(-3)=-5(x-(-3)
y+3=-5(x+3)
y+3=-5x-15
y=-5x-18
Hence, the equation of line is y=-5x-18

Tyrell has a bankruptcy on his credit report and therefore pays higher interest rates on his current loans. he calculates that the extra money he pays in additional interest each year, if invested at the rate of 2.5% for one year, could earn him simple interest totaling $300. how much does tyrell pay in additional interest each month? a. $90 b. $100 c. $1,000 d. $12,000 please select the best answer from the choices provided. a b c d
Based on the simple interest amount he could be making, and the rate of investment, Tyrell's additional interest per month is $1,000.
How much is Tyrell paying in additional interest?Assuming the additional interest that Tyrell is paying is x, the following formula can be used:
300 = (x × 2.5%) x 12 months
Solving gives:
300 = 0.025x × 12

5. a) Among 72 students, 24 are selected to participate in music only, 26 are selected to participate in dance only and none of them participated in both activities. The rest of the students are selected in other activities. (i) How many students are participating in other than music or dance?
Answer
The students participating in other than music or dance = 22
Step by step explanation
Total number of students = 72
No. of students participating in dance = 26 (let them be 'a')
No. of students participating in music = 24 (let them be 'b')
No. of students participating in othe na than dance or music = 'c'
72 = a+b+c
= 26+24+c
= 50 + c
c (no. of students participating in other activities)
= 72 - 50 = 22

Step-by-step explanation:
6 x 16.98 = 101.88

Step-by-step explanation:
6×$16.98=$101.88=cost of basketballs
6×$13.79=$82.74=cost of soccer balls
cost of basketballs + cost of soccer balls = total cost
$101.88+$82.74=$184.62
