Answer:

see explanation

Step-by-step explanation:

Using the rule of exponents

$(a^m)^{n}$ ⇔ $a^{mn}$

That is each exponent of the terms inside the parenthesis is multiplied by the exponent outside the parenthesis

$(xy^{4}) ^{6}$

= $x^{1(6)}$ $y^{4(6)}$

= $x^{6}$ $y^{24}$

Use the net to find the lateral area of the cylinder.

ioda

The lateral area is the area around, the bases are the circles so the lateral area is the area of the rectangle

we just need the legnth of the rectangle which is the circumfernece of the circle

C=pid
d=12
C=12pi

area=lw
aera=12pi*15
area=180pi yd^2

A new weight-watching company, Weight Reducers International, advertises that those who join will lose an average of 10 pounds a

Ksenya-84 [330]

Answer:

The calculated value Z = 2.53 >1.96 at 0.05 level of significance

Null hypothesis H₀ is rejected

we accepted alternative hypothesis

we conclude that those joining Weight Reducers will lose greater than 10 pounds

Step-by-step explanation:

Step(i):-

Given the random sample size 'n' =50

Given data a new weight-watching company, Weight Reducers International, advertises that those who join will lose an average of 10 pounds after the first two weeks. The standard deviation is 2.8 pounds.

The mean of the Population 'μ' = 10pounds

The standard deviation of the Population 'σ' = 2.8 pounds

Given mean of the sample 'x⁻' = 9

Level of significance ∝ = 0.05

Step(ii):-

Null hypothesis :H₀: μ<10

Alternative hypothesis: H₁: μ>10

The test statistic

$z= \frac{x^{-} - mean}{\frac{S.D}{\sqrt{n} } }$

$z= \frac{9 - 10}{\frac{2.8}{\sqrt{50} } } = \frac{-1}{0.395} = 2.53$

The calculated value Z = 2.53

The tabulated value Z = 1.96 at 0.05 level of significance

Step(iii):-

The calculated value Z = 2.53 >1.96 at 0.05 level of significance

Null hypothesis H₀ is rejected

we accepted alternative hypothesis

Conclusion:-

we conclude that those joining Weight Reducers will lose greater than 10 pounds

The reflecting dish of a parabolic microphone has a cross-section in the shape of a parabola. The microphone itself is placed on

pochemuha

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
If we set the vertex at (0,0) then the curve goes through (30,30)

y = 1/30 x^2 
x^2 = 30y 

Since the parabola x^2 = 4py has its focus at y=p, 4p=30 and the mic should be 15/2 inches up from the vertex.

Write an equation of the line that passes through (−2, −1) and is perpendicular to 2y =3x−5.

marusya05 [52]

Answer:

y = 2/3x - 1

Step-by-step explanation:

Find the slope:

2y = 3x - 5

2/2y = 3/2x - 5/2

y = 3/2x - 5/2

Slope is 3/2

In order for a line to be perpendicular the slope in the equation should be flipped. 3/2 becomes 2/3.

Perpendicular equation:

y = 2/3x + b

b is going to be equal to the y intercept of the point they gave us, so -1.

Answer: y = 2/3x - 1
