Answer:

4th Option is correct that is constant term is given expression is 17.

Step-by-step explanation:

Given Algebraic Expression = $-2x^2+17-15x+7xy$

We need to find Constant term in the given algebraic expression.

We know that Constant term in the Expression are term which has only numbers not a variable.

So, In given expression $-2x^2\:,\:-15x\:and\:7xy$ are not constant terms as all terms has variables.

Only 17 is constant term.

Therefore, 4th Option is correct that is constant term is given expression is 17.

Step-by-step explanation:

1 day = 0.75 hours of practicing in a day.

365.25 = x

1/365.25 = 0.75/x Cross multiply

x = 0.75 * 365.25 Combine

x = 273.94 hours

Two sides of a triangle measure 27 inches and 32 inches. Which could represent the length of the third side?

charle [14.2K]

Answer:

Step-by-step explanation:

The third side could have dimension x

32 - 27 < x < 32 + 27

5 < x < 59

There are a few special triangles

Equilateral triangle could have legs

27, 32, 27

32, 27, 32

A right triangle could have the third side

√(27² + 32²) = √1753 which is about 41.87

√(32² - 27²) = √295 which is about 17.18

Notice all these fit within the original limits specified.

kirill115 [55]

Answer:

12 feet per second.

Step-by-step explanation:

Please consider the complete question.

Ian tosses a bone up in the air for his dog, Spot. The height, h, in feet, that Spot is above the ground at the time t seconds after she jumps for the bone can be represented $h(t)=-16t^2+20t$ .

What is Spot's average rate of ascent, in feet per second, from the time she jumps into the air to the time she catches the bone at t=1/2?

We will use average rate of change formula to solve our given problem.

$\text{Average rate of change}=\frac{f(b)-f(a)}{b-a}$

$\text{Average rate of change}=\frac{h(\frac{1}{2})-h(0)}{\frac{1}{2}-0}$

$\text{Average rate of change}=\frac{-16\cdot(\frac{1}{2})^2+20\cdot \frac{1}{2}-(-16\cdot(0)^2+20\cdot (0))}{\frac{1}{2}-0}$

$\text{Average rate of change}=\frac{-16\cdot\frac{1}{4}+10-(0)}{\frac{1}{2}}$

$\text{Average rate of change}=\frac{-4+10}{\frac{1}{2}}$

$\text{Average rate of change}=\frac{6}{\frac{1}{2}}$

$\text{Average rate of change}=\frac{2\cdot 6}{1}$

$\text{Average rate of change}=12$

Therefore, Spot's average rate of ascent is 12 feet per second.

You deposit $3000 into a bank account that pays 1.25% annual interest, compounded semi-annually. What is the final balance after

mojhsa [17]

Answer:

$3,153.32

Step-by-step explanation:

Given that

The deposited amount is $3,000

The annual interest rate is 1.25%

So, the semi-annual interest rate is 1.25% ÷2 = 0.625%

And, the time period = 4 × 2 = 8

We need to find out the final balance

So,

As we know that

Future value = Present value × (1 + rate of interest)^number of years

= $3,000 × (1 + 0.625%)^8

= $3,153.32
