If sin(21°) = 0.36, and cosθ = 0.36, what's the measure of ∠θ? ANSWERS: A) m∠θ = 21° B) m∠θ = 0.36° C) m∠θ = 90° D) m∠θ = 69°
Hey there! :)
Answer:
m∠θ = 69°.
Step-by-step explanation:
If sin (21°) = 0.36 and cos θ = 0.36, the two angles are complementary because the sine and cosine values are equivalent. Therefore:
90 - 21 = 69°.
The correct answer is D) m∠θ = 69°.
Suppose you pick and replace marbles from a bag, one after another. If the bag
contains 3 red marbles, 3 white marbles, and 6 blue marbles, what is the probability of
picking a red marble and then a blue marble?
Answer:
1/8
Step-by-step explanation:
There are 3 + 3 + 6 = 12 marbles in the bag and 12 * 12 = 144 ways to choose two marbles when replacing. There are 3 * 6 = 18 ways to choose a red marble and then a blue marble so the probability is 18 / 144 = 1 / 8.

The total cost of producing x units for which the fixed costs are $2500 and the cost per unit is $40
Step-by-step explanation:
45X + 2000 = Y
Where X = Number of units
Y = Total Cost
The total cost of producing x units for which the fixed costs are $2500 and the cost per unit is $40 is T(x) = 40x + 2500.

Answer:
the equation of the line in slope-intercept form is;
[tex]y=8x-26[/tex]
Step-by-step explanation:
First use the formula for the slope of the segment that joins the two given points:
[tex]slope=\frac{y_2-y_1}{x_2-x_1} =\frac{6-(-2)}{4-3}=\frac{8}{1} =8[/tex]
now that we have the slope, we can use the point-slope form of a line to find the line with slope 8 that passes through any of the given points, for example through (3, -2):
[tex]y-y_0=m\,(x-x_0)\\y-(-2)=8\,(x-3)\\y+2=8\,(x-3)\\y=8x-24-2\\y=8x-26[/tex]

What equation could be used to find the missing leg length a in a right triangle with a hypotenuse of 60 and leg length of 51?
Answer:
Pythagorean Theorem: a² + b² = c² should be used.

Hey there! :)
Answer:
Choice B.
Step-by-step explanation:
Since h(x) equals (g o f)(x):
f(x) is substituted for x in the equation g(x). We can go through the answer choices and choose the most suitable choice by substitution:
A. f(x) = x, g(x) = x/ x + 1
(g o f)(x) = x / x + 1. This is incorrect.
B. f(x) = x², g(x) = x / x + 1
(g o f)(x) = x² / x² + 1. This matches h(x), so this is correct.
C. f(x) = x + 1, g(x) = 1/x²
(g o f)(x) = 1/(x² + 2x + 1). This is incorrect.
D. f(x) = x + 1, g(x) = x²
(g o f)(x) = x² + 2x + 1. This is incorrect.
Therefore, B is the correct answer.
A rectangle is 1 inch longer than it is wide. Its diagonal is 5 inches. What's the width of the rectangle?
Answer:
Step-by-step explanation:
Let x be the length and y be the width
The length is 1 inch longer than the width
So : x-1 =y
●●●●●●●●●●●●●●●●●●
The diagonal is 5 inches
The diagonal, width and length are forming a right triangle where the diagonal is the hypotenus
The Pythagorian theorem:
x^2 + y^2 = 5^2
●●●●●●●●●●●●●●●●●●●●●●●
Let's calculate y the width
The system is :
x-1 = y => x =y+1
x^2 + y^2 = 25
Replace x in the second equation with y+1 :
(y+1)^2 + y^2 = 25
y^2 + 2y + 1 + y^2 = 25
2y^2 + 2y +1 = 25
2y^2 + 2y -24 = 0
This is a quadratic equation so we will use the discriminant
●●●●●●●●●●●●●●●●●●●●●●
the discriminat is b^2-4ac
● b =2
● a = 2
● c = -24
b^2 -4ac = 4-4*2(-24) =196 > 0
Since the dicriminant is positive this equation has two solutions y and y'
y = (-2-14)/4 = -16/4 = -4
y '= (-2+14)/4 = 12/4 = 3
The first solution is negative
A distance is always positive so the first solution can't be the width
Then the width is 3

What are the zeros of f(x) = x2 + x - 30?

B. x= -2 and x= 15
o
C. x= -5 and x = 6
D. x= -15 and x = 2
SS
Answer:
A
Step-by-step explanation:
The zeroes of the function are the x values when f(x) = 0 so we can write:
0 = x² + x - 30
0 = (x + 6)(x - 5) (To factor this we need to find 2 numbers that have a sum of 1 and a product of -30; these numbers are 6 and -5)
x + 6 = 0 or x - 5 = 0 (Use Zero Product Property)
x = -6, 5
Hey there! :)
Answer:
A. x = -6 and x = 5.
Step-by-step explanation:
Given:
f(x) = x² + x - 30
Factor the equation by finding two numbers that sum up to 1 and multiply into -30. We get:
-5, 6
Use these to express this quadratic function in factored form:
f(x) = (x - 5) (x + 6)
Set each factor equal to 0 to solve for the zeros of the equation:
0 = x - 5
x = 5
-------------
0 = x + 6
x = -6
Therefore, the correct answer is A. x = -6 and x = 5.

there are 1600 students in school.47.5% are male.how many are female
Answer:
840 female students
Step-by-step explanation:
The total percentage of students is 100%, so, the percentage of female students = 100% - 47.5%
=52.5%
Multiply the total no. of students by the percentage to get the no. of female students.
1600 x 52.5%
= 840 female students
You can also obtain the same answer by first multiplying the male percentage to find the no. of male students, then subtracting it from the total 1600.

Inverse matrix:
[tex]A^{-1} = \begin{pmatrix} \frac{1}{9} & \frac{2}{9} \\ \frac{1}{3} & -\frac{1}{3} \end{pmatrix} \quad[/tex]
Step-by-step explanation:
Determinant: ad - bc
a = 3, b = 2, c = 3, d = -1
3 * (-1) - (2 * x) = -9
-3 - 2x = -9
-2x = -6
x = 3
For matrix
[tex]A = \begin{pmatrix}a & b\\c & d\end{pmatrix} \quad[/tex]
the inverse is
[tex]A^{-1} = \dfrac{1}{ad - bc}\begin{pmatrix}d & -b \\-c & a\end{pmatrix}\quad[/tex]
Here we have: det = -9
a = 3, b = 2, c = 3, d = -1
Inverse matrix:
[tex]A^{-1} = \dfrac{1}{-9}\begin{pmatrix} -1 & -2 \\ -3 & 3 \end{pmatrix}\quad[/tex]
[tex]A^{-1} = \begin{pmatrix} \frac{-1}{-9} & \frac{-2}{-9} \\\frac{-3}{-9} & \frac{3}{-9}\end{pmatrix} \quad[/tex]
[tex]A^{-1} = \begin{pmatrix} \frac{1}{9} & \frac{2}{9} \\\frac{1}{3} & -\frac{1}{3}\end{pmatrix}\quad[/tex]
