Answer:

2) 30, 70, 80

Step-by-step explanation:

Well there has to be <em>3 angles</em> that all add up to <em>180°</em>.

1)

100+130+130

=360

2)

30+70+80

= 180

3)

25+3+35

=63

4)

45 + 105 + 120

=150

150+120

270

Answer:

see below

Step-by-step explanation:

Thankfully, these inequalities are already simplified, so all we have to do here is graph the inequalities as they are.

To graph y > 2x - 3, first draw the line y = 2x - 3. Make sure to make the line dashed because the sign is ">", which means that the points on the line do not belong to the solution set. Now, we need to figure out which side of the line to shade on. Since the sign is ">", that means that we will shade "above" the line, or on the left side of it. (This is the blue area in the image.)

Repeat a similar process to graph y < x + 1. As usual, first draw the line y = x + 1, and again, make it a dashed line since the sign is "<". And since the sign is "<", that means that we will shade "below" the line, or on the right side of it. (This is the red area in the image.)

The solution set to this system is the area where the two shaded areas overlap, which is the purple area in the image below. Hope this helps!

1. A right triangle has a hypotenuse of length 10 yd and one leg of length 2 yd.
Aleonysh [2.5K]

Question 1.

The Pythagoras Theorem states that the square of the hypotenuse is equal to the sum of the square of the two legs.

h^2=l_1^2+l_2^2

From the question, the hypotenuse is h=10 yd and one of the legs is 2yd.

This implies that,

10^2=l_1^2+ {2}^{2}

Evaluate the exponents

100=l_1^2+ 4

Subbtract 4 from each side

100 - 4=l_1^2

l_1^2 = 96

l_1=  \sqrt{96}

l_1 =  \sqrt{16 \times 6}

l_1 =  4\sqrt{6}

The correct answer is C

Question 2

We want to solve

{e}^{4x}  = 11

using inverse functions.

The inverse of an exponential function is a logarithmic function.

We take natural log of both sides to get;

ln({e}^{4x})   =  \ln(11)

Recall that

\ln( {a}^{n} )  = n  \ln(a)

This means

4x \ln({e})   =  \ln(11)

Logarithm of the base is 1

4x (1)   =  \ln(11)

4x   =  \ln(11)

Divide both sides by 4

x=  \frac{ \ln(11)}{4} \\x=0.5995\\ x = 0.6
