6. Which expression is equivalent to -21 + 28x?

Rina8888 [55]

Solution,
-28x^2+35x
take the common,
-7x(4x-5)
The answer is -7x(4x-5)
Here,
If we solve,
-7x(4x-5)
Then, the answer would be:
= -7x*4x+7x*5
= -28x^2+35x
Hope it helps

The radius of a semicircle is 3 feet. What is the semicircle's area?<br>Use 3.14 for Pi

valentinak56 [21]

Answer:

14.13 ft²

Step-by-step explanation:

The area of a semicircle is

$= \frac{\pi \: {r}^{2} }{2}$

We were given the radius of the semicircle to be: r=3 feet.

We were also asked to use π as 3.14.

We substitute into the formula to get:

$= \frac{3.14 \times {3}^{2} }{2}$

This is the same as:

$= \frac{3.14 \times 9}{2}$

$= 3.14 \times 4.5$

$= 14 .13 {ft}^{2}$

The area of the semicircle is 14.13 ft²

The Pythagorean theorem tells you of the relation ...

x² + 6² = 10² . . . . . . . . . squares of sides total to the square of hypotenuse

x² = 100 -36 = 64 . . . . . subtract 6²

x = √64 = 8 . . . . . . . . . . square root

harina [27]

Answer:

0.8809 = 88.09% probability the ships will sail full.

Step-by-step explanation:

What is the probability the ships will sail full?

0.75 of 0.23(dollar appreciating)

0.92 of 1 - 0.23 = 0.77(dollar not appreciating). So

$p = 0.75*0.23 + 0.92*0.77 = 0.8809$

0.8809 = 88.09% probability the ships will sail full.

What is the domain of the function f(s)=7s +15? what is the range?

timama [110]

It's a linear function.

Domain of a linear function is the set of all real numbers.

If the slope of linear function is different than 0, then range is the set of all real numbers.

We have f(s) = 7s + 15. The slope = 7 ≠ 0. Therefore:

Answer: $Domain=\mathbb{R};\ Range=\mathbb{R}$
