Angle 1 is vertical to 60° meaning that angle 1 is equal to 60°.

All triangles’ angles always add to 180 degrees. Since angle 1 is across from the angle measuring 60 degrees, angle 1 will measure 60 degrees. To find angle 2, you can add 70 and 60, which is equal to 130, and subtract 130 from 180. In other words. Angle 1 would measure 60 degrees and angle 2 would measure 50 degrees. To find angle 3 you can add 60+40=100 and subtract that from 180: 180-100=80 degrees. Hope that helped!

Given f(x)=2x2−5x−3 and g(x)=2x2+x .<br> What is (fg)(x) ?
gizmo_the_mogwai [7]

Answer:

fourth option

Step-by-step explanation:

note that (\frac{f}{g} )(x)x) = \frac{f(x)}{g(x)}

\frac{f(x)}{g(x)} = \frac{2x^2-5x-3}{2x^2+x} ← factorise numerator/ denominator

= \frac{(x-3)(2x+1)}{x(2x+1)} ← cancel the common factor (2x + 1)

= \frac{x-3}{x} where x ≠ 0, - \frac{1}{2}

Find two consecutive numbers whose sum is 117
Serhud [2]
So,

x + y = 117
y = x + 1
x + x + 1 = 117

Collect Like Terms
2x + 1 = 117

Subtract 1 from both sides
2x = 116

Divide both sides by 2
x = 58

y = x + 1

y = 58 + 1

y = 59

The 2 consecutive integers are 58 and 59.

I NEED HELP WITH PRECALC PLEASE
alisha [4.7K]

Answer: First question: D, Second question: A

Step-by-step explanation:

Note: I'm not so good at expanding so I'll just solve it :)

So this leaves either C or D

Apply the sum rule:

8-70=-62

The only one that gives a negative sum is D

For the second picture, the one you have chosen is correct

a1 = 3 and r = -5 so:

an = 3/5 * (-5)^n

Plugging in 8 for n (the first choice) we get the given term: -234,375
