Answer:

3¼

Step-by-step explanation:

$formula \frac{{y}^{2} - {y}^{1} }{ {x}^{2} - {x}^{1} }$

We take any of the two points shown in the question. I will take (-3, 1) and (1, 14).

x¹ = -3

y¹ = 1

x² = 1

y² = 14

Now, we sub these figures into the formula.

$\frac{14 - 1}{1 - ( - 3)}$

This leaves us with 14-1/1+3, which we can make into 13/4

13/4 = 3¼

Disclaimer: It is not actually x (or y) in the power of two, but a way to distinguish one x (or y) from the other. It is a label of sorts.

Q5. A car is bought for £5000 and sold for £7500. What is the percentage profit?

Nitella [24]

Answer:

50% profit

Step-by-step explanation:

Cost price = £ 5000

Selling price = £ 7500

Profit = Selling price - cost price

= 7500 - 5000

= £ 2500

Profit percentage = $\frac{2500}{5000}*100$

= 50 %

drek231 [11]

In the given situation, the ratio of the perimeters of two rectangles is 4 to 7. The perimeter of the larger rectangle is 42 inches.Now, let's find the perimeter of the smaller.Let's solve for the answerRatio and formula:=> 4 : 7 = X = 42, where x is the unknown perimeter of the smaller rectangle=> 4 * 42 = 168 / 7 = 24Thus the answer is letter D. 24 inches is the parameter of smaller rectangle.

Use the triangle below to find the following trig ratios. Express your answer as a fraction.

Luda [366]

Answer:

Step-by-step explanation:

First we need the length of the hypotenuse.

20^2 + 21^2 = c^2

400 + 441 = c^2

841 = c^2

29 = c

If you are using angle B as your theta (angle from which the relations are formed:

a) sin = O/H = 20/29

b) cos = A/H = 21/29

c) tan = O/A = 20/21

Answer:

a) 0.4567

b) 6 hours

Step-by-step explanation:

We are given the following information the question:

The battery life follows a normal distribution with

$\mu = 9.75\\\sigma = 2.3$

Formula:

$z = \displaystyle\frac{x-\mu}{\sigma}$

a) We have to find probability such that battery life exceeds 10 hours, that is,

P(X>10)

$P(z > \displaystyle\frac{10 - 9.75}{2.3}) = P(z>0.1086)\\\\= 1 - P(z \leq 0.1086)\\= 1- 0.5433\\=0.4567$

b) We have to find battery life such that

$P(X \leq x) = 0.05\\\\P(z \leq \displaystyle\frac{x-9.75}{2.3}) = 0.05\\\\\displaystyle\frac{x-9.75}{2.3} = -1.64 \\\\x = (-1.64)(2.3) + 9.75\\x = 5.978$

Here, we calculated the value of z from the normal distribution table.

So, after approximately 6 hours one should plan to recharge the phone.
