the expression is simplified to give - 39

<h3>How to simply the expression</h3>

Given the expression;

= 24- 4 to the power of 2 x 3+15

= 24 - (4^2 × 3 ) + 15

First, expand the bracket

= 24 - ( 16 × 3) + 15

Find the product of the bracket

= 24 - 48 + 15

From our knowledge of BODMAS, we add before we subtract

Now, let's add first

= 24 - 63

The, subtract

= - 39

The expression is simplified to - 39

Thus, the expression is simplified to give - 39

A father lifts a toddler 1.5 m up in the air. The child gains 187.5 J of energy in her gravitational potential energy store as a

professor190 [17]

The mass of the toddler is 12.5 kg

Step-by-step explanation:

Gravitational potential energy (GPE) =

mass (m) × height (h) × gravitational field strength (g)

1. Gravitational potential energy is measured in (J)

2. Mass is measured in (kg)

3. Height is measured in (m)

4. Gravitational field strength (g) is measured in (N/kg)

∵ A father lifts a toddler 1.5 m up in the air

∴ h = 1.5 m

∵ The child gains 187.5 J of energy in her gravitational potential

energy store as a result

∴ GPE = 187.5 j

- Assume that the gravitational field strength is 10 N/kg

∴ g = 10 N/kg

Substitute the values of GPE , h and g in the rule above to find m

∵ GPE = m h g

∴ 187.5 = m × 1.5 × 10

∴ 187.5 = 15 m

- Divide both sides by 15

∴ m = 12.5 kg

The mass of the toddler is 12.5 kg

Pepsi [2]

Greg is driving a remote control car at a constant speed. He starts the timer when the car is 5ft away after 2 seconds the car is 35ft away

Let x be the seconds and y be the feet the car is away

In 0 seconds the car is 5ft away. (0, 5)

In 2 second the car is 35 ft away (2, 35)

Question says constant speed

so we find linear equation y=mx+b

use the points (0,5) and (2,35)

slope $m = \frac{y_2-y_1}{x_2-x_1} = \frac{35-5}{2-0}= 15$

y intercept is 5

so equation becomes y = 15x + 5

to find the distance the car has traveled after 10 secs

We plug in 10 for x and find out y

y = 15(10) + 5= 150+5= 155

the distance the car has traveled after 10 secs is 155 feet
