Answer:

Step-by-step explanation:

Metal is stronger than plastic, but it is also much heavier.

The key idea in this paragraph is to highlight how to transport the required materials while reducing the weight as much as possible so orbital velocity can be achieved while breaking through the resistance of the atmosphere.

This statement is the key one because it gives engineers the problem they need to find the answer to make the space exploration a reality.

In the group of hundred students68 likes football 60 likes volleyball how many likes only football

diamong [38]

Answer:

18 students.

Step-by-step explanation:

Total amount is 100

Take 68 and add to 60 to get 128.

Subtract from both numbers until you get to 50.

68 needs 18 subtracted to get to 50.

60 needs 10 to get to 50.

18 plus 10 is 28, which is the excess.

Here, 18 people like only football.

In ∆XYZ, m∠X = 152, y = 15, and z = 19. Find side x and the measure of angle Y to the nearest tenth

solong [7]

The measure of the side $x$ is approximately 33 and the measure of angle $Y$ is approximately 12.321°.

<h3>How to find a missing angle in a triangle by law of sine and law of cosine</h3>

In this problem we must apply the law of cosine and the law of sine to determine the angle Y:

<h3>Law of cosine</h3>

$x = \sqrt{y^{2}+z^{2}-2\cdot y\cdot z\cdot \cos X}$

$x = \sqrt{15^{2}+19^{2}-2\cdot (15)\cdot (19)\cdot \cos 152^{\circ}}$

$x \approx 33$

$\frac{\sin Y}{y} = \frac{\sin X}{x}$

$Y = \sin^{-1}\left(\frac{y}{x}\cdot \sin X \right)$

$Y = \sin^{-1}\left(\frac{15}{33}\cdot \sin 152^{\circ} \right)$

$Y \approx 12.321^{\circ}$

The measure of the side $x$ is approximately 33 and the measure of angle $Y$ is approximately 12.321°. $\blacksquare$

denis-greek [22]

Answer:

Slope- 5 y-int- (0,0)

Step-by-step explanation:

y=mx+b, where m=slope and b=y-int. m=5, and we don't see a b, so it must be 0.
