Answers
Answer and Step-by-step explanation:
Trigonometric Function (These only work for right triangles):
SOH-CAH-TOA
S = Sine = sin
C = Cosine = cos
T = Tangent = tan
O = Opposite (side)
H = Hypotenuse (side)
A = Adjacent (side)
SOH = sin(angle) = [tex]\frac{opposite}{hypotenuse}[/tex]
CAH = cos(angle) = [tex]\frac{adjacent}{hypotenuse}[/tex]
TOA = tan(angle) = [tex]\frac{opposite}{adjacent}[/tex]
1. sinQ (Q is the angle) = [tex]\frac{14}{50} = \frac{7}{25} = 0.28[/tex]
Use Pythagorean Theorem to find side PQ. [tex]14^{2} + PQ^{2}= 50^{2} \\PQ^{2} = 2304\\PQ = 48[/tex]
2. cosQ = [tex]\frac{48}{50} = \frac{24}{25} = 0.96[/tex]
3. tanQ = [tex]\frac{14}{48} = \frac{7}{24} = 0.29[/tex]

Answer:
they intercept at (2,39)
Step-by-step explanation:
so, the starting point is the y int, and the rate it warms up is the slope so you need to create an equation that follows y=mx+b, then you can use a graphing calculator like desmos, to graph the equation.
the equations would be y=11x+17 and 8x+23, x represents hours.

Step-by-step explanation:
Joanna is driving 185 miles to visit her family. She drives 68 miles in the morning, stops for lunch, and then drives the rest of the distance. How many miles did she drive after lunch?
Use the variable m to represent the number of miles she drove after lunch.
Which equation represents this situation and its solution?
m + 68 = 185; m = 117
68m = 185; m = 17
m + 185 = 68; m = 117
185m = 68; m = 17
Answers
Answer:
The equation represents this situation and its solution are m + 68 = 185; m = 117 ⇒ A
Step-by-step explanation:
Let us solve the question
∵ Joanna is driving 185 miles to visit her family
∴ The total distance she is driving = 185 miles
∵ She drives 68 miles in the morning
∴ d[tex]_{M}[/tex] = 68 miles
∵ She stops for lunch and then drives the rest of the distance
∵ m represents the number of miles she drove after lunch
∴ d[tex]_{L}[/tex] = m miles
∵ d[tex]_{L}[/tex] + d[tex]_{M}[/tex] = the total distance she is driving
∴ m + 68 = the total distance she is driving
∵ The total distance she is driving = 185 miles
∴ m + 68 = 185
∴ The equation represents this situation is m + 68 = 185
→ To solve the equation subtract 68 from both sides
∵ 68 - 68 + m = 185 - 68
∴ m = 117 miles
∴ The solution is m = 117

Answers
Answer:
Step-by-step explanation:
the top one... which is I am assuming asking for the diameter?
Formula = d=2r
so 2x4 which is 8
But if you were wanting number 6
the formula is A=πr2
which would be 3.14 x 1^1 = 3.14
you take the diameter and square it and then multiply it by pi

A car travels 72 miles on 6 gallons of gas. At that rate, how much gas will it need to travel 204 miles?
Answers
Answer:
17 gallons
Step-by-step explanation:
First find how many miles it can travel with 1 gallon which would be 72÷6 = 12 So 1 gallon can takes it to 12 miles
Do 204÷ 12 = 17
Answer:
17 galloons
Step-by-step explanation:
72 Miles= 6 galloons
144 miles = 12 galloons
204 miles = 17 galloons
in every 12 miles is equivalent to 1 galloon of gas so basically when you divide 204 into 12 you will get 17. you need 17 galloons of gas

Step-by-step explanation:
list the integers that satisfy both these inequalities, 2x+9 <-12
Subtract 9 from both sides;
2x +9 - 9 < -12-9
2x < -21
x < -21/2
x < -10.5

C.8(1/3x1/2)
D.(8x1/3)1/2

= [8 * (1/2)] * (1/3)
= 4 * (1/3)
= 4/3.
The answer is B because it is easier to calculate 8 * (1/2), which is dividing 8 by 2 to get 4.
