Answer:
B. (0, 4)
Step-by-step explanation:
A function is "increasing" where its slope is positive (up to the right). Here, the graph has positive slope between x=0 and x=4.
The slope is 0 from x=4 to x=7, and the function is decreasing (has negative slope) for x=7 to x=10.
The interval where f(x) is increasing is (0, 4).

Answer:
x° = 40°
Step-by-step explanation:
142° = 3x° + 22° (Vertically opposite angles)
3x° = 120°
x° = 40°
Answer:
The value of x is 40.Step-by-step explanation:
We know that:
142 = 3x + 22 (Vertically opposite angles)Work:
142 = 3x + 22=> 142 - 22 = 3x + 22 - 22=> 120 = 3x=> x = 40Hence, the value of x is 40.

Answer:
A 304.8 cm²
Step-by-step explanation:
lateral area = perimeter of the base × height
perimeter of the base = 2(5.2 cm + 7.5 cm) = 2(12.7 cm) = 25.4 cm
lateral area = 25.4 cm × 12 cm = 304.8 cm²

b. -3(6x^2 +5)/(4(2x^3 +5x +4)^(7/4))
Step-by-step explanation:
a.The function can be evaluated at x = -1/2:
(4(-1/2) -2)/(8(-1/2)^2 +1) = (-2 -2)/(8/4 +1) = -4/3
The limit at x = -1/2 is -4/3.

b.The power rule and chain rule will get you there:

g(x) = (2x^3 +5x +4)^(-3/4)
g'(x) = (-3/4)(2x^3 +5x +4)^(-7/4)(6x^2 +5)
or ...
g'(x) = -3(6x^2 +5)/(4(2x^3 +5x +4)^(7/4))
When we add polynomials, we _____ the coefficients but keep the ______ _______ the same
Answers
Answer:
When we add polynomials, we ADD the coefficients but keep the VARIABLES the same.
Step-by-step explanation:
"coefficients" are the numbers right next to a variable. "Variables" are the letters we use for unknown numbers in a math phrase(expression) or sentence(equation).
So you only add the number besides the variable when the terms have the same variable.
Example:
4x + 3m + 5x + 2m
= 9x + 5m
See we only added the 4 and the 5 bc they were both beside the x and we added the 3 and the 2 bc they were both beside the m. See image for another example.

If m ∥ n, m∠1 = (5x + 12)°, and m∠2 = (7x – 16)°, what is m∠3?
Answers
Answer:
98°
Step-by-step explanation:
m∠1 = m∠2
5x + 12 = 7x - 16; substitute the given
2x = 28
x = 14
m∠2 + m∠3 = 180; supplementary angles
82 + m∠3 = 180
m∠3 = 180 - 82
m∠3 = 98 degrees
Answer: m<3 = 98
Explanation: If two parallel lines are cut by a transversal,
then alternate interior angles are congruent.
This means that the m<1 = m<2.
So we can setup the equation 5x + 12 = 7x - 16
and solving this equation gives us x = 14.
Now let's use <2 to help us find the m<3.
Since x = 14, we can plug a 14 into the equation for x
to find the m<2 and this gives us 7(14) - 16 which is 82.
Now, we know that <2 and <3 form a straight
angle which is equal to 180 degrees.
So we can say that 82 + m<3 = 180 and we find that m<3 = 98.
Alma pays $26.88 each week for gas and $24.95 every three months to change the oil in her car. how much does Alma pay in total for these every year?
Answers
Answer:
1,497.06
Step-by-step explanation:
1,397.26 in gas, cuz 52 weeks in a year (sorry if I multiplied wrong), and $99.80 for oil, cuz 12 months in a year. So the total is 1,497.06
Answer:
$1497.56
Step-by-step explanation:
There are 52 weeks in a year.
$26.88 * 52 = $1397.76
Alma pays $24.95 every 3 months on oil so she does this 4 times a year.
$24.95 * 4 = $99.8
$1397.76 + $99.8 = $1497.56

find the nominal rate of 22% compounded every 3 months

Answers
Using compound interest, it is found that the nominal rate is of 23.88%.
What is compound interest?The amount of money earned, in compound interest, after t years, is given by:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
In which:
A(t) is the amount of money after t years. P is the principal(the initial sum of money). r is the interest rate(as a decimal value). n is the number of times that interest is compounded per year. t is the time in years for which the money is invested or borrowed.The nominal rate is:
[tex]n_r = \left(1 + \frac{r}{n}\right)^n - 1[/tex]
In this problem:
Rate of 22%, hence [tex]r = 0.22[/tex].Compounded every 3 months, hence [tex]n = \frac{12}{3} = 4[/tex].Then, the nominal rate is:
[tex]n_r = \left(1 + \frac{0.22}{4}\right)^4 - 1 = 0.2388[/tex]
The nominal rate is of 23.88%.

total cost, C (in dollars), for fixing a drain that takes h hours is given by the following.
C=76 +24h
Answer the following questions.
(a) If the plumber charged a total of $364, how many hours did she spend
fixing the drain?
(?hours
(b) What is the total cost for fixing a drain that takes 6 hours?
so $?
Answers
Answer:
(a) 12 hours
(b) $220
Step-by-step explanation:
(a) First we plug in $364 for C
C=76+24h
364=76+24h
Subtract 76 from both sides
24h=288
Divide both sides by 24
h=12
She spent 12 hours fixing the drain
(b) First we plug 6 hours in for h
C=76+24(6)
Multiply it out
C=76+144
Add
C=220
It costs $220 for fixing a drain that takes 6 hours

Triangle ABC: sin(45) = BC/6√2 => BC = (6√2)sin(45)
so x/cos(60) = (6√2)sin(45)
x/(1/2) = (6√2)(√2/4)
x/2 = 12/4
x = 2(3)
x = 6
