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.

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.
Solve each system of equations.
1. 2x - 4y = 20
x = 4
2. y = 6x + 11

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

help me I need this due by today, oh and I will be posting more and would love a explain on this
Answer:
Yes
Step-by-step explanation:
For the first equation all we need to do is distribute 6 to 3x and 5y. 6*3x = 18x and 6*5y = 30y. For the first equation, it will be: 18x + 30y.
The next equation seems hard but it's simple. First you can easily add, 4x and 6x. That will equal 10x. Then from there distribute 2 to 4x and 2y, so do the same thing as before. 2*4x = 8x and 2*2y = 4y. So now our equation looks like this: 10x + 15y + 8x + 4y + 11y. Now all you need to do is add the x's together and the y's together. 10x + 8x = 18x and 15y + 4y + 11y = 30y. Now we have 18x + 30y. Looks the same, and that is true.
Both equations equal 18x + 30y, so therefore the answer is yes or true.

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.

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

Calculate the average rate of change of f(x)=x²-1/x-4 for 2≤x≤6.
Answer:
3/140 or 0.0214
Step-by-step explanation:
[f(2) - f(6)] / 2-6
f(2) = -3/2
f(6) = 35/2
-3/2 ÷ 35/2 = -3/2 × 2/35
= -6/70 or -3/35 (simplified)
-3/35 ÷ -4 = -3/35 × -1/4
= 3/140

Answer: exponential
Step-by-step explanation:
its exponential
count the squares in each one
first is 2 squares
second is 4 squares
third is 8 squares
this is going up exponentially because the first one would be 2^1 the second would be 2^2 and the third would be 2^3
