Answer:
x = 10
[tex] m\angle DCE=55\degree [/tex]
Step-by-step explanation:
Since, CE bisects angle DCF, therefore:
[tex] m\angle ECF= m\angle DCE[/tex]
[tex] 6x-5=4x + 15 [/tex]
[tex] 6x-4x=5 + 15 [/tex]
[tex] 2x=20 [/tex]
[tex] x=\frac{20}{2} [/tex]
[tex] x=10[/tex]
[tex] m\angle DCE=(4x+15)\degree [/tex]
[tex] m\angle DCE=(4\times 10+15)\degree [/tex]
[tex] m\angle DCE=(40+15)\degree [/tex]
[tex] m\angle DCE=55\degree [/tex]

Jeffrey's birthday cost $21, plus an additional $2 for each guess he invites. How many guests can there be, at most, if jeffrey can afford to spent a total of $131 on his birthday party?
Answers
Answer:
55 guests
Step-by-step explanation:
131 = 21 + (2x)
subtract 21 from both sides
110 = 2x
x = 55 guests
Answer:
55 guests
Step-by-step explanation:
if he can afford to spend a total of $131, then you subtract the birthday cost ( $21 ) and divide the answer of those two ( $110 ) by $2 ( the amount for each guest ) which is 55, therefore, 55 is the largest number of guests Jeffrey can afford.

The cost of producing x units of a certain commodity is c() - 1000 +370x + 7x2,
What is the average rate of change of C with respect to x when the production
level is raised from x= 100 to x= 120?
Answers
Step-by-step explanation:
cost to produce 120 units
= C(120) = 1000+5.7(120) + .7(120^2) =
= 11764
cost to produce 100 units = C(100)
= 8570
rate of change = (11764-8570)/(120-100)
= 3194/20
= 159.70 dollars/unit
repeat the process for 100 to 101

Step-by-step explanation:
Answer:
20 m
Step-by-step explanation:
The scale factor between the two triangles is 1/10 because of how 3/30 is 1/10.
Therefore we can calculate the height of the tree by multiplying the height of the smaller triangle by 10 to find the height of the tree.
2*10 = 20m

Imagine that you cross out the top-most square for each step of each diagram. The squares not crossed out have the following counts: 1, 4, 9
This is the sequence of perfect squares. So the rule will have us take the number n, and square it to get n^2. Then we add on the squares we crossed out earlier. This explains the "plus 1" at the end to get the answer of n^2+1

How could writing a problem using an exponent be easier to understand than repeated multiplication?
Answers
Answer:
One reason, is because it clearer and easier to read.
Seeing two numbers (3^5) can let you know, in this example, 3x3x3x3x3 is harder to understand than 3^5.
3 is the number being multiplied, and 5 tells you how many times.

Given 6, 8, and 11 as the three sides of a triangle, classify it as one of the following acute, right or obtuse. Please help and thank you
Answers
9514 1404 393
Answer:
obtuse
Step-by-step explanation:
You may remember that side lengths of 3, 4, 5 make a right triangle. Doubling those lengths to 6, 8, 10 will still give a right triangle.
The given triangle has a longest side (11) longer than would be appropriate for a right triangle (10), so the largest angle is larger than 90°.
The triangle is obtuse.
__
Comparison of a triangle to a right triangle with two sides the same is one of several ways the triangle can be classified. You can use the Law of Cosines to find the largest angle, or you can use a triangle solver (as we have below).
In case you don't recall that 3-4-5 makes a right triangle, you can use the Pythagorean theorem to find the longest side of a right triangle with the given shorter sides:
hypotenuse = √(6² +8²) = √100 = 10
Your long side is longer, so your largest angle is larger than 90°.
Law of Cosines:
angle = arccos((6² +8² -11²)/(2·6·8)) = arccos(-21/96) ≈ 102.6°

you wanna start by plugging in what you know.

now simplify.
a^2+4,225=9,025
[subtract 4,225 from both sides]
a^2=4,800
get a by itself by doing the opposite. [square root both sides]

4 (10-x) = 8x + 4
What is x?
Answers
Answer:
3 = x
Step-by-step explanation:
4 (10-x) = 8x + 4
Distribute
40 -4x = 8x+4
Add 4x to each side
40 -4x+4x = 8x+4 +4x
40 = 12x+4
Subtract 4
40 -4 = 12x+4-4
36 = 12x
Divide each side by 12
36/12 = 12x/12

Find the net change in the value of the function between the given inputs. h(t) = t2 + 2; from −5 to 8
Answers
Answer:
39
Step-by-step explanation:
Given the function :
h(t) = t² + 2
From t = 5 to t = 8
when, t = 5
h(5) = 5² + 2
h(5) = 25 + 2
h(t) at t = 5 ; equals 27
when, t = 8
h(5) = 8² + 2
h(5) = 64 + 2
h(t) at t = 8 ; equals 66
Net Change :
h(8). - h(5)
66 - 27 = 39
