What multiplies to 40 but adds to 22

Answers

Answer 1

Answer: 20 and 2
2*20=40
2+20=22

3/4

Step-by-step explanation:

-2 1/4÷(-3 1/3)

First convert the mixed number to an improper fraction

That's

$- 2 (1)/(4) = - (9)/(4)$

And

$- 3 (1)/(3) = - (9)/(3)$

So we have

$- (9)/(4) / - (9)/(3)$

Simplify

Change the division sign to multiplication sign and reverse the second number

That's

$- (9)/(4) * - (3)/(9)$

Simplify

We have the final answer as

$(3)/(4)$

Hope this helps you

Answer:

27/40

Step-by-step explanation:

-2 1/4÷(-3 1/3)

first convert into improper fraction

-9/4 ÷ -10/3

Change the division sign by multiplying by the inverse of -10/3

the inverse of -10/3 = -3/10

-9/4 × -3/10 = (-9×-3)/(4×10)

= 27/40

27/40 is a proper fraction

Therefore, the simplified form of -2 1/4÷(-3 1/3) = 27/40

Which value of theta is not in the domain of validity for csc theta =1/sin theta

Answers

Answer with explanation:

The given expression is:

$\csc \Theta^(\circ) =(1)/(\sin \Theta^(\circ))$

Domain of Cosec theta,will be all values in Radian or degree except at the point where,

→sine(theta)≠ 0.

If theta is in either Degrees or in Radian, then

$\Theta\neq k \pi ,\text{Where k, is any Integer}$

The value of theta which is not in the domain for the validity of

$\csc \Theta^(\circ) =(1)/(\sin \Theta^(\circ))$

is, →→Theta(Ф)≠ k π, for any integer ,k.

Verify each identity give the domain of validity for each identity. It is very used to prove these identities for any value of theta in the domain. So I just specify the domain and leave verification for you to do t with standard values or on calculator. Because verification is an endless process. Proof is not. As proof seems to be simple I will do that which will amount to verification as well

The answer to the question is B.

32) Identify the turning point of the function f(x)= x^2-2x+8 by writing its equation in vertex form. Show your work.

Answers

(1,7)

Working;
Start by finding the derivative of the function f(x);
$f^(') (x)$ =2x-2
Turning points occur when the derivative function=0;
Thus
2x-2=0
x=1
when x=1 then
f(1)= $1^(2) -2(1)+8$
=7
Turning point then is (1,7)
