Answer:  

The initial velocity of the runner was 6 m/s, and the runner stopped after 8 seconds.

Step-by-step explanation:

We are given a graph that shows the velocity f(t) of a runner during a certain time interval.

From the graph it can be seen that , at time 0, the velocity  of the runner = 6m/s.

Hence, the initial velocity of the runner = 6 m/s

Also, the graph stops after time = 8 seconds.

It implies the runner stopped after 8 seconds.

Hence, the statement which describes the intercepts on the graph is :

"The initial velocity of the runner was 6 m/s, and the runner stopped after 8 seconds."

Mary wants to buy a new house but needs money for the down payment. Her parents agree to lend her money at an annual rate of 2%,
lukranit [14]

Answer:

a) Simple interest paid = $360

b) Total repayment amount = $6360

Step-by-step explanation:

It is given that:

Principal, P = $6000

Rate of interest, R = 2%

Time, T = 3 years

<em>(a) Total interest paid</em>:

<u>Formula</u> for Simple Interest is given as:

S.I. = \dfrac{P \times R \times T}{100}

Putting the values of P, R and T to find out Simple Interest:\\\Rightarrow S.I. = \dfrac{6000 \times 2 \times 3}{100}\\\Rightarrow S.I. = \$360

<em>(b) Total repayment amount</em>:

We know that formula for total amount is given as:

<em>Amount = Principal + Simple Interest</em>

Amount = 6000 + 360 = $6360

So, total repayment amount = $6360

So, the answers are:

a) Simple interest paid = $360

b) Total repayment amount = $6360

I need help working question 8. I don't understand how to start it
Lina20 [59]
Why don't you first try to use the cosine law to solve for an angle and then make use of the sin law to solve for the remaining angles.

Cosine law

C^2 = A^2 + B^2 - 2AB(cos C)
Solve for cos C, and then take the inverse of the trig ratio to solve for the angle.

Then set up a proportion like you have done using the sin law and solve for another angle. Knowing the sum of all angles in a triangle add up to 180 degrees, we can easily solve for the remaining angle.

How to find MP when discount percent and SP are given​
nadezda [96]

Given:

Consider the discount percent and SP are given​.

To find:

The MP.

Solution:

Let x% be the discount percent Then

SP=MP-x\%\text{ of }MP

SP=MP-\dfrac{x}{100}MP

SP=\left(1-\dfrac{x}{100}\right)MP

SP=\left(\dfrac{100-x}{100}\right)MP

Multiply both sides by 100.

100SP=(100-x)MP

Divide both sides by (100-x).

\dfrac{100}{100-x}SP=MP

Therefore, the formula for MP is MP=\dfrac{100}{100-x}SP, where x is the discount percentage.
