Answer:

z=-3

Step-by-step explanation:

The given line has slope m=-7.

The line passes through (-1,-8) and (z,6).

We use the slope formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

We substitute $x_1=-1$ , $y_1=-8$ , $x_2=z$ , $y_2=6$ and $m=-7$ to get:

$-7=\frac{6--8}{z--1}$

$-7=\frac{6+8}{z+1}$

$-7=\frac{14}{z+1}$

$-7(z+1)=14$

Expand $-7z-7=14$

$-7z=14+7$

$-7z=21$

$z=-3$

Please help im so confused?

sattari [20]

Lets get started :)

The area formula of a cylinder is:
Area = $2(radius)^2+2 \pi (radius)(height)$

We are given:
The radius: 6 units
The height: 15 units

Apply the formula!

A = $2 \pi (6)^2+2(6)(15)$
= $72 \pi + 180 \pi$
= $252 \pi$ units²

Your answer will be option D

From triangle PQR is P = 90°, PQ = 15.5 dm and PR = 11,7 dm. Calculate QR in dm. Round to one decimal.

Irina18 [472]

Answer:

QR = 19.4

Step-by-step explanation:

Use Pythagoras because p = 90°

Qr is hypotenuse

; (15.5)² + (11.7)²

= 377.14

√377.14

= 19.42009

= 19.42

= 19.4

A car is driving at 70 kilometers per hour. How far, in meters, does it travel in 5 seconds?

notka56 [123]

Answer:

97.2 m

Step-by-step explanation:

$\frac{70 km}{1 h}$ = $\frac{70000 m}{3600 s}$ = 19.4 m/s

Distance = speed x time = 19.4 m/s x 5 s = 97.2 m
