Answer:
sometimes true
Step-by-step explanation:
The equation reduces to ...
x^y·x^z = z^18
x^(y+z) = z^18
This is not true in general, but is true for specific cases of x, y, and z. For example,
4^(7+2) = 2^18 . . . . (x, y, z) = (4, 7, 2)
4^(7+0) ≠ 0^18 . . . . (x, y, z) = (4, 7, 0)
The equation is sometimes true.

Answer:

Step-by-step explanation:
3p - 1 = 5(p-1) -2(7-2p)
(simplify)
3p -1 = 5p-5-14+4p
3p-1 = 9p-19
(make p the subject)
3p-9p = -19+1
-6p = -18
p = -18/-6
p = 3
es 6
Step-by-step explanation:
3p-1= 5p-5-14mas4p
3p-4p-5p= -5-14mas1
3p-4p-5p= -18
3p-9p=-18

Answer:
A. There were 8 people who rode in the bicycle race.
Step-by-step explanation:
The line plot in the picture shows the distance in miles raced by Sophie's friends.
It's required to select one of the following options:
A. There were 8 people who rode in the bicycle race.
Since each x represents one person, and there are 8 x's, this statement is true.
B. More people rode 3/4 of a mile than 1/4 of a mile. There is only one x in 3/4 and 3 x's in 1/4. This is false
C. This option is false also, there were 5 people who rode 1/4 of a mile or 2/4 of a mile.
D. There were 2 people who rode 1 mile. False

Problem 11-15 Using CAPM A stock has an expected return of 10.5 percent, a beta of 1.55, and the expected return on the market is 8.5 percent. What must the risk-free rate be? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.G., 32.16.)
Answer:
the risk free rate of return is 4.86%
Step-by-step explanation:
The computation of the risk free rate is shown below;
As we know that
Expected return = Risk free rate of return + Beta × (Market rate of return - risk free rate of return)
10.5% = Risk free rate of return + 1.55 × (8.5% - Risk free rate of return)
10.5% = Risk free rate of return + 13.175% - 1.55 Risk free rate of return
10.5% - 13.175% = -0.55 risk free rate of return
-2.675% = -0.55 risk free rate of return
So, the risk free rate of return is
= 2.675% ÷ 0.55
= 4.86%
Hence, the risk free rate of return is 4.86%
A consignment of eggs was delivered damaged with 72 eggs being cracked, which is 12 percent of the total consignment. Calculate the total amount of eggs in the consignment. Find the answer.
Answer:
There were 600 eggs in total.
Step-by-step explanation:
In order to find the total amount of eggs we need to divide the percent by the eggs cracked.
First we need to convert 12% to a decimal, 0.12.
Now we need to divide the cracked eggs by the percent.
So:
72 ÷ 0.12 = 600
A rectangular pool has a sidewalk around it. The pool measures 6 feet by 10 feet and the total area of the pool and sidewalk is 96 square feet. What is the width of the sidewalk?
Answer:
width of the sidewalk = 1 feet
Step-by-step explanation:
Area of the pool = length × width
Length = 10 feet
Width = 6 feet
Area of the pool = length × width
= 10 feet × 6 feet
= 60 feet²
Area of the pool = 60 feet²
Total area = Area of the pool + Area of sidewalk
96 feet² = 60 feet ² + Area of sidewalk
Area of sidewalk = 96 feet² - 60 feet ²
Area of sidewalk = 36 feet²
Length of pool + sidewalk = 10 + 2x
width of pool + sidewalk = 6 + 2x
( 10 + 2 x ) ( 6 + 2 x ) -60 = 36
60 + 20x + 12x + 4x² - 60 = 36
4x² + 32x - 36 = 0
4x² + 36x - 4x - 36 = 0
4x (x + 9) -4(x + 9) = 0
(4x - 4) (x + 9) = 0
4(x - 1) (x + 9) = 0
(x - 1) = 0 (x + 9) = 0
x = 1 or x = -9
The width of the side walk can't be a negative value
Therefore, width of the sidewalk = 1 feet
A rectangular pool has a sidewalk around it. Width of the sidewalk is 1 feet.
Given
A rectangular pool has a sidewalk around it. The pool measures 6 feet by 10 feet and the total area of the pool and sidewalk is 96 square feet.
Let 'w' be the width of sidewalk
The pool measures 6 feet by 10 feet . The width of the rectangular pool with side walk is 6+x+x=6+2x
The length of the rectangular pool with side walk is 10+2x
The total area of the pool and side walk is length times width
Total area= [tex](6+2x)(10+2x)\\[/tex]
[tex]96=(6+2x)(10+2x)\\96=60+32x+4x^2\\60+32x+4x^2-96=96-96\\4x^2+32x-36=0[/tex]
apply quadratic formula to solve for x
[tex]x=\frac{-32\pm \sqrt{32^2-4\cdot \:4\left(-36\right)}}{2\cdot \:4}\\x=\frac{-32\pm \:40}{2\cdot \:4}\\x= \frac{-32+40}{2\cdot \:4}=1\\x=\frac{-32-40}{2\cdot \:4}=-9[/tex]
Width of the sidewalk cannot be negative
so the width of the sidewalk is 1 feet

Answer:
(a) The zeroes of f(x) are rational numbers
(b) The smallest integer value of a is 3
Step-by-step explanation:
In the quadratic function f(x) = ax² + bx + c, we can know the number and the types of its roots using the discriminant Δ, where Δ = b² - 4ac
If Δ > 0, then the zeroes are two different real numbersIf Δ = 0, then the zeroes are the same real numberIf Δ < 0, then the zeroes are imaginary numbersNote: In the first case if Δ is a perfect square number then the zeroes are rational, if not then the zeroes are irrational
(a)
∵ The equation function is f(x) = ax² + 11x + 12
∵ a = 2
∴ a = 2, b = 11 and c = 12
→ Substitute them in the rule of Δ
∵ Δ = (11)² - 4(2)(12) = 121 - 96
∴ Δ = 25
∵ Δ > 0
∴ f(x) has two different real zeroes
∵ 25 is a perfect square number
→ That means the zeroes of the function are rational numbers
∴ The zeroes of f(x) are rational numbers
(b)
∵ f(x) ha imaginary zeroes
→ By using the third rule above
∴ Δ < 0
∵ a = a, b = 11 and c = 12
→ Substitute them in the rule of Δ
∴ (11)² - 4(a)(12) < 0
∴ 121 - 48a < 0
→ Add 48a to both sides
∵ 121 - 48a + 48a < 0 + 48a
∴ 121 < 48a
→ Divide both sides by 48
∴ 2.52083 < a
∴ a > 2.52083
∵ The smallest integer greater than 2.52083 is 3
∴ The smallest integer value of a is 3

solve this equation 3.5z – 2.7z = –6
Answer:
z=-7.5
Step-by-step explanation:
Answer:
z = -7.5
Step-by-step explanation:
First you have to simplify the equation:
0.8z = -6
Then you have to isolate the z, and to do so you have to divide both sides by 0.8.
0.8/0.8z = -6/0.8
The answer then comes out to be z = -7.5
Kite E F G H is inscribed in a rectangle. Points F and H are midpoints of sides of the rectangle, and creates a side length of x. Lines are drawn from point F to point H and from point E to point G and intersect at a point. Line E G is parallel to a rectangle side. The distance from point F to the intersection is 2, and the distance from H to the intersection is 5. Kite EFGH is inscribed in a rectangle where F and H are midpoints of parallel sides. The area of EFGH is 35 square units. What is the value of x? 4 units 5 units 6 units 7 units
Answer:
5 units
Step-by-step explanation:
Let point O be the point of intersection of the kite diagonals.
|OF| = 2, |OH| = 5
|FH| = |OF| + |OH| = 2 + 5 = 7
FH and EG are the diagonals of the kite. Hence the area of thee kite is:
Area of kite EFGH = (FH * EG) / 2
Substituting:
35 = (7 * |EG|) / 2
|EG| * 7 = 70
|EG| = 10 units
The longer diagonal of a kite bisects the shorter one, therefore |GO| = |EO| = 10 / 2 = 5 units
x = |GO| = |EO| = 5 units
Answer:
5 units
