Given:
The cost of the T.V. for Colin = £ 800.
The rate of depreciation per year = 4%
Time period = 3 years
To find:
How much will it be worth in 3 years? Give your answer to the nearest penny where appropriate.
Solution:
To solve the above-given problem, we will use the following formula:
where
A = the final value after depreciation
P = the present value
R = rate of depreciation
n = time period
Now, on substituting the given values in the formula, we get
we will round the above answer to its nearest penny where appropriate
≈ £ 708
Thus, the worth of the t.v. in 3 years will be £ 708.

A model rocket was launched from a podium 5 meters above are
an initial velocity of 98 m/s. The function that models height in me
with respect to time (in seconds) is h(t) = 5 + 987-4.9t2
meters above ground at
meters)
Answer:
See solution belowStep-by-step explanation:
Find the complete question below;
Given the height modeled by the function;
h(t) = 5 + 98t-4.9t²
when t = 0
h(0) = 5 + 98(0)-4.9(0)²
h(0) = 5
when t = 5
h(5) = 5 + 98(5)-4.9(5)²
h(5) = 5 + 490 - 122.5
h(5) = 372.5
when t = 10
h(10) = 5 + 98(10)-4.9(10)²
h(10) = 5 + 980 - 490
h(10) = 495
when t = 15
h(15) = 5 + 98(15)-4.9(15)²
h(15) = 5 + 1470 - 1,102.5
h(15) = 372.5
when t = 20
h(10) = 5 + 98(20)-4.9(20)²
h(10) = 5 + 1960 - 4.9(400)
h(10) = 1965- 1960
h(10) = 5

Answer:
C, B
Step-by-step explanation:
Basically to find the slope you take the rise over run. How many squares does the line go up, over how many does it go left or right. As you can see in the diagram, it goes up 2 squares and goes left 1 square, giving the slope 2/1, which is 2.
The slope of a horizontal line is straight, which means it goes up 0, so automatically your answer is zero, because dividing anything by 0 is 0.

What is the number system?A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9.
As per option (A),
4 x 10⁵
This number is not a square number.
As per option (B),
9 x 10⁴ = (3² x 10²)²
This number is a square number.
As per option (C),
4 x 10³
This number is not a square number.
As per option (D),
9 x 10³
This number is not a square number.
Thus, the number 9 x 10⁴ is a square number.

13.5 cm
A
B
Answer:
AB ≈ 8.86 cm
Step-by-step explanation:
Using the sine ratio in the right triangle
sin41° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{AB}{13.5}[/tex] ( multiply both sides by 13.5 )
13.5 × sin41° = AB , then
AB ≈ 8,86 cm ( to 3 significant figures )
Answer:
8.87
Step-by-step explanation:
use the sin law for right triagles sin(θ)= opposite/hypotenuse so
sin(41)=(AB)/13.5
13.5×sin(41)=AB
8.87=AB

Kelsey knit a total of 6 centimeters of scarf over 2 nights. After 4 nights of knitting, how many centimeters of scarf will Kelsey have knit in total? Assume the relationship is directly proportional.
Answer:
[tex]12[/tex] cm
Step-by-step explanation:
If Kelsey knit a total of [tex]6[/tex] cm of scarf over [tex]2[/tex] nights, then we know that she can knit [tex]\frac{6}{2}=3[/tex] cm each night. Therefore, after [tex]4[/tex] nights of knitting, Kelsey would have knit a total of [tex]3*4=12[/tex] cm of scarf in total. Hope this helps!

Answer:
radius=6
Step-by-step explanation:
arc ACB=6xPi
Pi=3.14159
arc ACB=18.85 (rounded to 2 places)
ACB is a half circle so a full circle would be 18.85x2 or 37.7
circumference (whole circle)=2 x Pi x radius
37.7=2 x 3.14159 x radius
radius= 37.7/(2 x 3.14159)
radius=6
Olivia wants to know the proportion of students at her school who use a
certain social media app. She interviews a random sample of students at
her school. She finds that 30% of the students in the sample use the app.
What conclusion can she draw from the sample?
А
It is likely that about 30% of the students at her school use the app.
B Exactly 30% of the students at her school use the app.
Every random sample would find that 30% of the students use
the app
It is likely that 30% of the students at her school were selected for
the sample.
Answer:
A
Step-by-step explanation:
Random sampling is a sampling method where each sample has an equal chance of being chosen. The random sample chosen is meant to be an unbiased representation of the population.
If 30% of the sample uses the app, it means that 30% of the population are likely to use the app

5.02 Which equation does the graph below represents?
1. y = -1/2x
2. y = -2x
3. y = 1/2x
4. y = 2x
Answer:
2. y= -2x
Step-by-step explanation:
When the line is on an exact point like it is on (-4, 8), we can simplify it by going rise/run
Rise is the same as y (8), and your run is x (-4)
When you divide 8/-4, your answer will be -2
Therefore, the answer is y= -2x
