If x² = y³ , for what value of z does [tex]x^{3z}[/tex] = [tex]Y^{9}[/tex] ?
Answer:
z= 2
Step-by-step explanation:
To solve the question given, we will follow the steps below;
[tex]X^{3z}[/tex] = [tex]Y^{9}[/tex] -----------------------------------------------------------------(1)
but applying the law of indices mᵃᵇ = (mᵃ)ᵇ
then
[tex]Y^{9}[/tex] = [tex](Y^{3})^{3}[/tex]
replace [tex]Y^{9}[/tex] by [tex](Y^{3})^{3}[/tex] in equation (1)
[tex]X^{3z}[/tex] = [tex]Y^{9}[/tex]
[tex]X^{3z}[/tex] = [tex](Y^{3})^{3}[/tex] --------------------------------------------------------------------(2)
but from the question x² = y³
replace y³ by x² in equation (2)
[tex]X^{3z}[/tex] = [tex](Y^{3})^{3}[/tex]
[tex]X^{3z}[/tex] = [tex](X^{2})^{3}[/tex]
[tex]X^{3z}[/tex] = [tex]X^{6}[/tex]
3z = 6
divide both-side of the equation by 3
3z/3 = 6/3
On the left-hand side of the equation, 3 at the numerator will cancel-out 3 at the denominator leaving us with just z while on the right-hand side of the equation 6 will be divided by 3
z= 2
find the values for a and b.
Answer:
the value of a and b is 68
Step-by-step explanation:
the other half is 224 so you minus 360 from 224 which will give us 136 then you divide by 2 to get a and b.
Answer:
a = 68, b = 136
Step-by-step explanation:
The angle in the circle = 360°, thus
b = 360 - 224 = 136
The inscribed angle a between a tangent- chord is equal to half the measure of its intercepted arc, so
a = 0.5 × 136 = 68

Janice already has $65 dollars in her savings account. If she puts $5 per week in her account, write an equation to find out how many weeks she must save to have at least $200 in her account.
2 points
Your answer
Answer: 65 + 5x ≥200
Step-by-step explanation:
Hi, to answer this question we have to write an inequality with the information given:
Janice's savings (65) plus the product of the amount she saves per week (5) and the number of weeks (x) must be higher or equal to $200.
Mathematically speaking:
65 + 5x ≥200
If we solve it for x:
5x ≥200-65
5x ≥135
x ≥ 135/5
x ≥ 27 weeks

a) 108°
Answer:
b) 54°
Step-by-step explanation:
a) By arc sum property of a circle.
[tex] m\widehat {AEB} + m\widehat {AB} = 360°\\
252° + m\widehat {AB} = 360°\\
m\widehat {AB} = 360°- 252°\\
\huge \red {\boxed {m\widehat {AB} = 108°}} \\[/tex]
b) In the given figure, DC is tangent to the circle with O at point A and AB is chord or secant. Therefore, by tangent secant theorem:
[tex] m\angle BAC = \frac{1}{2} \times m\widehat {AB}\\\\
\therefore m\angle BAC = \frac{1}{2} \times 108°\\\\
\huge \purple {\boxed {m\angle BAC = 54°}} [/tex]

The point-slope form of the line is [tex]y-19=2(x-5)[/tex].
Important information:
A line passes through the two points [tex](5,19)[/tex] and [tex](-5,-1)[/tex].Use the first point in the equation.We need to find the point-slope equation for the line
Point-slope equation:The point-slope form of a line that passes though the points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is:

Mel's Furniture received an invoice dated September 27 for 5 bedroom sets at $3,000 each. The invoice indicated a chain discount of 5/8/3. The seller of the furniture prepaid the freight of $200 (FOB Shipping Point). Terms were 2/10, EOM. Assuming that Mel pays within the discount period, what is the total payment amount?
Answer: $12,916.70
Step-by-step explanation:
Given the following:
Invoice received :
Bedroom set = 5
Cost per set = $3,000
Chain discount = 5/8/3
Freight cost = $200
If Mel pays within the discount period:
Chain discount given = 5/8/3
Therefore, net equivalent price rate equals:
(1 - 0.05) × (1 - 0.08) × (1 - 0.03) =
0.95 × 0.92 × 0.97 = 0.84778
Net price = total cost × 0.84778
($3000 × 5) × 0.84778
$15000 × 0.84778 = $12,716.7
Net equivalent price + FOB Shipping
$12,716.7 + $200 = $12,916.70
Two Parallel lines are cut by a transversal and form a pair of alternate exterior angles. One angle measures (6x+5) and other measures (7x+4). Explain how to determine what those other angles actually measure.
Answer:
The other angles will measure 83.9° and 96.1°Step-by-step explanation:
If two parallel lines are cut by a transversal and form a pair of alternate exterior angles, then the sum of the two exterior angles will be equal to 180° as shown;
If one angle measures (6x+5) and other measures (7x+4), then;
(6x+5)+(7x+4) = 180° (sum of two exterior angles)
Firstly, lets get the value of x from the equation.
6x+7x+9 = 180°
13x= 180-9
13x = 171
x = 171/13
x = 13.15°
The first angle 6x+5 will measure 6(13.15)+5 = 83.9°
The other angle 7x+4 will mesure 7(13.15)+4 = 96.1°
Answer:
Since the lines are parallel, the alternate exterior angles are congruent. Therefore you can set the expressions equal to each other and solve for x. Then you can substitute the value of x back into either expression to find the angle measure.

which set of angles has the same terminal arm as 70 degrees?
Answer: B = B ∈ {70° + n*360° I n ∈ Z } where Z is the set of the integer numbers.
Step-by-step explanation:
If we have an angle A, the other angles that have the same terminal arm than A can be written as:
B = A + n*360°
Here B is a "coterminal" angle to A. (they have the same terminal side)
where n can be any integer number (if n = 0 we have A = B, which is trivial, this means that any angle can be coterminal with itself.)
So we can write the set as:
B = B ∈ {70° + n*360° I n ∈ Z }
The set of angles that has the same terminal arm as 70 degrees is B = B ∈ {70° + n*360°, n ∈ Z}.
We have to determine, which set of angles has the same terminal arm as 70 degrees.
According to the question,
Let, The angle A and other angle B that have the same terminal arm as A can be written as,
B = A + n × 360°
Where the value of angle A is 70 degrees.
B is the coterminal angle, and they have the same terminal,
And n is the number of integers.
Substitute the value of A in the equation,
B = 70 + n × 360°
Two angles are coterminal if they are drawn in the standard position and both have their terminal sides in the same location.
Since the value of n is equal to 0 then A = B,
Therefore, The angles coterminal with itself is called trivial.
Hence, The set of angles that has the same terminal arm as 70 degrees is B = B ∈ {70° + n*360°, n ∈ Z}.

What is the diagonal length of the window?
O A) 2 ft
O C 8 ft
O B) 5 ft.
O D) 12 ft.
The solution for this problem is:
To get the diagonal length of a square, multiply the length of one side by the square root of 2:If the length of one side is x.
length of diagonal = x √2
length of a diagonal = 4√2
length of a diagonal = 5.6569 feet
Use the Pythagorean theorem
Diagonal = sqrt(4^2 + 3^2)
Diagonal = sqrt( 16 + 9)
Diagonal = sqrt(25)

A circular flower bed is 15 m in diameter and has a circular sidewalk around it that is 3 m wide. Find the area of the sidewalk in square meters. Use 3.14 for pi π.
Answer:
346.19 m²
Step-by-step explanation:
The diameter of the circular flower bed is 15 m and the length of the sidewalk round the flower bed is 3 m.
This means that an extra length of 3 m is added on each side.
The joint diameter of the flower bed and sidewalk is:
15 + 3 + 3 = 21 m
The radius is half of the diameter, that is 10.5 m
The area of the sidewalk is therefore:
A = pi * r²
Where r = radius
A = 3.14 * 10.5²
A = 346.19 m²

Match each function with its domain. 1. S(x) = √x 2. H(x) = √2+x 3. Z(x) = √x-2 4. Q(x) = √2-x 5. V(x) = √-x 6. N(x) = ^3√2-x x ≤ 2 x ≥ -2 x ≥ 0 x ≥ 2 x ≤ 0 All real numbers
Answer:
1. x ≥ 0
2. x ≥ -2
3. x ≥ 2
4. x ≤ 2
5. x ≤ 0
6. All real numbers
Step-by-step explanation:
Domain of square function:
Suppose we have a square function in the following format:
[tex]f(x) = \sqrt[n]{g(x)}[/tex]
If n is even, the domain of f(x) is:
[tex]g(x) \geq 0[/tex]
Otherwise, if n is odd, the domain of f(x) is all real numbers.
1. S(x) = √x
If n does not appear is that it is 2.
g(x) = x
So the domain is:
[tex]x \geq 0[/tex]
2. H(x) = √2+x
g(x) = 2 + x
So
[tex]2 + x \geq 0[/tex]
[tex]x \geq -2[/tex]
3. Z(x) = √x-2
g(x) = x - 2
[tex]x - 2 \geq 0[/tex]
[tex]x \geq 2[/tex]
4. Q(x) = √2-x
g(x) = 2 - x
[tex]2 - x \geq 0[/tex]
[tex]-x \geq -2[/tex]
Multiplying by -1, everything
[tex]x \leq 2[/tex]
5. V(x) = √-x
g(x) = -x
Then
[tex]-x \geq 0[/tex]
Multiplying by -1
[tex]x \leq 0[/tex]
6. N(x) = ^3√2-x
Cubic root(odd number), so all real numbers.
