Answer:

Part 1) $x=44.80\ units$

Part 2) $y=56.85\ units$

Step-by-step explanation:

Part 1) Find the value of x

we know that

In the right triangle of the figure

The tangent of angle of 52 degrees is equal to divide the opposite side to the angle of 52 degrees (x units) by the adjacent side to the angle of 52 degrees (35 units)

$tan(52\°)=x/35$

Solve for x

$x=(35)tan(52\°)$

$x=44.80\ units$

Part 2) Find the value of y

we know that

In the right triangle of the figure

The cosine of angle of 52 degrees is equal to divide the adjacent side to the angle of 52 degrees (35 units) by the hypotenuse (y units)

$cos(52\°)=35/y$

Solve for y

$y=35/cos(52\°)$

$y=56.85\ units$

Keenan wants to make a paperweight at pottery class. He designs a pyramid-like model with a base area of 808080 square centimete

slamgirl [31]

Answer:

<h2>The weight of Keenan's paperweight is 3.33 N.</h2>

Step-by-step explanation:

Givens

The base area is 80 square centimeters.
The height of the pyramid is 7.5 centimeters.
The density of the pyramid is 1.7 grams per cubic centimeters.

First, we find the volume of the figure.

$V=\frac{1}{3} (B \times h)$

Where $B=80cm^{2}$ and $h=7.5 cm$ .

Replacing values, we have

$V=\frac{1}{3}(80)(7.5)=200cm^{3}$

The density is defined as

$\rho=\frac{m}{V}$

Where we need to find the mass $m$ , we already know that $\rho=1.7 \ gr/cm^{3}$ and $V=200cm^{3}$ . Replacing these values, and solving for $m$

$1.7=\frac{m}{200}\\ m=1.7(200)=340 \ gr$

Then, we use the weight definition, which is

$W=mg$

Where $m=340 \ gr=0.34 \ kg$ and $g=9.81 m/sec^{2}$ . Replacing these values, we have

$W=0.34(9.81)\\W=3.33 N$

Therefore, the weight of Keenan's paperweight is 3.33 N.

Given the following function, find <br> h(3).<br> h(t) = t2 − t + 7

g100num [7]

Answer:

Step-by-step explanation:

h(t) = t² - t + 7

h(3) = 3² - 3 + 7 = 9 - 3 + 7 = <em>13</em>

Sven determined that the x-coordinate is approximately 3.6 because the point is closer to 4 than 3 and seems to be a little more

mezya [45]

The y-coordinate is between -1 and -2. It is close to halfway between -1 and -2, but it is a little less than halfway.

Answer: Choice B. $y \approx -1.4$
