The kinetic energy K of a moving object varies jointly with its mass m and the square of the velocity v. If an object weighing 16 kilograms and moving with a velocity of 10 meters per second has a kinetic energy of 800 joules, find its kinetic energy when the velocity is 23 meters per second.

### Answers

**Answer:**

KE = 4232 J

**Step-by-step explanation:**

KE = 1/2 • mass • velocity^2

KE = 1/2 • 16kg • 23m/s ^2

KE = 8kg • 529 m/s

KE = 4232 J

**Answer:**

**Step-by-step explanation:**

If the quadratic equation has a root at [tex]\dfrac13[/tex] then when [tex]x=\dfrac13[/tex], [tex]y=0[/tex]

[tex]\implies x=\dfrac13[/tex]

[tex]\implies 3x=1[/tex]

[tex]\implies 3x-1=0[/tex]

If the quadratic equation has a root at [tex]\dfrac12[/tex] then when [tex]x=\dfrac12[/tex], [tex]y=0[/tex]

[tex]\implies x=\dfrac12[/tex]

[tex]\implies 2x=1[/tex]

[tex]\implies 2x-1=0[/tex]

Therefore, [tex]y=(3x-1)(2x-1)[/tex]

An angle measures 12° less than the measure of its complementary angle. What is the measure of each angle?

### Answers

Let ∠1 be x

Let ∠2 be x-12

ATQ,

[tex] \rm(x - 12 )+ x = 90 \degree[/tex]

[tex] \rm2x - 12 = 90 \degree[/tex]

[tex] \rm2x = 90 + 12[/tex]

[tex] \rm2x = 102[/tex]

[tex] \boxed{ \bf \: x = 51 \degree}[/tex]

So,

[tex] \sf \: ∠1 = x \\ \sf \: = 51 \degree[/tex]

[tex] \sf \: ∠2 = x - 12 \\ \sf = \: 51 - 12 \\ \sf∠2 = 39 \degree[/tex]

**Answer:**

one angle: 51° and other angle: 39°

**We can simply find:**

complementary angle is when two angles add up to 90°let one angle be xthen the another angle will be [ x - 12° ]

**Solve:**

x - 12 + x = 90

2x = 90 + 12

**x = 51°**

**one angle **→ **51°**

**other angle**: x - 12 → 51° - 12 → **39°**

A builder wants to increase the size of one of his square patios. The patio measures 16 feet on each side. The builder plans to increase each side of the patio to be 125% of its current measure.

How many square feet larger is the area of the new patio than the area of the current patio?

64 ft²

144 ft²

320 ft²

656 ft²

### Answers

The area of the **new patio** is **144 ft²** more than the area of **current patio.**

Calculating the area of a square

The length of the **current patio **= 16ft

The length of the **new patio =** 125% of 16ft

If 100% = 16ft

125% = xft

xft = 125% × 16/100

xft = 2000/100

x = 20ft

Area of the **current patio** = 16 × 16 = 256ft²

Area of squares in **new patio** = 20× 20 =400ft²

Therefore, The area of the **new patio** that is more than the area of **current patio** = 400 - 256 = **144ft²**

**Answer:**

The length is 312ft.

**Step-by-step explanation:**

Pythagorean Theorem!

a² + b² = c²

The hypotenuse is c, and the diagonal line is the hypotenuse.

we will replace b or a with 266, it doesn't matter, as long as the length is not whichever one I choose. I will replace b with 266. Now w know that the height is a.

a² + 266² = 410²

Use calculator

a² + 70756 = 168100

168100 - 70756 = 97344

√97344 = 312

The length is 312ft.

Example: 4 of what is 12%?

Written using the formula: X = 4 ÷ 12%

Solve for X: X = Y ÷ P%

Convert the percent to a decimal.

12% ÷ 100 = 0.12.

X = 4 ÷ 0.12.

Mrs. Galicia is watching the bacterial population grow at a rate of 30% per year. The bacteria population originally started at 20. After 8 years how many bacteria will be present?

A: 163

B: 208

C: 180

D: 36

### Answers

**Answer:**

A: 163

**Step-by-step explanation:**

Pit this in your calculator exactly like this 20(1.30)^8 Then hit x^y to the power of 8 and you get the answer 163.1461442 So round your answer to the nearest whole number, will be 163.

There are 163 **bacteria **after 8 years

The given parameters are:

Initial (a) = 20

Rate (r) = 30%

So, the exponential function is:

[tex]y = a(1 + r)^x[/tex]

This gives

[tex]y = 20(1 + 30\%)^x[/tex]

After 8 years, we have:

[tex]y = 20(1 + 30\%)^8[/tex]

Evaluate

[tex]y = 163[/tex]

Hence, there are 163 **bacteria **after 8 years
