Step-by-step explanation:
Review the graph of function h(x).
What is lim h(x), if it exists?
Answer:
0
Step-by-step explanation:
because you have to look at what both sides of the graph is doing as it approaches 2.
from the left, we can see the the graph is going down All the way to 0 at x=2.
and from the right side, the graph is going up to 0 at x=2.
therefore the graph is approaching 0.
The limit of h(x) as x tends to 2 is equal to 0.
How to get the limit of h(x) when x tend to 2?
Remember that a limit is not the same as an evaluation, the limit studies the behavior of the function near the value, not in x = 2.
While we can see that h(2) = 3 (we have a jump there). We can see that around x = 2 the function tends to zero.
From that, we conclude that:
[tex]\lim_{x \to \ 2} h(x) = 0.[/tex]
Then the correct option is the first one.

Answer:
50
Step-by-step explanation:
68+62=130 then subract 180-130 and have 50 so x=50
Answer:
x°=50°
Step-by-step explanation:
Because of the Vertical Angle Theorem, the blank angle across from 68° is the same measure. Therefore, since the blank angle is 68°, then x° would be 50° because 180-62-68=50 due to the Triangle Angle Sum Theorem.

Find the intersection points of the linear and quadratic functions shown below f(x)=2x-5 g(x)= x2+2x-21
Answer:
[tex](-4,-13)[/tex] and [tex](4,3)[/tex] the intersection points.
Step-by-step explanation:
Intersection point of two functions is a common point which satisfies both the functions.
Given functions are,
[tex]f(x)=2x-5[/tex]
[tex]g(x)=x^2+2x-21[/tex]
For a common point of these functions,
[tex]f(x)=g(x)[/tex]
[tex]2x-5=x^2+2x-21[/tex]
[tex]-5=x^2-21[/tex]
[tex]0=x^2-16[/tex]
[tex]x^2=16[/tex]
[tex]x=-4,4[/tex]
For [tex]x=-4[/tex],
[tex]f(-4)=g(-4)=2(-4)-5[/tex]
[tex]=-13[/tex]
For [tex]x=4[/tex],
[tex]f(4)=g(4)=2(4)-5[/tex]
[tex]=3[/tex]
Therefore, [tex](-4,-13)[/tex] and [tex](4,3)[/tex] the intersection points.

Step-by-step explanation:
The graph shows the results of tossing two coins 20 times. The two sides of the coin show heads (H) and tails (T). Based on the results, what is the probability that both coins will show heads the next time the coins are tossed? 17 20 Two Coin Toss 8 CON Frequency ONWAY 3 20 HT TH HH IT 3 10
You forgot the picture
The probability that both coins will show heads the next time the coins are tossed is 3/20.
What is probability?Probability is the likelihood that an event will occur and is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
From the graph, Total number of outcomes= 7+6+4+3=20
Outcomes for both head =6
Then, P(HH)= 6/20
=3/10
Hence, probability that both coins will show heads is 3/20.

A wise man once said, "500 reduced by 4 times my age is 188." What is his age?
Answer:
125
Step-by-step explanation:
Answer:
He Is 78 Years Old.
Step-by-step explanation:
a = age
Solve for a in 500 - 4a = 188.
Simplify 500−4a=188.
500−4a=188
500+−4a=188
−4a+500=188
Subtract 500 from both sides.
−4a+500−500=188−500
-4a = -312
Divide both sides by -4.
[tex]\frac{-4a}{-4} =\frac{-312}{-4}[/tex]
a = 78

He Is 78 Years Old.

Teachers were told that next year they would receive a percent increase in their salary. Mrs. Bennett is making $32,000 a year and will receive $2,550.00 more next year. What is the percent increase? Round to the nearest percent. I need this answer ASAP please and thank you!
Answer:
7.97%
Step-by-step explanation:
Given data
Original Salary= $32,000
Increase= $2,550.00
percent increase= increase/original *100
Percent increase= 2,550.00/32000*100
Percent increase= 0.0796875*100
Percent increase= 7.97%
Hence the increase is 7.97%

solve (200 + 200) √100
Answer:
4000
Step-by-step explanation:
200 + 200 {100
400 × 10
4000
Answer:
4000
Step-by-step explanation:
because the 200+200 are in parenthesis that shows that you will need to do it first.
so.. 200+200=400
and now the second part is asking for the square root of 100. We know that 10 times 10 is 100. This means that 10 is the square root of 100.
And for our last step they ask to multiply our two answers.
so 400 x 10= 4000

cos²x - sin²x = 0,66
x = 24.35°
Step-by-step explanation:
Recall that
cos²x - sin²x = cos 2x
which means that
cos 2x = 0.66 ---> 2x = cos^-1 (0.66) = 48.7°
or x = 24.35°
Answer:
x = 24.35, 155.65, 204.35, 335.65 degrees ( for 0 < x < 360 degrees).
Step-by-step explanation:
cos²x - sin²x = 0.66
cos^2 x = 1 - sin^2 x so
1 - sin^2 x - sin^2 x = 0.66
1 - 2sin^2 x = 0.66
2sin^2 x = 1 - 0.66
sin^2x = 0.34/2 = 0.17
sin x = +/- √0.17
= +/- 0.41231
x = 24.35 degrees ( in first quadrant)
and 180 + 24.35 = 204.35 degrees in third quadrant.

Answer:
20°
Step-by-step explanation:
It's a catch. Draw a stronger line (along the circle) from V, going through Z, W, X, and getting to Y. That measures 320°.
Since the whole circle is 360° the segment YV measures 40°. Therefore, angle VXY = 20°.

Answer: c=35
D=90
E=55
Step-by-step explanation:
Since d is a right angle it is 90. Take 90 and subtract it from 180 to get 90.Set them equal to 90 so 3x+11+5x+15=90
Simplify
8x+26=90
8x=64
X=8
Now take x and plug it in for each equation
3(8)+11=35
5(8)+15=55
So measured of c is 35
Measure of e is 55
And d is 90
