Answer:

$MP= (5,4)$

Step-by-step explanation:

$MP= (\frac{x_1+x_2}{2} )(\frac{y_1+y_2}{2} )$

$MP= (\frac{2+8}{2} )(\frac{8+0}{2} )$ 2+8=10 8+0=8

$MP= (\frac{10}{2} )(\frac{8}{2})$ 10/2=5 8/2=4

$MP= (5,4)$

Answer:

$131.20

Step-by-step explanation:

$160 is the full price, so it is 100% of the full price.

With a discount of 18%, you pay 100% - 18% = 82% of the full price.

Given that x = -2 - 3i and y = 4 + 2i , Match The Expressions.

shtirl [24]

Answer:

$3y-2x=16+12i$

$-3x \cdot y=6+48i$

$x \cdot 2y=-4-32i$

$x-y=-6-5i$

Step-by-step explanation:

Given:

$x=-2-3i$

$y=4+2i$

---

1st problem:

$3y-2x$

$3(4+2i)-2(-2-3i)$

Distribute:

$12+6i+4+6i$

Combine like terms:

$16+12i$

---

2nd problem:

$-3x \cdot y$

$-3(-2-3i) cdot (4+2i)$

$-3(-2-3i)(4+2i)$

Distribute -3 to first factor:

$(6+9i)(4+2i)$

Use foil to simplify:

$24+12i+36i+18i^2$

Replace $i^2$ with -1:

$24+48i-18$

Combine like terms:

$6+48i$

---

3rd problem:

$x \cdot 2y$

$(-2-3i) \cdot 2(4+2i)$

Distribute 2 to the second factor:

$(-2-3i) \cdot (8+4i)$

$(-2-3i)(8+4i)$

Use foil to simplify:

$-16-8i-24i-12i^2$

Replace $i^2$ with -1:

$-16-32i+12$

Combine like terms:

$-4-32i$

----

4th problem:

$(-2-3i)-(4+2i)$

Distribute:

$-2-3i-4-2i$

Combine like terms:

$-2-4-3i-2i$

Simplify:

$-6-5i$

A weight lifter can deadlift 275 pounds. She can increase the weight that she can lift according to the function W(x)=275(1.05)^

suter [353]

Answer:

$350.98\ pounds$

Step-by-step explanation:

we have

$W(x)=275(1.05^{x})$

where

W is the weight in pounds

x is the number of training cycles completed

For $x=5\ cycles$

substitute the value of x in the function

$W(5)=275(1.05^{5})=350.98\ pounds$
