Find MP.<br><br> MN=17<br> NP=3y<br> MP=5y+9

8_murik_8 [283]

Answer:

$MP = 29$

Step-by-step explanation:

Given:

$MN = 17$

$NP = 3y$

$MP = 5y + 9$

$MN + NP = MP$ (segment addition postulate)

$17 + 3y = 5y + 9$ (substitution)

$3y = 5y + 9 - 17$ (subtracting 17 from each side)

$3y = 5y + 8$

$3y - 5y = 5y - 8 - 5y$ (Subtracting 5y from both sides)

$-2y = 5y - 8 - 5y$

$-2y = - 8$

$y = 4$ (dividing both sides by -2)

$MP = 5y + 9$

Plug in the value of y

$MP = 5(4) + 9 = 20 + 9$

$MP = 29$

Can someone help simplify?: -8x^3y2(2x^4y^4)

Kisachek [45]

So the rule with multiplying exponents of the same base is to add the exponents together. Applying this rule here would look like this:

$-8x^3y^2*2x^4y^4=(-8*2)x^{3+4}y^{2+4}=-16x^7y^6$

In short, your simplified expression is going to be -16x^7y^6.

If sin θ = cos 40°, 0<θ<90°, what is θ?

Bezzdna [24]

Answer:

θ = 50 degrees

Step-by-step explanation:

we have sin θ = cos 40°

θ = arcsin ( cos 40°)

and make sure θ is less than 90 and greater than 0

θ = arcsin (0.766044443)

θ = 50 degrees
