If a sports car is traveling at 95 miles per hour, how long would it take the sports car to overtake a family car traveling at 35 miles per hour that left the same starting point 4.5 hours earlier?

Answers

Answer 1
distance = speed * time
d = st

The sports car travels d distance for t time at speed, s, 95 mph until it overtakes the family
car.
The equation for the sports car is
d = 95t

The family car travels the same distance, d, but since it left 4.5 hours earlier  than the sports car, it travels for t + 4.5 time until it is overtaken. It travels at speed, 35 mph.
The equation for the family car is
d = 35(t + 4.5)

We solve the two equations as a system of equations.

d = 95t
d = 35(t + 4.5)

Since d = d, set the right sides of the equations above equal to each other.

95t = 35(t + 4.5)

95t = 35t + 157.5

60t = 157.5

t = 2.625

The answer is 2.625 hours, or 2 hours, 37 minutes, and 30 seconds.

Check:
In 2.625 hours, the sports car travels: 95 mph * 2.625 h = 249.375 miles
The family car traveled 2.625 hours plus the extra 4.5 hours, or 7.125 hours.
In 7.125 hours, the family car travels 35 mph * 7.125 h = 249.375 miles.
The cars have traveled the same distance 2.625 hours after the sports car left, so our answer is correct.

Problem 7

This is a 30-60-90 triangle. The short leg is half of the hypotenuse so 12/2 = 6 units long

The long leg, x, is equal to sqrt(3) times the short leg

long leg = (short leg)*sqrt(3)
long leg = (6)*sqrt(3)
long leg = 6*sqrt(3)

Answer: Choice B

=====================================================

Problem 8

This is a 45-45-90 triangle. The two legs are congruent. In this case, they are both 7*sqrt(2) units long. 

Hypotenuse = (leg)*sqrt(2)
Hypotenuse = (7*sqrt(2))*sqrt(2)
Hypotenuse = 7*(sqrt(2)*sqrt(2))
Hypotenuse = 7*sqrt(2*2)
Hypotenuse = 7*sqrt(4)
Hypotenuse = 7*2
Hypotenuse = 14

So the value of x is 14

=====================================================

Problem 9

Use the SAS area of a triangle rule

Area of triangle = 0.5*(side1)*(side2)*sin(included angle)
A = 0.5*(8)*(12)*sin(65)
A = 48*sin(65)
A = 43.5027737777591
A = 43.5

Answer: 43.5

=====================================================

Problem 10

Angle C is the included angle (aka the angle between the given sides). Like with problem 9, we use the SAS area rule

Area = 0.5*(side1)*(side2)*sin(included angle)
Area = 0.5*12*1.5*sin(63)
Area = 9*sin(63)
Area = 8.01905871769531
Area = 8.02

Answer: 8.02

Problem 12

D = Dino
G = Garret
M = Marco

Given Info:
DM = 17 yards
GM = 15 yards
angle M = 81 degrees

What we want to find: 
distance from D to G, aka the length of DG
Call this value x for now

Use the law of cosines to find x
(DG)^2 = (DM)^2 + (GM)^2 - 2*(DM)*(GM)*cos(M)
x^2 = 17^2 + 15^2 - 2*17*15*cos(81)
x^2 = 289 + 225 - 510*cos(81)
x^2 = 514 - 510*cos(81)
x^2 = 514 - 79.7815771705178
x^2 = 434.218422829482
sqrt(x^2) = sqrt(434.218422829482)
x = 20.8379083122439

Rounded to the nearest yard, the distance from Garret to Dino is roughly 21 yards.

What is Trigonometry?

Trigonometry is a discipline of mathematics that studies the relationship between the sides of a triangle (right triangle) and their angles. There are six trigonometric functions that define the relationship between sides and angles.

1. Using Trigonometry

sin 60 = P/H

√3/2 = x/ 12

x = 12√3 / 2

x= 6√3

2. Using Trigonometry

sin 60 = P/H

1/√2 = 7√2 / x

x/√2 = 7√2

x = 14 unit

3. Using sine law

sin 75 /11 = sin 54 / x

0.965 / 11 = 0.809 / x

0.0877 = 0.809 / x

x = 9.224 miles

which number is a solution of the inequality 12 < y(8-y)

Answers

The solution to the inequality 12 < y(8 - y) is y such that 2 < y < 6.

The solution of the inequality 12 < y(8 - y), you can start by simplifying the expression on the right side: y(8 - y)
Distribute the y on the right side: 8y - [tex]y^2[/tex]
Now, substitute this expression back into the original inequality: [tex]12 < 8y - y^2[/tex]
Rearrange the terms to form a quadratic inequality: [tex]y^2 - 8y + 12 > 0[/tex]

Now, factor the quadratic expression: (y - 2)(y - 6) > 0
To solve for y, set each factor equal to zero and find the critical points: y - 2 = 0 or y - 6 = 0
Solving these equations gives y = 2 and y = 6.

Now, create intervals using these critical points and test a value in each interval:
1. Test y = 1: (1 - 2)(1 - 6) = (-1)(-5) = 5 > 0
2. Test y = 3: (3 - 2)(3 - 6) = (1)(-3) = -3 < 0
3. Test y = 7: (7 - 2)(7 - 6) = (5)(1) = 5 > 0
The solution is y such that 2 < y < 6

An Uber driver carries riders to and from a local airport and a neighboring suburb. Due to traffic and the time of day the driver works, the trip to the airport takes 60 minutes longer than the trip to the suburb. The car’s average speed in traffic is 30 miles per hour. Without traffic, the car travels 15 miles per hour. The equation can be used to determine how many miles apart the two locations are shown. What is the value of m, the distances between the two locations?

A) 0.5 miles
B) 22.5 miles
C) 30 miles
D) 90 miles

Answers

Answer: Choice B) 22.5 miles

--------------------------------------------
--------------------------------------------

To find that answer, we simply solve for m

m/(30-15) = m/(30+15) + 1
m/15 = m/45 + 1
45*m/15 = 45*(m/45 + 1) ... multiply both sides by the LCD to clear out fractions
3m = 45*(m/45) + 45*(1)
3m = m+45
3m-m = m+45-m
2m = 45
2m/2 = 45/2
m = 45/2 <--- answer as a fraction
m = 22.5 <--- answer in decimal form

Write an algebraic expression that is equivalent to the expression cot(arctan x)

Answers

cosX/sinX [tan-¹X]
cos²x/sin²x = cot²x
recall cot²x = cosec²x - 1

The algebraic expression equivalent to cot(arctan x) is 1 / x, derived by recognizing that cot(θ) is the reciprocal of tan(θ), and tan(θ) = x for θ = tan-1(x)

To find an algebraic expression for cot(arctan x), let's follow a step-by-step transformation using trigonometric identities: cot(arctan x) is denoted as cot(tan-1(x))

First, let
θ = tan-1(x). By definition of the arctan function, we have the relation:tan(θ) = x.Next, we need to find cot(θ). Recall that:cot(θ) = 1 / tan(θ).Since tan(θ) = x, we substitute to get:cot(θ) = 1 / x .Thus, we have cot(tan-1(x)) = 1 / x.

Therefore, the algebraic expression equivalent to cot(tan-1(x)) is 1 / x.

Find the average rate of change for f(x) = x2 + 9x + 18 from x = −8 to x = −2.
A)−1
B)−3
C)1
D)3

Answers

In order to find the average rate of change, we must take the values at x=-8 and x= -2, and determine what the slope would be if a line was drawn between the two points. 
f(-8) = -8² +9(-8) + 18
f(-8) = 10

f(-2) = -2² + 9(-2) + 18
f(-2) =4 -18 +18
f(-2) = 4

f(-8) =10 and f(-2)=4

if a line was drawn between the two points (-8,10) and (-2,4) the slope (rise/run) would be -6/6, since the line would go down 6 units from 10 to 4, and over 6 units from x=-8 to x=-2.

The average rate of change, therefore, is -6/6, or

Using fractional exponent rule [tex]x^\frac{m}{n}=\sqrt[n]{x^m}[/tex], w ecan write our given number as:

[tex](\frac{750}{512})^{\frac{1}{3}}=\sqrt[3]{\frac{750}{512}}[/tex]

We can rewrite 512 as [tex]8^3[/tex] and 750 as 125*6.

[tex](\frac{750}{512})^{\frac{1}{3}}=\sqrt[3]{\frac{125*6}{8^3}}[/tex]

We can rewrite 125 as [tex]5^3[/tex]

[tex](\frac{750}{512})^{\frac{1}{3}}=\sqrt[3]{\frac{5^3*6}{8^3}}[/tex]

Using radical rule [tex]\sqrt[n]{a^n}=a[/tex], we will get:

[tex](\frac{750}{512})^{\frac{1}{3}}=\frac{5\sqrt[3]{6}}{8}[/tex]

Therefore, [tex]\frac{5\sqrt[3]{6}}{8}[/tex] is equivalent to our given number.

Hey there again!

First , let's add 17 on each of your sides (we have to get the "X" by itself , right?

Like: -12x - 17 + 17
= -89 + 17

So, divide by -12 on each of your sides since both numbers goes into 12

Like: 12x / -12 = -1

= -72 / -12 = 6

X = 6
