You made Marcellus 3 times as tall as Dan but you dragged Marcellus’s mouth to be 5.46 times as wide as Dan’s mouth. A proportio

nal giant would have the same multiple for both.
If Dan's mouth is 4 cm wide, how many centimeters wide should Marcellus's mouth be?

Answer:

1. x=4

2. x=6

Step-by-step explanation:

I've attached the graphs here:

Clearly, the solution for first one is(Reminder: the solution is the x-intercepts, when y is zero):

x=4

And the second is:

x=6

Hope this helps!

Function g can be thought of as a translation (shifted) version of f(x)=x^2
Natasha_Volkova [10]

Answer:

Step-by-step explanation:

f(x)=x^2  represents a parabola with vertex at (0, 0), that opens up.

If we translate this graph h units to the right, then g(x) will be:

g(x) = (x - h)^2.

If we translate the graph of  f(x)=x^2 k units up, then g(x) will be:

f(x)=x^2 + k

Next time, please indicate whether you are shifting the original graph to the right or to the left, and/or up or down.

In a study of cell phone usage and brain hemispheric​ dominance, an Internet survey was​ e-mailed to 6977subjects randomly selec
kirza4 [7]

Answer:

Given :An Internet survey was​ e-mailed to 6977 subjects randomly selected from an online group involved with ears. There were 1337 surveys returned.

To Find : Use a 0.01 significance level to test the claim that the return rate is less than​ 20%.

Solution:

n = 6977

x = 1337

We will use one sample proportion test

\widehat{p}=\frac{x}{n}

\widehat{p}=\frac{1334}{6977}

\widehat{p}=0.1911

We are given that the claim is the return rate is less than​ 20%.

H_0:p=0.2\\H_a:p

Formula of test statistic = \frac{\widehat{p}-p}{\sqrt{\frac{p(1-p)}{n}}}

                                       = \frac{0.1911-0.2}{\sqrt{\frac{0.2(1-0.2)}{6977}}}

                                       = −1.858

Refer the z table

P(z<-1.85)=0.0332

Significance level = 0.01=α

Since p value > α

So, we accept the null hypothesis .

So,the claim that the return rate is less than​ 20% is false.

ANSWER:

We know that angle fromed by same arc are congruent. so

∠ACB ~ ∠ADB

∠CAD ~ ∠CBD

Therefore, ΔCAF ~ ΔDBF by AA similarity. So, By CPCT

arcAC = arcBD.
