Answer:

slope is 2/3

Step-by-step explanation:

To solve for slope: y2-y1 / x2- x1.

Two points can be (0,50) and (30,70) since they intercept.

70-50 / 30- 0 = 20/30 = 2/3.

The slope is also going 20 units up and 30 units across which gives you 2/3.

A hexagonal prism has a base with an area of 15 square inches and the volume is 105 cubic inches.

Lina20 [59]

Answer:

The height is 7 inches

Step-by-step explanation:

Given

$Base\ Area = 15in^2$

$Volume = 105in^3$

Required

Determine the height [missing from the question]

The volume of a hexagonal prism is:

$Volume = Base\ Area * Height$

Make Height the subject

$Height = \frac{Volume}{Base\ Area}$

$Height = \frac{105in^3}{15in^2}$

$Height = \frac{105in}{15}$

$Height = 7in$

It's a question from real and complex numbers which I can't solve. so someone PLZ HeLp

Semmy [17]

Answer:

$\frac{1}{5}$

Step-by-step explanation:

Using the rules of exponents

$a^{m}$ × $a^{n}$ = $a^{(m+n)}$ , $\frac{a^{m} }{a^{n} }$ = $a^{(m-n)}$ , $(a^m)^{n}$ = $a^{mn}$

Simplifying the product of the first 2 terms

$\frac{a^{p^2+pq} }{a^{pq+q^2} }$ × $\frac{a^{q^2+qr} }{a^{qr+r^2} }$

= $a^{p^2-q^2}$ × $a^{q^2-r^2}$

= $a^{p^2-r^2}$

Simplifying the third term

5( $(a^p+r)^{p-r}$

= 5 $a^{(p+r)(p-r)}$ = 5 $a^{(p^2-r^2)}$

Performing the division, that is

$\frac{a^{(p^2-r^2)} }{5a^{(p^2-r^2)} }$ ← cancel $a^{(p^2-r^2)}$ on numerator/ denominator leaves

= $\frac{1}{5}$
