Hey! i’m pretty sure the answer is 10

The answer would be 10 because the full side is 20 and it’s only asking for half the side so it would be 10

vodka [1.7K]

Answer:

$\Large \boxed{\mathrm{A) \ 7}}$

Step-by-step explanation:

The triangle is a right triangle.

We can use trigonometric functions to solve the problem.

tan(θ) = opp/adj

tan(35) = x/10

Multiply both sides by 10.

10 tan(35) = x

x = 7.00207538...

under a dilation, the point (2,6) is moved to (6,18) what is the scale factor of the dilation? enter your answer in the box

Anestetic [448]

Step-by-step explanation:

The equation of line passing through the two points is $\frac{y-y_{1} }{x-x_{1} }=\frac{y_{2} -y_{1}}{x_{2} -x_{1}}$

When substituted,the equation becomes $\frac{y-6}{x-2}=\frac{18-6}{6-2}$

which when simplified is $y=3\times x$

The line clearly passes through origin.

The distance between two points is $\sqrt{(y_{1}-y_{2} )^{2}+(x_{1}- x_{2} )^{2}}$

Distance between origin and $(2,6)$ is $\sqrt{40}$ .

Distance between origin and $(6,18)$ is $\sqrt{360}$

Scale factor is $\frac{distance\text{ }of\text{ }p_{2}\text{ from origin}}{distance \text{ } of \text{ } p_{1}\text{ from origin}}$

So,scale factor is $\frac{\sqrt{360} }{\sqrt{40} }$

which when simplified becomes 3.

Whats the coefficient of 1/2x^2+x+7

dsp73

Answer:

Step-by-step explanation:

The coefficient of a variable is the number that the variable is being multiplied for. In this example. We can see that x² is being multiplied by 1/2, therefore <u>1/2 is one of the coefficients</u>.

In the case of x, it doesn't have a number before it, it means that it's being multiplied by 1. Hence, our <u>second coefficient is 1</u>.
