Derek's car has run out of gasoline. He walks 24 km west and then 10 km south looking for a gasoline station. If he is now h km directly from his starting point, find the value of h
Answers
Answer:
the value of h is √676km
Step-by-step explanation:
The computation of the value of h is shown below
Here we apply the Pythagoreus theorem
= 24^2 + 10^2
= 576 + 100
= √676
Hence, the value of h is √676km
We simply determine by using the Pythagoreus theorem

A new laptop costs $1100 and has a new book value of $375 after 2 years. Find the linear model V(t)=Mx+b
Answers
Answer:
- 362.5t + 1100
Step-by-step explanation:
Given :
Value, = v ; time, = t
t1, v1 = (0, 1100)
t2, v2 = (2, 375)
Slope, m = v2 - v1 / t2 - t1
m = (375 - 1100) / (2 - 0)
m = - 725 / 2
m = - 362.5
v - v1 = m(t - t1)
v - 1100 = - 362.5(t - 0)
v - 1100 = - 362.5t
v = - 362.5t + 1100

Jacob is planting flowers in his yard. He goes to a nursery to purchase flowers, and he decides to purchase petunias and sunflowers. Each petunia plant costs $2.99 with tax, and each sunflower plant costs $2.79 with tax. Jacob has $43.85 to purchase the flowers. If he buys 10 petunia plants, which inequality can be used to find s, the number of sunflower plants that Jacob can purchase?
A.
10($2.99) + $2.79s < $43.85
B.
10($2.99) + $2.79s > $43.85

A stock can go up, go down, or stay unchanged. How many possibilities are there if you own 3 stocks?
Answers
Answer:
There are 27 different possible outcomes.
Step-by-step explanation:
Assuming that you have 3 different stocks:
First, we need to find the number of events and the number of possible outcomes for each event.
Here we can assume that each one of the stocks is a event, and the number of possible outcomes for each one are:
Stock 1: 3 options (up, down, stay)
Stock 2: 3 options (up, down, stay)
Stock 3: 3 options (up, down, stay)
The total number of possible outcomes is equal to the product of the numbers of options for all the events.
Then the total number of possibilities is:
C = 3*3*3 = 27

A ball is dropped from a height of 20 feet. It hits the ground and bounces up half as high as it fell. This is true for each successive bounce. What height does the ball reach on the fourth bounce
Answers
Answer:
1.25 m
Step-by-step explanation:
Given that :
Initial height of drop = 20 meters
Rebound after each drop = 1/2 of height
Height after 4th rebound = 5th term of a geometric series
An = a1 * r^(n-1)
a1 = first term = initial drop height
r = common ratio = ratio of rebound per drop = 1/2 = 0.5
A5 = 20 * 0.5^(5 - 1)
A5 = 20 * 0.5^4
A5 = 20 * 0.0625
A5 = 1.25 m
Hence height after 4 reboubd = 1.25 m
Using another method :
1st bounce height = 20 * 0.5 = 10
2nd bounce height = 10 * 0.5 = 5
3rd bounce height = 5 * 0.5 = 2.5
4th bounce height = 2.5 * 0.5 = 1.25

Answers
Answer:
g(0) = -2
Step-by-step explanation:
Given - g(x) = -x - 2
To find - g(0)
Proof -
We have given the function ,
g(x) = -x - 2
For finding the value of g(0), we just have to put x = 0 in g(x),
We get
g(0) = -0 - 2 = -2
⇒g(0) = -2
