The equation is 329-34 and then you check if you sibtract right by adding 34 by the nimber you got when you subtract if it gives you 329 you are right

329 - 34! This one is really easy. You always subtract the number you have, here being 34, by the number you need, here being 329.

An arc with a measure of 190° has an arc length of 40<img src="https://tex.z-dn.net/?f=%5Cpi" id="TexFormula1" title="\pi" alt="

Anna007 [38]

Answer:

37.9 cm

Step-by-step explanation:

Arc length is:

s = 2πr (θ/360°)

where r is the radius and θ is the arc angle.

40π cm = 2πr (190°/360°)

20 cm = r (190°/360°)

r = 37.9 cm

The first steps in writing f(x) = 4x2 + 48x + 10 in vertex form are shown. f(x) = 4(x2 + 12x) + 10 (twelve-halves) squared = 36

brilliants [131]

Answer:

$f(x)=4(x+6)^2-134$

Step-by-step explanation:

We are required to write the function $f(x) = 4x^2 + 48x + 10$ in vertex form.

First, bring the constant to the left-hand side.

$f(x) -10= 4x^2 + 48x$

Factorize the right hand side.

$f(x) -10= 4(x^2 + 12x)$

Take note of the factored term(4) and write it in the form below.

$f(x) -10+4\Box= 4(x^2 + 12x+\Box)$

$\Box = (\frac{\text{Coefficient of x}}{2} )^2\\\\\text{Coefficient of x}=12\\\\\Box = (\frac{12}{2} )^2 =6^2=36$

Substitute 36 for the boxes.

$f(x) -10+4\boxed{36}= 4(x^2 + 12x+\boxed{36})$

$f(x) -10+144= 4(x^2 + 12x+6^2)$

$f(x) +134= 4(x+6)^2\\f(x)=4(x+6)^2-134$

The function written in vertex form is $f(x)=4(x+6)^2-134$

What percent of 200 is 90

Feliz [49]

In math
"of" means x
"is" means =

x% of 200 is 90
x * 200 = 90
x = 90/200 = .45

Multiply by 100 to convert to percent

.45 = 45%

90 is 45% of 200
