Answer:

Step-by-step explanation:

Complementary angles add to 90 degrees

a+b = 90

64+b = 90

Subtract 64 from each side

64-64 +b = 90-64

b = 26

Estimate 10/12 − 3/8 using benchmark values. Your equation must show the estimate for each fraction and the final estimate for t

Maksim231197 [3]

Answer: $\frac{11}{24}$

Step-by-step explanation:

Give expression is,

$\frac{10}{12}-\frac{3}{8}$

Since L.C.M ( 12, 8 ) = 24

$=\frac{10\times 2}{12\times 2}-\frac{3\times 3}{8\times 3}$

$=\frac{20}{24}-\frac{9}{24}$

$=\frac{20-9}{24}$

$=\frac{11}{24}$

$\text{Hence, }\frac{10}{12}-\frac{3}{8}=\frac{11}{24}$

Which statement best describes how to determine whether f(x) = 9- 4x4 is an odd function?

vitfil [10]

Answer:

Option C.

Step-by-step explanation:

Note: In the given function the power of x should be 2 instead of 4, otherwise all options are incorrect.

Consider the given function is

$f(x)=9-4x^2$

If $f(-x)=f(x)$ , then $f(x)$ is an even function.

If $f(-x)=-f(x)$ , then $f(x)$ is an odd function.

Now, substitute x=-x in the given function.

$f(-x)=9-4(-x)^2$

$f(-x)=9-4(x)^2$

$f(-x)=f(x)$

So, the given function not an odd function. It means it is an even function.

To check whether the given function is odd, we have to determine whether $9-4(-x)^2$ is equivalent to $-(9-4(x)^2)$ .

Therefore, the correct option is C.

Which of the following expressions is equal to 2x2 + 18 ?

ehidna [41]

<h3>Answer: Choice C. (2x - 6i)(x + 3i)</h3>

Work Shown:

2x^2 + 18

2(x^2 + 9)

2(x - 3i)(x + 3i) .... see note below

(2x - 6i)(x + 3i)

Note: I used the rule that a^2 + b^2 = (a - bi)(a + bi). I recommend FOILing out the right hand side to confirm the equation is true. You'll use the idea that i^2 = -1.
