Equation : a^2 + ( 2b - c) x d, solve for a=2, b=5, c=8, and d=4!! help pls and work

1 answer:

4 0

The first step for solving this expression is to insert the numbers for a, b, c, and d. This will change the expression to the following:
2² + (2(5) - 8) x 4
Now we need to evaluate the power of the first number.
4 + (2(5) - 8) x 4
Next you'll multiply the first two numbers in the parenthesis together.
4 + (10 - 8) x 4
Subtract the numbers in the parenthesis
4 + 2 x 4
Now multiply the two numbers together (remember PEMDAS)
4 + 8
Finally,, add the two numbers together to get your final answer.
12
This means that the correct answer to your question is going to be 12.
Let me know if you have any further questions

Answer: 7. g = -50, 8. f= 340/6 9. 3 10 .125

Step-by-step explanation:#7 g(3): 4(3)^2 +6 =12^2 +6 = 1444=6= 150. We divide 150 by 3 giving us -50. #8We start by putting f(6): -3(6)^2 -4(6) +8. We use PEMDAS. -18^2 -24 +8 = _324-24+8 F= 340/6 #9 g(15) = Square root of 15-6=9 and the square root of 9 is 3, therefore, the answer is 3. #10 h (x) = 2^x we plug -3 to 2^-3. It is a negative number and it gives us .125 or 12.5

The circle with center O has a minor arc BSA with a length of

tangare [24]

Answer:

D. $\frac{27\pi}{2}$ inches.

Step-by-step explanation:

We have been given that the circle with center O has a minor arc BSA with a length of $3\pi^{2}$ inches. The central angle is 40°.

To find the circumference of circle we will use formula:

$\frac{\text{Central angle}}{2\pi}=\frac{\text{Arc length}}{2\pi r}$ , where $2\pi$ = measure of 360 degrees in radians and $2\pi r$ = circumference of circle.

Let us convert measure of central angle into radians.

$40^{o}=\frac{40*\pi}{180} =\frac{2\pi}{9}$

Upon substituting our given value in the formula we will get,

$\frac{\frac{2\pi}{9}}{2\pi}=\frac{\frac{3\pi}{2}}{2\pi r}$

$\frac{2\pi}{18\pi}=\frac{3\pi}{4\pi r}$

$\frac{1}{9}=\frac{3}{4r}$

Cross multiplying we will get,

$4r=27$

$r=\frac{27}{4}$

Hence, the radius of our circle is 27/4 inches.

Since the circumference of circle is $2\pi r$ . Upon substituting $r=\frac{27}{4}$ we will get,

$2\pi r=2\pi* \frac{27}{4}=\frac{27\pi}{2}$

Therefore, circumference of our given circle will be $\frac{27\pi}{2}$ inches and option D is the correct choice.

Enter the number that goes beneath the radical symbol

Lunna [17]

Answer:

185

Step-by-step explanation:

It seems like you're using the Pythagorean theorem, which would mean that b is equal to $\sqrt{11^2 -8^2}$ , which is equal to $\sqrt{185}$ . The number beneath the radical symbol is <u><em>185</em></u>.
