Answer:
(245 / (6^2 - 1)) + 15 = 22
Step-by-step explanation:
Well we need to divide 245 by something - and by something that divides it, otherwise we can't solve this. It's not divisible by 6^2 = 36, it's not divisible by 6^2 - 1 + 15 = 50 and it's not divisible by 6^2 - (1 + 15) = 20. Our only option is (6^2 - 1) = 35
245/35 = 7 and we notice that 7 + 15 = 22, so we've solved it.

1. Ella wants to know how tall the flagpole at her school is, her eye level is 5.5 feet above the ground and she stands 36 feet from the base of the flagpole. If the angle of elevation is 25 degrees, what is the height of the flagpole?
Answers
9514 1404 393
Answer:
22.3 ft
Step-by-step explanation:
The height of the portion of the pole that is above Ella's eyes can be found using the tangent function.
Tan = Opposite/Adjacent
tan(25°) = (height above eyes)/(36 ft)
height above eyes = (36 ft)·tan(25°) ≈ 16.8 ft
Then the height of the flagpole is ...
5.5 ft + 16.8 ft = 22.3 ft
The flagpole is 22.3 feet high.
"For which value of c does Limit of f (x) as x approaches c not exist?"
Answers
The limit does not exist at the jump discontinuity at x = -2.
From the left, the green-ish curve approaches 4; from the right, the orange curve approaches 6. These one-sided limits are not equal, so the two-sided limit does not exist.
A limit of a function does not exist at a point x is the limit of f(x) approaching x to the left is different of the limit of f(x) approaching x to the right.
Using this concept, we find that the limit does not exist at c = -2.
Points we need to verify:
Points in which there are changes in the definition of the function, which are:
x = -4, -2, 2, 4
At x = -4
The definitions are bunched together, so the lateral limits are the same, and the limit exists.
At x = -2
As the function approaches x = -2 to the left(x < -2), its value is close to 4, so the limit is 4.
As the function approaches x = -2 to the right(x > -2), its value is close to 6, so the limit is 6.
Since the lateral limits are different, for c = 2, the limit does not exist, and this is the correct answer.
At x = 2
The lateral limits are the same, the only thing that changes is the definition of the function at x = 2, which does not affect the limit, which exists.
At x = 4
The definitions are bunched together, so the lateral limits are the same, and the limit exists.

Answer:

b) ED = 3.05
Step-by-step explanation:
Triangle ABE is similar to triangle ACD by AA similarity. This means we can write the proportions ...
a) CD/BE = AC/AB
CD = BE(AC/AB) = 3.8(12.3/8.2)
CD = 5.7
__
b) ED/AD = BC/AC
ED = AD((AC -AB)/AC) = 9.15(12.3 -8.2)/12.3
ED = 3.05

A baseball player hit 345 out of 1,000 balls pitched to him. What are the chances he gets a hit when he steps up to the plate?
Answers
Answer:
0.345
Step-by-step explanation:
hits/at-bats = 345/1000 = 0.345
The probability of a hit, any particular time he goes to bat. is 0.345.
The problem does not request any particular format, so 0.345 is a perfectly good answer.
In baseball, that is called a 'batting average', and is actually expressed that way - as a decimal - in a player's statistics.
On the other hand, if we did want to express the probability as a percentage, we would do this:
0.345 * 100% = (0.345 * 100) % = 34.5 %
Hope this helps

Estimate a 10% tip on a bill of $132.17 by first rounding the bill amount to the nearest ten dollars.
Answers
Answer:
Tip= $13
Step-by-step explanation:
Giving the following information:
Tip rate= 10% = 0.1
Bill= $132.17
First, we need to round the bill by the nearest ten dollars. In this case, we round to the lower tenth:
Bill= 132.17 = 130
Now, we can determine the tip:
Tip= bill*tip rate
Tip= 130*0.1
Tip= $13

If y=x2+3x, then the average rate of change of y with respect to x over the closed interval 1
Answers
Answer:
[tex]Rate = 19[/tex]
Step-by-step explanation:
Given
[tex]y = x^2 + 3x[/tex]
[tex]1 \le x \le 15[/tex]
Required
Determine the average rate of change
This is calculated as:
[tex]Rate = \frac{f(b) - f(a)}{b - a}[/tex]
Where
a = 1 and b = 15
So, we have:
[tex]Rate = \frac{f(15) - f(1)}{15 - 1}[/tex]
[tex]Rate = \frac{f(15) - f(1)}{14}[/tex]
Solve f(15):
[tex]f(15) = 15^2 + 3*15 = 270[/tex]
Solve f(1)
[tex]f(1) = 1^2 + 3*1 = 4[/tex]
So:
[tex]Rate = \frac{f(15) - f(1)}{14}[/tex]
[tex]Rate = \frac{270- 4}{14}[/tex]
[tex]Rate = \frac{266}{14}[/tex]
[tex]Rate = 19[/tex]
Find x
X + 50

Explanation:

x + x = 120
x = 120/2
x= 60
Hope it’s right
Best luck with your studying
Answer:
x = 60
Step-by-step explanation:
(x + 50)° + (x + 10)° = 180° (interior angles on the same side of transversal)
(2x + 60)° = 180°
2x + 60 = 180
2x = 180 - 60
2x = 120
x = 120/2
x = 60

Answers
Answer:
A small publishing company is planning to publish a new book. The production costs will include one-time fixed costs (such as editing) and variable costs (such as printing). The one-time fixed costs will amount to $17,750 . The variable costs will be $12.75 per book.
Step-by-step explanation:
The equation that should be related P to N is 13.75N - 550.
Calculation of the equation:Since The total production cost (in dollars) is given by the function c = 19.95N+550, where N is the number of books. The total revenue earned (in dollars) from selling the books is given by the function R= 34.60N.
So here the equation could be
Profit = Revenue - cost
= 33.70N - 19.95N - 550
= 13.75N - 550
hence, The equation that should be related P to N is 13.75N - 550.
