Answer:
[tex](rs)(4) = 8[/tex]
Step-by-step explanation:
Given
[tex]r(x) = 2\sqrt{x[/tex]
[tex]s(x) = \sqrt x[/tex]
Required
Determine [tex](rs)(4)[/tex]
In functions:
[tex](fg)(x) = f(x) * g(x)[/tex]
This implies that:
[tex](rs)(x) = r(x) * s(x)[/tex]
Substitute values for r(x) and s(x)
[tex](rs)(x) = 2\sqrt{x} * \sqrt{x}[/tex]
[tex](rs)(x) = 2(\sqrt{x})^2[/tex]
[tex](rs)(x) = 2x[/tex]
Substitute 4 for x
[tex](rs)(4) = 2 * 4[/tex]
[tex](rs)(4) = 8[/tex]

Answer:
x = 132
Step-by-step explanation:
Angle S = 48 Angle T = 90 Angle W =
180 - 48 = 132
132 - 90 = 42
Angle W = 42
180 - 42 = 132
x = 132

The store offers a 35% discount. If the regular price of an item is x dollars, what is the discount price in dollars?
Answer: .35x
Step-by-step explanation:
take the 35% and turn it into a decimal (.35)
Since the item is "X" dollars, multiply the x(.35)
This gives you .35x
Answer:
If there is a 35% discount, first convert the percent to a decimal
35% = 0.35
Then multiply the discount rate by the price of the item
x = item price
0.20x = discounted price

Find the area of this rectangle.
8 cm
11 cm
Answer:
88 cm squared
Step-by-step explanation:
To find area, you multiply the 2 side lengths with each other. So for this problem, you would do 8 times 11.
Answer:
88 cm
Step-by-step explanation:
The formula to find the area of a rectangle is base × height.
base = 11cm, height = 8cm
11 × 8 = 88cm

Answer:
d=90 e=99 f=81
Step-by-step explanation:
d is a right triangle so its a 90 degree, e is vertical angle so it would be the same as the one ajacent so its 99. F is a linear pair with e so its 81 because 180-99=81.

Solve for N,
−2p + 6n = 5
Answer:
[tex]n=\frac{1}{3}p+\frac{5}{6}[/tex]
Step-by-step explanation:
In this question, you are solving for n.
Solve:
−2p + 6n = 5
We have to get "n" by itself, so add 2p to both sides.
6n = 2p + 5
Since the variable "n" has a number next to it, we have to get rid of that number in order to get our answer.
To do so, we would divide both sides by 6.
[tex]n=\frac{2}{6}p+\frac{5}{6}[/tex]
Simplify the equation further.
[tex]n=\frac{1}{3}p+\frac{5}{6}[/tex]

Answer:
x = 13°
Step-by-step explanation:
Check the diagram attached below to see how the angles labelled A and B, which are interior angles of the triangle where x is found.
Let's find the measure of angle A and angle B.
m<A = 85° (vertical angles are congruent)
m<B = 180° - 98° = 82° (corresponding angles/supplementary angles)
Thus:
x + A + B = 180° (sum of interior angles of a ∆)
x + 85° + 82° = 180° (substitution)
x + 167 = 180
x = 180 - 167 (Subtraction property of equality)
x = 13°
