Answer:

I believe it would be C, 8 squared.

Step-by-step explanation:

8 squared means to multiply 8 twice. Not by two, 8 times 8. If you do that, you will get 64. This means that 8 squared is equivalent to 64'1

Write the equation of the line that passes through each pair of point (1,2) (-1,-3)

kobusy [5.1K]

Answer: y = 3

Step-by-step explanation:

So, we must find an equation of a line that passes through these two points such that we find the slope first as,

m = (3-3) / (2-(-1)) = 0 / 3 = 0. Then we bring up the point-slope form of an equation to find the line such that

y - y1 = m(x - x1). Next,

y - 3 = 0(x - (-1))

y - 3 = 0..............Then add 3 such that the equation of a line is

A photo that is 4 in. wide and 6 in. high is enlarged to a

riadik2000 [5.3K]

Answer:

The ratio of the width of the photo to the width of the poster is 1:9 or 1/9

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Photo = 4 in. wide and 6 in. high

Poster = 3 ft wide and 4 ft high

2. What is the ratio of the width of the photo to the width of the poster?

Let's recall that 1 foot = 12 inches

Let's convert the width of the poster to inches, this way:

3 feet = 3 * 12 inches

3 feet = 36 inches

The width of the poster is 36 inches

Now, we calculate the radio, as follows:

Ratio = Width of the photo in inches/Width of the poster in inches

Ratio = 4/36 = 1/9 (Simplifying)

The ratio of the width of the photo to the width of the poster is 1:9 or 1/9

Indicate whether the following congruence statement is true or false. 50 points

Nostrana [21]

Step-by-step explanation:

Since line NL is not necessarily congruent to MQ (labelled with different congruent marks), triangle NLM is not congruent to triangle MQP.

Instead, triangles NLM and QPM are congruent.

Given the quadrant of theta in standard position and a trigonometric function value of theta , find the exact value for the indi

SVETLANKA909090 [29]

Answer:

$\sqrt{15}$

Step-by-step explanation:

$\cos(\theta)=\frac{1}{4}$ is given.

My attempt will to be to use the Pythagorean Identity:

$\cos^2(\theta)+\sin^2(\theta)=1$

$(\frac{1}{4})^2+\sin^2(\theta)=1$

$\frac{1}{16}+\sin^2(\theta)=1$

Subtract 1/16 on both sides:

$\sin^2(\theta)=\frac{15}{16}$

We have the following quotient identity:

$\frac{\sin^2(\theta)}{\cos^2(\theta)}=\tan^2(\theta)$

$\frac{\sin^2(\theta)}{\cos^2(\theta)}=\frac{\frac{15}{16}}{\frac{1}{16}}$

Multiply the numerator and denominator by 16. This is multiplying the fraction by 1 so this doesn't change the value of the fraction.

$\tan^2(\theta)=\frac{15}{1}$

$\tan^2(\theta)=15$

Square root both sides:

$\tan(\theta)=\pm \sqrt{15}$

Since we are in the first quadrant then all 6 trigonometric functions are positive there so the answer is $\sqrt{15}$ .
