If p(x) = 2x - 5 and r(x) = 3x + 4, calculate (pr)(x).
A
6x2 - 7x - 20
B
6x2 + 7x - 20
5x - 1
D
6x2 - 20
Answer:
6x + 3
Step-by-step explanation:
Given p(x) = 2x - 5 and r(x) = 3x + 4,
p(r(x)) = p(3x+4)
p(3x+4) = 2(3x+4) - 5
p(3x+4) = 6x + 8 - 5
p(3x+4) = 6x +3
Hence the composite function (pr)(x) is 6x + 3
which pair of angles are supplementary?
Answer: H
Step-by-step explanation:

Routine and non routine problems involving integers
six ALS learners share an apartment.They had a balance bill of 1,800 for the month of June. How much do they each to contribute?
Answer:
each one contribute 300
Step-by-step explanation:
The computation of the each one contribution is given below:
Given that
There are six ALS learner who shares the apartment
The total bill is 1,800
So based on the above information, the each one contribution is
= Total bill ÷ number of learners
= 1,800 ÷ 6
= 300
Hence, each one contribute 300
a rectangular prism has a volume of 104 cubic inches the prism has a height of 2 inches and a width of 4 inches what is the length of the prism
Answer:
13inches
Step-by-step explanation:
formula for volume of rectangular prism is, V= whl
where, w is width
h is height
and l is length.
hence, substituting the values,
104=4×2× L
104=8×L
on solving,
L= 13
hence, length is 13 inches
Solve the equation (3x2)(3x4)=36
Answer:
The solution to the equation will be:
[tex]x=\sqrt[3]{2},\:x=-\sqrt[3]{2}[/tex]
or
[tex]x = 1.26[/tex] , [tex]x = -1.26[/tex]
Step-by-step explanation:
Given the expression
[tex]\left(3x^2\right)\left(3x^4\right)=36[/tex]
simplify
[tex]9x^6=36[/tex]
Divide both sides by 9
[tex]\frac{9x^6}{9}=\frac{36}{9}[/tex]
[tex]x^6=4[/tex]
[tex]\mathrm{For\:}x^n=f\left(a\right)\mathrm{,\:n\:is\:even,\:the\:solutions\:are\:}x=\sqrt[n]{f\left(a\right)},\:-\sqrt[n]{f\left(a\right)}[/tex]
[tex]x=\sqrt[6]{4},\:x=-\sqrt[6]{4}[/tex]
solving
[tex]x=\sqrt[6]{4}[/tex]
[tex]=\sqrt[6]{2^2}[/tex]
Apply exponent rule: [tex]\left(a^b\right)^c=a^{bc}[/tex]
[tex]=\sqrt[6]{2^2}=2^{2\cdot \frac{1}{6}}[/tex]
[tex]=\sqrt[3]{2}[/tex]
[tex]= 1.26[/tex]
Thus,
[tex]x=\sqrt[3]{2}[/tex] (or [tex]x = 1.26[/tex] )
similarly solving
[tex]x=-\sqrt[6]{4}[/tex]
[tex]x=-\sqrt[3]{2}[/tex] or ([tex]x = -1.26[/tex])
Therefore, the solution to the equation will be:
[tex]x=\sqrt[3]{2},\:x=-\sqrt[3]{2}[/tex]
or
[tex]x = 1.26[/tex] , [tex]x = -1.26[/tex]
Answer:
[tex]3 {x}^{2} \times 3 {x}^{4} = 36 \\ 9 {x}^{6} = 36 \\ {x}^{6} = 4 \\ \boxed{x = \sqrt[6]{4} }[/tex]
is the right answer.

to produce and is sold for $55. How many pairs of shoes must be sold before the business breaks even?
Answer:
6000 pairs of shoes
Step-by-step explanation:
Well what you have to do is subtract the 5 from the 55 (because that's the profit) and then you get 50. Then divide 300,000 by 50 and you get 6000

Step-by-step explanation:
If f(x)f(x) is an exponential function where f(-0.5)=27f(−0.5)=27 and f(1.5)=21f(1.5)=21, then find the value of f(0.5)f(0.5), to the nearest hundredth.
With f(x) is an exponential function, the value of function f(0.5) is 0.88.
Given that, f(-0.5)=27 and f(1.5)=21.
We know that, general form of exponential function, [tex]f(x)=ab^x[/tex].
Here,
[tex]f(-0.5)=ab^{-0.5}[/tex]
[tex]ab^{-0.5}=27[/tex] -----(i)
Now,
[tex]f(1.5)=ab^{1.5}[/tex]
[tex]ab^{1.5}=21[/tex] -----(ii)
From the equation (i) and (ii), we get
[tex]\frac{ab^{1.5}}{ab^{-0.5}}=\frac{21}{27}[/tex]
[tex]ab^2=0.7778[/tex]
[tex]ab=\sqrt{0.7778}[/tex]
[tex]ab=0.8819[/tex]
Now, [tex]f(0.5)=(0.7778)^{0.5}[/tex]
f(0.5)=0.8819
f(0.5)≈0.88
Therefore, the value of function f(0.5) is 0.88.

Systolic Blood Pressure Assume that the mean systolic blood pressure of normal adults is 120 millimeters of mercury and the standard deviation is 5.6. Assume the variable is normally distributed. Use a TI-83 Plus/TI-84 Plus calculator and round the answers to at least four decimal places.
If an individual is selected, find the probability that the individual's pressure will be between 119.4 and 121.4mmHg
P (119.4 50) =?
Answer:
0.1425 = 14.25% probability that the individual's pressure will be between 119.4 and 121.4mmHg.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
[tex]\mu = 120, \sigma = 5.6[/tex]
Find the probability that the individual's pressure will be between 119.4 and 121.4mmHg
This is the pvalue of Z when X = 121.4 subtracted by the pvalue of Z when X = 119.4. So
X = 121.4
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{121.4 - 120}{5.6}[/tex]
[tex]Z = 0.25[/tex]
[tex]Z = 0.25[/tex] has a pvalue of 0.5987
X = 119.4
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{119.4 - 120}{5.6}[/tex]
[tex]Z = -0.11[/tex]
[tex]Z = -0.11[/tex] has a pvalue of 0.4562
0.5987 - 0.4562 = 0.1425
0.1425 = 14.25% probability that the individual's pressure will be between 119.4 and 121.4mmHg.
