Answer:

Candy necklaces: 5.98 ( 6 dollars rounded up)

Jane bought 3 pounds of gummy bears

Step-by-step explanation:

I got 5 dollars for the first one because the candy necklaces are 4 dollars a pound so if he got 1.5 ( 1 pound and a half) that means the 1 pound( 4 dollars) plus .5 pound(2 dollars) equals 6

I figured out Jane bought 3 pounds by simply dividing 9.75 by 3.25

(I CANT ANSWER THE LAST TWO BECAUSE I NEED TO SEE THE FULL PAGE)

so if you ask another question and have the whole page in it (make sure its not blurry) then i can help you

Which of these choices show a pair of equivalent expressions? A.7^5/7 and (√ 7)^5 B.6^7/2 and (√ 6)^7 C.(4√ 81)^7 and 81^7/4 D.5
OverLord2011 [107]
We will use the following law of indices (or 'index law') to check each pair of expression

x^{ \frac{m}{n}} = ( \sqrt[n]{x} )^{m}

With fractional power, the denominator is the root and the numerator is the power of the term. When the denominator is 2, we usually only write the normal square symbol (√). Denominator other than 2, we usually write the value of the root, for example, the cubic root ∛

Option A - Incorrect
7^{ \frac{5}{7}} should equal to ( \sqrt[7]{7} )^{5}

Option B - Correct
6^{ \frac{7}{2} } does equal to ( \sqrt{6}) ^{7}

Option C - Incorrect
4( \sqrt{81} )^{7} should equal to (4)( 81^{ \frac{7}{2} } )

Option D - Incorrect
5^{ \frac{2}{3} } should equal to ( \sqrt[3]{5} )^{2}

-4(x+3)=8 show work please
Nadusha1986 [10]

Answer:

x = -5

Step-by-step explanation:

-4(x+3)=8

(-4)(x)+(-4)(3)=8 (distribute)

-4x - 12 = 8

-4x - 12 + 12 = 8 + 12

-4x = 20

-4x/-4 = 20/-4 =

x = -5

Why is the answer to this integral's denominator have 1+pi^2
ss7ja [257]

It comes from integrating by parts twice. Let

I = \displaystyle \int e^n \sin(\pi n) \, dn

Recall the IBP formula,

\displaystyle \int u \, dv = uv - \int v \, du

Let

u = \sin(\pi n) \implies du = \pi \cos(\pi n) \, dn

dv = e^n \, dn \implies v = e^n

Then

\displaystyle I = e^n \sin(\pi n) - \pi \int e^n \cos(\pi n) \, dn

Apply IBP once more, with

u = \cos(\pi n) \implies du = -\pi \sin(\pi n) \, dn

dv = e^n \, dn \implies v = e^n

Notice that the ∫ v du term contains the original integral, so that

\displaystyle I = e^n \sin(\pi n) - \pi \left(e^n \cos(\pi n) + \pi \int e^n \sin(\pi n) \, dn\right)

\displaystyle I = \left(\sin(\pi n) - \pi \cos(\pi n)\right) e^n - \pi^2 I

\displaystyle (1 + \pi^2) I = \left(\sin(\pi n) - \pi \cos(\pi n)\right) e^n

\implies \displaystyle I = \frac{\left(\sin(\pi n) - \pi \cos(\pi n)\right) e^n}{1+\pi^2} + C

Y+5=-(x+5) in standard form
swat32

1. y+5=-x-5

2. y=-x-5-5

3.y=-x-10

4. y=x-10

_______________________

1. distribute negative sign

2. move the constant to the right and change the sign

3. -5-5 equals -10, bring everything down

4. change the sign of the x to positive, the equation is in standard form
