Answer:

4) y+2 = 3(x+1)

5) y+2 = -1(x-1)

6) y+3 = 0(x-2) OR y=3

Step-by-step explanation:

M is given and is the slope

X and Y change signs (positive becomes negative and vice versa)

If m∠UNR = 180° find m∠RNS<br> A. 27°<br> B. 34°<br> C. 59°<br> D. 94°

LenaWriter [7]

Answer:

Option A) m∠RNS=27°

Step-by-step explanation:

We know that $m$ ∠UNR = 180°. This tells us that the Sum of the enclosed angles should equal 180°, by trigonometry. So the enclosed angles are:

$m$ ∠RNS = $(3x+6)^{o}$

$m$ ∠SNT= $(13x+3)^{o}$

$m$ ∠TNU= $(10x-11)^{o}$

Now let us add all the angles and solve for the value of $x$ as follow:

$m_{RSN}+m_{SNT}+m_{TNU}=m_{UNR}\\\\(3x+6)+(13x+3)+(10x-11)=180\\\\3x+13x+10x+6+3-11=180\\\\26x-2=180\\\\26x=180+2\\\\26x=182\\\\$

$x=\frac{182}{26} \\\\x=7$

Now lets plug in the value into the expression for angle $m$ ∠RNS to find the angle as:

$RNS = (3x+6)^{o}\\\\RNS=(3(7)+6)^{o}\\\\RNS=(21+6)^{o}\\\\RNS=27^{o}$

Thus Option A. is the correct answer.

A 30-m tall building casts a shadow. The distance from the top of the building to the tip of the shadow is 32 m. Find the length

zepelin [54]

Answer: 11.1 m

Step-by-step explanation:

This can be solved by the Pythagorean theorem where;

c² = a² + b²

c is the hypotenuse which is the distance from the top of the building to the tip of the shadow.

a is the height

c is the length

32² = 30² + b²

b² = 32² - 30²

b² = 1,024 - 900

b² = 124

b = √124

b = 11.1 m

Mohsin purchased a 30 ounce bag of dried Turkish figs for $11.40. What is the cost per pound?

valentinak56 [21]

Answer:

$6.08 per pound

Explanation:

30 ounce ⇒ $11.40

conversions:

16 ounce ⇔ 1 pound

1 ounce ⇔ 0.0625 pound

solve:

0.0625(30) pound ⇒ $11.40

1.875 pound ⇒ $11.40

1 pound ⇒ $6.08

(-6x3-4x2-8)+(x3-x2-9x+4) add together and simply

Aleksandr [31]

Answer:

-5x³ -5x² -9x - 4

Step-by-step explanation:

(-6x³-4x²-8)+(x³-x²-9x+4)

Add the like terms.

-6x³ and x³ are like terms. -6x³ + x³ = -5x³

-4x² and -x² are like terms. -4x² - x² = -5x²

-8 and 4 are like terms. -8 + 4 = -4

-6x³-4x²-8 +x³-x²-9x+4 = -5x³ -5x² -9x - 4
