f(x)=x^2+8x-10 find f(a)+5
Answer:
We conclude that:
f(a) + 5 = a² + 8a - 5
Step-by-step explanation:
Given
The function is given by
f(x) = x²+8x-10
To determine
f(a)+5
In order to determine f(a)+5, first, we need to determine f(a).
Now substitute x = a in the function f(x) = x²+8x-10
f(a) = (a)² + 8(a) - 10
f(a) = a² + 8a - 10
Thus,
f(a) + 5 = (a² + 8a - 10) + 5
f(a) + 5 = a² + 8a - 5
Therefore, we conclude that:
f(a) + 5 = a² + 8a - 5

Simplify sin θ/cosθ tan θ to a number or a single trigonometric function
Answer:
The answer is below
Step-by-step explanation:
Trigonometric functions are functions used in right angled triangles to relate an angle in the triangle to the ratio of two side. The most common trigonometric functions are the sine, the cosine, and the tangent.
Some trigonometric identities are:
secθ = 1/ cosθ, cosecθ = 1 / sinθ, tanθ = sinθ / cosθ, cotθ = 1 / tanθ = cosθ / sinθ.
Hence simplifying the question:
[tex]\frac{sin\theta}{cos\theta tan\theta} =\frac{sin\theta}{cos\theta *\frac{sin\theta}{cos\theta} }\\\\=\frac{sin\theta}{sin\theta}\\\\=1[/tex]

The two quantitative elements of process variation are: Select one: a. common cause and special cause b. median and variance c. central tendency and spread d. inspection and detection
Answer:
The two quantitative elements of process variation are:
a. common cause and special cause.
Step-by-step explanation:
When a process fails to follow the prescribed process pattern, with reduced productivity, higher costs, longer lead times, and late deliveries, a process variation has occurred. Thus, process variation is a leading cause of quality issues. There are common cause variation, which is inherent in the system itself, and special cause variation, which is caused by external factors outside of the system. Process variations can be reduced by reducing the common and special cause variations, among other steps.
You charge 2500 to a credit card. Use the compound interest formula to find the new amount you owe on your credit card after 6 months 20% APR compounded daily (assuming you don’t make any payments)
Answer: Well This is what 24% APR on a credit card is?
If you have a credit card with a 24% APR, that's the rate you're charged over 12 months, which comes out to 2% per month. Since months vary in length, credit cards break down APR even further into a daily periodic rate (DPR). It's the APR divided by 365, which would be 0.065% per day for a card with 24% APR.

Answer:
[tex]y = 4x - 12[/tex]
Step-by-step explanation:
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which m is the slope and b is the y-intercept(value of x when y = 0).
In this question:
Slope 4, which means that [tex]m = 4[/tex].
So
[tex]y = 4x + b[/tex]
Contains point (1,-8).
This means that when [tex]x = 1, y = -8[/tex]. We replace this into the equation to find b. So
[tex]y = 4x + b[/tex]
[tex]-8 = 4(1) + b[/tex]
[tex]b = -12[/tex]
So
[tex]y = 4x - 12[/tex]

A store in Melrose, Massachusetts advertised a 35-mm camera for $259.99 and a wide-angle lens for $89.99. What is the total purchase price if the state sales tax rate is 6 percent
Answer:
The total purchase price is $370.97.
Step-by-step explanation:
Given;
price of the 35-mm camera, = $259.99
price of the wide-angle lens = $89.99
TAX rate = 6% = 0.06
The total purchase price = 0.06($259.99 + $89.99) + ($259.99 + $89.99)
The total purchase price = $20.99 + 349.98
The total purchase price = $370.97
Therefore, the total purchase price is $370.97.
In a certain town, 23% of males have a beard. In random samples of 25 men from
this town, what are the mean and standard deviation of the number of men with
a beard?
Answer:
Mean μ = 5.75
Standard deviation σ = 2.1041
Step-by-step explanation:
Step(i):-
Given that the size of the sample 'n' = 25
Given proportion p= 23% = 0.23
Let 'X' be the random variable in a binomial distribution
Mean μ = np = 25 × 0.23 = 5.75
Step(ii):-
Standard deviation
σ = √npq
σ = [tex]\sqrt{25 X 0.23 X0.77}[/tex]
σ = 2.1041

The probability of hitting a target is 1/8. What is the probability of hitting the target exactly twice in five tries
Answer:
[tex]P(X=2) = 0.1047[/tex]
Step-by-step explanation:
Represent the probability of hitting the target with H.
So:
[tex]H = \frac{1}{8}[/tex]
Represent the probability of not hitting the target with T.
So:
[tex]T = 1 - H[/tex]
[tex]T =1 - \frac{1}{8}[/tex]
[tex]T =\frac{7}{8}[/tex]
Required
Probability of exactly 2 hits in 5 tries
This probability is a binomial probability and will be calculated using:
[tex]P(X=x) = ^nC_x H^xT^{n-x}[/tex]
In this case:
[tex]x = 2[/tex] i.e 2 hits
[tex]n = 5[/tex] i.e. 5 attempts
So, we have:
[tex]P(X=2) = ^5C_2 H^2T^{5-2}[/tex]
[tex]P(X=2) = ^5C_2 H^2T^3[/tex]
Apply combination formula:
[tex]P(X=2) = \frac{5!}{(5-2)!2!} H^2T^3[/tex]
[tex]P(X=2) = \frac{5!}{3!2!} H^2T^3[/tex]
[tex]P(X=2) = \frac{5*4*3!}{3!2*1} H^2T^3[/tex]
[tex]P(X=2) = \frac{5*4}{2} H^2T^3[/tex]
[tex]P(X=2) = 10* H^2T^3[/tex]
Substitute values for H and T
[tex]P(X=2) = 10* (\frac{1}{8})^2(\frac{7}{8})^3[/tex]
[tex]P(X=2) = 10* \frac{1}{64}*\frac{343}{512}[/tex]
[tex]P(X=2) = \frac{3430}{32768}[/tex]
[tex]P(X=2) = 0.1047[/tex]
Hence, the probability of 2 hits in 5 tries is 0.1047
Tyre measured the average monthly temperature in degrees Fahrenheit for several months. If February is set ect 2 and June is oud to 6 what function best models these data from February to June?
Answer:
it will be d
Step-by-step explanation:
Answer:
f(x)=11x+12
Step-by-step explanation:
it shows that the intercept is around halfway between 0 and 20, and the plots are not exactly at the 10s marks, if you look- June is supposed to be 6, but it’s closer to 66. since 6*11=66, i’d say 11x+12 is the answer.
