a^2 + b^2 = c^2

24^2 + b^2 = 74^2

576 + b^2 = 5,476

-576 -576

b^2 =4,900

(square root)

b =70

Solve 9x + 3 = -33 . PLEASE HELP ME IT WILL MAKE MY DAY

ValentinkaMS [17]

$: \implies \sf 9x + 3 = - 33$

$: \implies \sf 9x = - 33 - 3$

$: \implies \sf 9x = - 36$

$: \implies \sf x = \dfrac{ - 36}{9} = - 4$

$\therefore \sf x = -4$

Is the sqrt of 1 - sin^2 theta = cos theta true? If so, in which quadrants does angle theta terminate?

Genrish500 [490]

Answer:

Answer: The answer is option B.

Step-by-step explanation:

Here,

We have,

${ \sin }^{2} theta \: + {cos}^{2}theta = 1$

${cos}^{2} \: theta = 1 - {sin}^{2} \: theta$

$cos \: theta = \sqrt{1 - { \sin }^{2}theta }$

So, it's true; and it lies in quadrant 1 and 4.

The reason according to the "CAST" rule cos theta is in 1st and 3rd quadrant cos theta is positive.

Ribbon is only sold by the spool. A spool contains 25 yards of ribbon. Shannon needs 58 yards of ribbon to wrap all the presents

ella [17]

Answer:

$\boxed{\text{3 spools}}$

Step-by-step explanation:

$\text{1 spool =25 yd}\\\text{Spools needed } = \text{58 yd} \times \dfrac{\text{1 spool}}{\text{25 yd}} = \text{2.32 spools}\\\\\text{However, Shannon can't buy part of a spool. She must $\textbf{round up}$ to the next integer.}\\\text{Shannon must buy $\boxed{\textbf{3 spools}}$ of ribbon}$

G(x) = x^2– 5x f(x) = 2x +1<br> Find (g - f)(x)

Brrunno [24]

Answer:

x^2 - 7x - 1

Step-by-step explanation:

g(x) = x^2– 5x

f(x) = 2x +1

(g - f)(x)

expand to get

gx - fx

Slot in the values

(x^2– 5x) - (2x +1)

expand

x^2 - 5x - 2x - 1

x^2 - 7x - 1

Evaluate [20x ÷ 5 · (-x)] + 3

Anna35 [415]

Order of operations, the order in which to do them
pemdas
parenthasees
exponents
multiplication or division (whichever comes first)
addition or subtraction (whichever comes first)
so

inside parenthaees first
20x/5=4x

now we has
[4x*(-x)]+3
multiply
4x*-x=-4x²

now we has
[-4x²]+3
-4x²+3 is the eavlauted form
