Answer:
(r * g)(x) =30xx + 6x
if it was composition
r (q(x)) = 5(6x) + 1 = 30x + 1
Step-by-step explanation:
Q(x)=6x and r(x)=5x+1
Find (r•q)(x)
multiplying the functions, right? not composition of functions.
(r * g)(x ) = (5x + 1) * 6x = 30xx + 6x

AB is a diameter of a circle, center O. C is a point on the circumference of the circle, such that
CAB = 26°
What is the size of CBA?
A. 26
B. 45
C. 64
D. 74
Given:
AB is the diameter of a circle.
m∠CAB = 26°
To find:
The measure of m∠CBA.
Solution:
Angle formed in the diameter of a circle is always 90°.
⇒ m∠ACB = 90°
In triangle ACB,
Sum of the angles in the triangle = 180°
m∠CAB + m∠ACB + m∠CBA = 180°
26° + 90° + m∠CBA = 180°
116° + m∠CBA = 180°
Subtract 116° from both sides.
116° + m∠CBA - 116° = 180° - 116°
m∠CBA = 64°
The measure of m∠CBA is 64°.
The size of angle CBA is 128 degrees.
Explanation:To find the size of CBA, we can use the fact that angles in a triangle add up to 180 degrees. Since AB is a diameter, it divides the circle into two semicircles, and angle CAB is an inscribed angle that is half the measure of the central angle.
Therefore, m(CAB) = 26 degrees, and m(CBO) = 2 * 26 = 52 degrees. Since angle CBA is an exterior angle of triangle CBO, it is equal to the sum of the remote interior angles, which is 180 - 52 = 128 degrees.
So, the size of CBA is 128 degrees. The answer is option D. 74.

on the number line which point is closest to pie
The point on a number line that is closest to Pi (π), which is approximately 3.14, would be the point representing either 3 or 4 as they are the closest whole numbers. However, a point representing 3.14 or a closer approximation would be even nearer.
Explanation:The question is asking to identify which point on a number line is closest to Pi (π), a mathematical constant that approximately equals 3.14. On a number line, you can visualize numbers as points. As Pi is 3.14 approximately, the closest point to Pi on a number line would naturally be the point that represents 3 or the point representing 4, as these are the two closest whole numbers to 3.14. However, if there's a point representing the value 3.14, or even closer approximation like 3.141, it would be even closer to Pi than the points representing 3 or 4.

A cone has a slant length of 5 and a diameter of 4. What is the volume of the cone? Use π ≈ 3.14.
A.12.56 cubic units
B.18.84 cubic units
C.20.93 cubic units
D.25.12 cubic units
The volume of the cone, calculated using the given slant length and diameter, is approximately 18.84 cubic units, therefore the correct answer is B. 18.84 cubic units.
Explanation:The subject of this question is the volume of a cone. In order to calculate the volume of a cone, you need to use the formula: V = 1/3πr²h. However, in this case, you are given the slant length and the diameter. First, we need to find the radius (r) and the height (h) of the cone. The radius would be half the diameter, so r = 4/2 = 2. Then, from the given slant length (s) and radius (r), we can find the height by using Pythagoras' theorem: h = sqrt(s² - r²) = sqrt(5² - 2²) = sqrt(21). Now we can substitute r and h into the volume formula: V = 1/3*3.14*2²*sqrt(21) which is approximately 18.84 cubic units. So the answer is option B.18.84 cubic units.

A cylindrical fish tank at the zoo has a capacity of 7252 cubic feet.
What is the height of the tank if its radius is 16 feet?
Use pi = 3. 14 and round to the nearest foot.
Answer: The height of the tank is 9.02 feet
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a cylinder = π radius² x height
Replacing with values given:
7252 = 3.14 ( 16 )² h
Solving for h (height)
7252 / 3.14(16)² =h
7252 /3.14 (256) =h
7252 / 803.84 = h
9.02 =h
The height of the tank is 9.02 feet

Sue makes 50 litres of green paint by mixing litres of yellow paint and litres of blue paint in the ratio 1:4. Yellow paint is sold in 5 litre tins and each tin of yellow paint costs £38. Blue paint is sold in 10 litre tins and each tin of blue paint costs £58. Sue sells all the green paint she makes in 10 litre tins at £89.32 per tin. Work out Sue's percentage profit on each tin of green paint she sells.
Answer:
Sue's percentage profit = 9% on each tin of green paint she sells.
Step-by-step explanation:
Litres of green paints mixed = 50 litres
Ratio of litres of yellow paint and litres of blue paint = 1:4.
To determine the litres of yellow paint, we say:
[tex]yellow \: paint = \frac{1}{4} \times 50 = 10 \: litres[/tex]
To determine the litres of blue paint, we say:
[tex]blue \: paint = \frac{4}{5} \times 50 = 40 \: litres[/tex]
Since yellow paint is sold in 5 litres per tin and each tin cost £38; she has 10 litres of yellow paint in all. That implies that she has 10/5 = 2 tin of yellow paint. If one tin cost £38; 2 tin cost 2 × £38 = £76
Similarly,
Since blue paint is sold in 10 litres per tin and each tin cost £58; she has 40 litres of blue paint in all. That implies that she has 40/10 = 4 tin of blue paint. If one tin cost £58; 4 tin cost 4 × £58 = £232
Total cost of yellow and blue paints = £232 + £76
= £308
Since Sue sells all the green paint she makes in 10 litre tins at £89.32 per tin and she has 50 litres in all; we say: 50/10 litres = 5 tins = 5 × £89.32 = £446.60.
Thus, selling price of the green paint = £446.60
[tex]profit \: \% = \frac{selling \: price - cost \: price}{cost \: price} \times \frac{100}{1} [/tex]
[tex]profit \: \% = \frac{446.60 - 308}{308} \times \frac{100}{1} [/tex]
[tex]profit \: \% = \frac{138.60}{308} \times \frac{100}{1} [/tex]
[tex]profit \: \% = 0.45 \times 100[/tex]
[tex]profit \: \% = 45\%[/tex]
Sue's percentage profit for selling all the tins of green paint is 45%, having sold 5 tins. Therefore, Sue's percentage profit for selling each of the paint will be:
[tex]profit \: \% \: on \: each \: green \: tin = \frac{45}{5} = 9\%[/tex]
Hence, Sue's percentage profit for selling each tin of green paint is 9%.
Proof
9% × 5 tins of green paint = 45%
Final answer:
Sue's percentage profit on each tin of green paint she sells is approximately 44.94%. This is calculated by finding the total cost of inputs, subtracting from the total sales revenue, and then finding the profit ratio to the cost.
Explanation:
To calculate Sue's percentage profit on each tin of green paint she sells, we need to first determine the cost of producing the green paint and then subtract that cost from the selling price. The green paint is produced in a ratio of 1:4 yellow to blue paint, making 50 litres total. Therefore, Sue uses 10 litres of yellow paint and 40 litres of blue paint to make 50 litres of green paint.
Yellow paint costs £38 for a 5-litre tin, so two tins are needed (costing £76 total) to get the required 10 litres. Blue paint costs £58 for a 10-litre tin, so four tins are needed (costing £232 total) to get 40 litres. This brings the total cost to £308 for 50 litres of green paint.
Sue sells her green paint at £89.32 per 10-litre tin. Therefore, for 50 litres, she gets 5 tins x £89.32 = £446.60.
The profit Sue makes is the selling price minus the cost price, which is £446.60 - £308 = £138.60. To find the percentage profit per tin, divide the profit by the cost and multiply by 100:
(£138.60 / £308) x 100 = 44.94%
Therefore, Sue's percentage profit on each tin of green paint she sells is approximately 44.94%.
What is the name of segment AC in the picture? chord, radius, diameter, or circumference
Based on the circle shown above, the name of segment AC include the following: C. diameter.
In Mathematics and Euclidean Geometry, a circle refers to the set of all points in a plane that are located at a fixed distance (radius) from a fixed point.
Generally speaking, the diameter of a circle simply refers to a straight line that passes through the middle (center) to the other end of the circle, thereby, measuring the distance from one end point to another.
This ultimately implies that, the diameter of a circle is double the length of the radius of a circle;

Mr. Woosley is assigning group projects to 24 students. To form the groups, each student will randomly select a slip of paper with the name of a continent on it from a bag. The student will keep the slip of paper. The number of slips of paper in the bag with each continent name is shown below. Africa - 6 Asia - 8 Australia - 4 Europe - 6 What is the probability that a student in Mr. Woosley’s class will not be assigned a project on Australia?
The probability that a student will not be assigned a project on Australia is 20/24, which simplifies to 5/6.
The probability that a student in Mr. Woosley's class will not be assigned a project on Australia can be found by subtracting the probability of being assigned Australia from 1. There are a total of 24 slips of paper representing continents, and 4 of these are Australia. Therefore, there are 24 - 4 = 20 slips that are not Australia.
The probability, P(NOT Australia), is calculated as follows
Calculate the total number of slips: 6 (Africa) + 8 (Asia) + 4 (Australia) + 6 (Europe) = 24.
Determine the number of slips that are not Australia: 24 - 4 (Australia) = 20.
Find the probability: P(NOT Australia) = Number of non-Australia slips / Total number of slips = 20 / 24.
Therefore, the probability that a student will not be assigned a project on Australia is 20/24 or 5/6 when simplified.

About 1/4 of all adults in the United States have type O+ blood. If three randomly selected adults donate blood, find the probability of each of the following events. (Round your answers to four decimal places.) (a) All three are type O+. 0.0156 Correct: Your answer is correct. (b) None of them is type O+. 0.4219 Correct: Your answer is correct. (c) Two out of the three are type O+.
Answer:
a) 0.0156
b) 0.4219
c) 0.1406
Step-by-step explanation:
We are given the following information:
We treat adult having type O+ blood as a success.
P(Adult have type O+ blood) = 0.25
Then the number of adults follows a binomial distribution, where
[tex]P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}[/tex]
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 3
a) All three are type O+
[tex]P(x =3)\\= \binom{3}{3}(0.25)^3(1-0.25)^0\\= 0.0156[/tex]
b) None of them is type O+
[tex]P(x =0)\\= \binom{3}{0}(0.25)^0(1-0.25)^3\\= 0.4219[/tex]
c) Two out of the three are type O
[tex]P(x =2)\\= \binom{3}{2}(0.25)^2(1-0.25)^1\\= 0.1406[/tex]
Using the principle of binomial probability, the probability o the required events are :
All three O positive = 0.0156None O positive = 0.42192 O positive = 0.1406Recall :
P(x = x) = nCx * p^x * q^(n-x) p = probability of success = 1/4 = 0.25q = 1 - p = 1 - 0.25 = 0.75n = number of trials = 3
A.) Probability that all 3 are O+ :
x = 3
P(x = 3) = 3C3 × 0.25³ × 1 = 0.0156
B.) Probability that none 3 are O+
x = 0
P(x = 3) = 3C0 × 1 × 0.75³= 0.4219
C.) Probability that 2 out of the three are O+
x = 2
P(x = 2) = 3C2 × 0.25² × 0.75¹ = 0.1406
Therefore, the required probabilities are : 0.0156, 0.4219 and 0.1406 respectively.

I mean, you can divide the counters by the range 2 - 38.
I only managed to find out that 38 ÷ 2 = 19.
And 38 ÷ 19 = 2.
It says that there are more than 10 counters in each bag.
So 2 bags is the most liable option.
There are 2 bags and 19 counters in each bag.
Answer:
2 bags, 19 counters.
Step-by-step explanation:
This question is looking for factors of 38 with counters being a factor greater ten and the number of bags being the factor that multiplies the counters to get 38. First, find the factors of 38.
1 x 38 = 38
2 x 19 = 38
Since the problem says bags with an s, we can know that there has to be more than one bag. That leaves us with 2 x 19.
