2. A scuba diver dove 48 feet in 4 minutes.
What integer represents his change in depth
for each minute?
A. 52 feet per minute
B. 44 feet per minute
C. -12 feet
per
minute
D. -48 feet per minute
Answer:
C. -12 feet per minute
Step-by-step explanation:
This question is really just asking for the slope of this situation. So the best way to find the answer is to find the change in y over the change in x. In this case, y is the depth and x is the time. So, it would be -48/4 because the diver went down 48 feet when 4 minutes passed. Then, simply divide, -48/4, which equals -12 feet/1 minute.

In ANOP, NP is extended through point P to point Q, m_OPQ = (9x – 19)°,
mZPNO = (2x + 5), and mZNOP = (3x + 16º. Find mZNOP.
Answer:
The values of x and y are x = 6 and y = 9Step-by-step explanation:
MNOP is a parallelogram its diagonal MO and PN intersected at point A
In any parallelogram diagonals:
Bisect each other
Meet each other at their mid-point
In parallelogram MNOP
∵ MO and NP are its diagonal
∵ MO intersect NP at point A
- Point A is the mid-point pf them
∴ MO and NP bisect each other
∴ MA = AO
∴ PA = AN
∵ MA = x + 5
∵ AO = y + 2
- Equate them
∴ x + 5 = y + 2 ⇒ (1)
∵ PA = 3x
∵ AN = 2y
- Equate them
∴ 2y = 3x
- Divide both sides by 2
∴ y = 1.5x ⇒ (2)
Now we have a system of equations to solve it
Substitute y in equation (1) by equation (2)
∴ x + 5 = 1.5x + 2
- Subtract 1.5x from both sides
∴ - 0.5x + 5 = 2
- Subtract 5 from both sides
∴ - 0.5x = -3
- Divide both sides by - 0.5
∴ x = 6
- Substitute the value of x in equation (2) to find y
∵ y = 1.5(6)
∴ y = 9
The values of x and y are x = 6 and y = 9
ABCD is a parallelogram.Find angle CBD.
9514 1404 393
Answer:
81°
Step-by-step explanation:
Opposite angles of a parallelogram are congruent. The sum of the two angles at B is the same as the value marked at D.
∠CBD = 139° -58° = 81°
_____
Additional comment
The angles at A and C are both 41°, the supplement of the one marked 139°.

A right triangle has side lengths 7, 24, and 25 as shown below.
Use these lengths to find tanA, sinA, and cosA.
9514 1404 393
Answer:
tan(A) = 7/24sin(A) = 7/25cos(A) = 24/25Step-by-step explanation:
The mnemonic SOH CAH TOA can help you remember the trig ratios:
Sin = Opposite/Hypotenuse
Cos = Adjacent/Hypotenuse
Tan = Opposite/Adjacent
With respect to angle A, the sides are Adjacent = 24; Opposite = 7, Hypotenuse = 25. Then the desired trig ratios are ...
tan(A) = 7/24
sin(A) = 7/25
cos(A) = 24/25

Let 0 be an angle in quadrant 3 such that cos0=-5/13.
Find the exact values of csc0 and tan0
Answer:
see explanation
Step-by-step explanation:
Given
cosθ = - [tex]\frac{5}{13}[/tex]
This is a 5- 12- 13 right triangle
with adjacent = 5, opposite = 12 and hypotenuse = 13
In quadrant 3
sinθ < 0 and tanθ > 0 , then
sinθ = [tex]\frac{opposite}{hypotenuse}[/tex] = - [tex]\frac{12}{13}[/tex] and
cscθ = [tex]\frac{1}{sin0}[/tex] = [tex]\frac{1}{-\frac{12}{13} }[/tex] = - [tex]\frac{13}{12}[/tex]
then
tanθ = [tex]\frac{sin0}{cos0}[/tex] = [tex]\frac{-\frac{12}{13} }{-\frac{5}{13} }[/tex] = - [tex]\frac{12}{13}[/tex] × - [tex]\frac{13}{5}[/tex] = [tex]\frac{12}{5}[/tex]

Explain how to determine whether the difference of two numbers is less than or greater than the first number.
Answer:
To determine if the difference of two numbers is less or greater than the first number, check the value of the first number, and the value of the second number.
(greater) - (lesser) = (positive)
(lesser) - (greater) = (negative)
(neg lesser) - (neg greater) = (positive)
(neg greater) - (neg lesser) = (negative)
For Example:
10 - 5 = 5
5 - 10 = -5
(-5) - (-10) = 5
(-10) - (-5) = -5
