Answer: 15v
Step-by-step explanation: we can combine all the terms since they all have “v” in them making 6+6+3 which is 15, just add “v” to get 15v
F(x)=3x+1 and g(x) = square root of x-1 find (fog)(5)
Answer:
The answer is [15(√x - 1) + 5].
Step-by-step explanation:
(fog)(5) = [3(√x-1) + 1] (5)
= [3(√x - 1) +1] (5)
= 15(√x - 1) + 5

John wrote that 5+5=10. Then he wrote that 5+5+n=10+n. Are the equations John wrote equivalent? Explain (in your solution justify by stating what property of equality he used).
Answer:
They are equivalent
Step-by-step explanation:
n would equal the same, and 10 and 5+5 equal the same. Therefore, whatever n is, they will be equal no matter what. Unless you subtract the n from one side and add on the other.

Identify the inequality that represents the following problem. One less than twice a number is no less than five. What is the solution set?
2 n - 1 > 5
2 n - 1 ≥ 5
1 - 2 n ≥ 5
1 - 2 n > 5
Answer:
is the last one
1 - 2n > 5. The solution set is (-∞, -2)
Step-by-step explanation:
e are dealing here with two problems:
First, to determine which mathematical statement represents "One less than twice a number is no less than five".
Second, solve n, that is, the solution set for the numbers that solve the inequality.
First Part: Identifying the inequality
"One less than twice a number" can be written as , where n is the unknown number.
If it is not less than five, thus it is greater (no less) than five. Then, the symbol here is " > " (greater).
As a result: "One less than twice a number is no less than five" could be rewritten as "One less than twice a number is greater than five", or:
.
Second Part: Finding the solution set
The solution set for this inequality is as follows:
⇒
Subtract -1 from each member of the inequality:
⇒ ⇒
Multiply each member of the inequality by (or divide each member by -2). We have to remember here that when we multiply or divide an inequality by a negative number (-n), this inverts the inequality, that is:
The solution set is then , which is any value less than -2 (not including -2, because is < and not ≤), and we have infinite negative numbers with such a characteristic. We can write it mathematically as an interval notation:
Solution set for is .

What is the midpoint of the segment whose endpoints are (0.4) and (-4,-6)
Answer:
The coordinates of the midpoint are (-2,-1)
Step-by-step explanation:
The Midpoint of a Segment
Given a segment defined by points (x1,y1) and (x2,y2), the coordinates of the midpoint (xm,ym) are calculated as follows:
[tex]\displaystyle x_m=\frac{x_1+x_2}{2}[/tex]
[tex]\displaystyle y_m=\frac{y_1+y_2}{2}[/tex]
We have the endpoints (0,4) and (-4,-6):
[tex]\displaystyle x_m=\frac{0-4}{2}[/tex]
[tex]\displaystyle x_m=\frac{-4}{2}=-2[/tex]
[tex]\displaystyle y_m=\frac{4-6}{2}[/tex]
[tex]\displaystyle y_m=\frac{-2}{2}=-1[/tex]
The coordinates of the midpoint are (-2,-1)

what is the distance between the points (2, 5) and (5,7)?
A. 5
B. square root 13
C. square root 10
Answer:
[tex]\sqrt{13}[/tex]
Step-by-step explanation:
The distance formula that gives the distance between two points is given as:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Plugging in our given points, we get:
[tex]d=\sqrt{(5-2)^2+(7-5)^2},\\d=\sqrt{3^2+2^2},\\d=\sqrt{9+4},\\d=\fbox{$\sqrt{13}$}[/tex].

Suppose we have a right triangle with legs of length a and b and hypotenuse of length c. Suppose b=3 and c=5. Then a= , For the opposing angles, we have sin(A)= , cos(A)= , and tan(A)= .
Answer:
Length of right-angle triangle 'a' = 4
b)
[tex]sin(A) = \frac{opposite side}{Hypotenuse} = \frac{a}{c} = \frac{4}{5}[/tex]
[tex]cos(A) = \frac{Adjacent side}{Hypotenuse} = \frac{b}{c} = \frac{3}{5}[/tex]
[tex]tan(A) = \frac{opposite side}{Adjacent side} = \frac{a}{b} = \frac{4}{3}[/tex]
Step-by-step explanation:
Step(i):-
Given b = 3 and hypotenuse c = 5
Given ΔABC is a right angle triangle
By using pythagoras theorem
c² = a² + b²
⇒ a² = c² - b²
⇒ a² = 5²-3²
=25 - 9
a² = 16
⇒ a = √16 = 4
The sides of right angle triangle a = 4 ,b = 3 and c = 5
Step(ii):-
[tex]sin(A) = \frac{opposite side}{Hypotenuse} = \frac{a}{c} = \frac{4}{5}[/tex]
[tex]cos(A) = \frac{Adjacent side}{Hypotenuse} = \frac{b}{c} = \frac{3}{5}[/tex]
[tex]tan(A) = \frac{opposite side}{Adjacent side} = \frac{a}{b} = \frac{4}{3}[/tex]
What is 2896.9874 rounded to the nearest hundredth?
A meal costs $30 before tax and tip. There is a 7% sales tax. After the tax, a 20% tip is added. What is the total after tax and tip?
Answer:
The total is $38.1
Step-by-step explanation:
The tax is $2.1, The tip is $6.
Percentage is the part of the whole expressed in the fraction of hundred.
The total cost of the meal after the tip and tax is $38.1.
What is percentage of a number?
Percentage of a number or ratio expressed in the form of fraction of hundred.
Given information-
The total cost of meal before tax and tip is $30.
The total sales tax is 7%.
The tip added to the cost of meal is 20%.
As, the total sales tax is 7% and cost of the meal is $30. Thus the total sales tax amount is,
[tex]s_t=30\times\dfrac{7}{100} \\s_t=2.1[/tex]
Thus the amount of sales tax is 2.1.
As the the tip added to the cost of meal is 20% and the cost of the meal is 32.1 after the tax. Thus the amount of meal after the 20 % tip is,
[tex]s_t=30\times\dfrac{20}{100} \\s_t=6.00[/tex]
The amount of the tip of the meal after the tax is $6.00.
The cost of meal after the tip and tax is,
[tex]C=30+2.1+6\\C=38.1[/tex]
Hence the total cost of the meal after the tip and tax is $38.1.

Answer:
2[tex]\sqrt{6}[/tex]
Step-by-step explanation:
Using the rule of radicals
[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]
Simplifying the radicals
[tex]\sqrt{96}[/tex]
= [tex]\sqrt{16(6)}[/tex]
= [tex]\sqrt{16}[/tex] × [tex]\sqrt{6}[/tex] = 4[tex]\sqrt{6}[/tex]
[tex]\sqrt{24}[/tex]
= [tex]\sqrt{4(6)}[/tex]
= [tex]\sqrt{4}[/tex] × [tex]\sqrt{6}[/tex] = 2[tex]\sqrt{6}[/tex]
Thus
[tex]\sqrt{96}[/tex] + 2[tex]\sqrt{6}[/tex] - 2[tex]\sqrt{24}[/tex]
= 4[tex]\sqrt{6}[/tex] + 2[tex]\sqrt{6}[/tex] - 4[tex]\sqrt{6}[/tex] ← collect like terms

Using a pencil, pair of compasses and ruler, construct a triangle with sides 8cm, 9cm and 6cm
Measure the size of the angle between the 8cm and 9cm sides to the nearest degree.
Answer:
The nearest degree of the angle between the 8cm and 9cm sides is:
41°Step-by-step explanation:
To obtain the correct angle in a small triangle like the triangle formed with the measures in the exercise is a little bit hard, in a change of this, I used a triangle calculator, with this I obtained the right angle formed by the sides with 8 cm and 9 cm, which I'm gonna add like an attachment.
From this image, you can guide yourself to draw the triangle without mistakes and to identify the right angle, which is 40,8° but the compass is not so defined, by this reason you can take it like 41° or 40°.

Answer:

Multiply both sides by 9 ( the LCM of 3 and 9 ) to clear the fractions
3a = 7 ( divide both sides by 3 )

One side of each pentagon lies along a side of the octagon.
AB is a side of the octagon.
AC is a side of one of the pentagons.
BC is a side of the other pentagon.
Work out the size of angle y.
Show your working clearly.
Answer:
The size of angle y is 126°
Step-by-step explanation:
From the diagram of the regular polygons, we have;
One side of each pentagon lies along a side of the octagon
The interior angle of the octagon > The interior angle of the pentagon
Each interior angle of a regular pentagon = 108°
Each interior angle of a regular octagon = 135°
Therefore, ∠ABC = 135° - 108° = 27°
Similarly, ∠BAC = 135° - 108° = 27°
Therefore, by triangle the angle sum theorem, we have;
∠y = ∠ACB = 180° - ∠BAC - ∠ABC = 180° - 27° - 27° = 126°
The size of angle y, ∠y = 126°.

Which expression is equivalent to (144k2r14)1/2 for all positive values of k and r ?
A.144kr7
B.12kr7
C.12k2r4
D.72k2r14
Answer:
12kr⁷ is the equivalent expression.
Step-by-step explanation:
We need to find an expression that is equivalent to [tex](144k^2r^{14})^{1/2}[/tex]
We know that, 12² = 144
[tex](144k^2r^{14})^{1/2}=(12^2\times k^2\times r^{14})^{1/2}\\\\=12^{2\times \dfrac{1}{2}}\times k^{2\times \dfrac{1}{2}}\times r^{14\times \dfrac{1}{2}}\\\\=12\times k\times r^7\\\\=12kr^7[/tex]
So, the equivalent expression is [tex]12kr^7[/tex]. Hence, the correct option is (B).
