Find the value of (1/5)⁻² + (1/2)⁻³ + (1/4)⁻¹
Answer:
Answer = 37
Step-by-step explanation:
= (5)² + (2)³ + (4)¹
= 25 + 8 + 4
= 37 Answer
Answer: The answer is 37
Step-by-step explanation:
Step 1: Use Negative Power Rule: x^-a=1/x^a. So 1/(1/5)^2+(1/2)^-3+(1/4)^-1
Step 2: Use Division Distributive Property: (x/y)^a=x^a/y^a. So 1/1/5^2+(1/2)^-3+(1/4)^-1
Step 3: Simplify 5^2 to 25. So 1/1/25+(1/2)^-3+(1/4)^-1
Step 4: Use Negative Power Rule: x^-a=1/x^a. So 1/1/25+1/(1/2)^3+(1/4)^-1
Step 5: Use Division Distributive Property: (x/y)^a=x^a/y^a. So 1/1/25+1/1/2^3+(1/4)^-1
Step 6: Simplify 2^3 to 8. So 1/1/25+1/1/8+(1/4)^-1
Step 7: Use Negative Power Rule: x^-a=1/x^a. So 1/1/25+1/1/8+1/1/4
Step 8: Invert and multiply. 25+1/1/8+1/1/4
Step 9: Invert and multiply. 25+8+1/1/4
Step 10: Invert and multiply. 25+8+4
Step 11: Simplify 25+8 to 33. So 33+4
Step 12: Simplify. So the answer is 37

If each of the numbers in the following data set were multiplied by 18, what would be the new median of the data set? 14, 20, 18, 58, 71, 36
A. 504
B. 360
C. 324
D. 648
Answer:
504
step by step : 14x18=252. 20x18=360. 18x18=324. 58x18=1044. 71x18= 1278. 36x18=648. 28x18=504.
Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.

What is the magnitude and direction of the PQ with tail and head points P(-6, 0) and Q(2, 4)?
8.9 units, 63.4° north of east
8.9 units, 26.6° north of east
13.4 units, 180° west
13.4 units, 0° east
Answer:
What is the magnitude and direction of the PQ−→− with tail and head points P(-6, 0) and Q(2, 4)? magnitude = √(64+16) = √80 = appr 8.9 , ruling out c.
hope this helps
The magnitude of PQ is 8.9 and PQ is making an angle of 26.57° so 8.9 units, 26.6° north of east will be the correct answer.
What is a vector?A vector is a quantity in which direction and magnitude both matters called a vector.
A vector joining by two points (x₁,y₁) and (x₂,y₂) will be (x₂-x₁)[tex]\hat{i}[/tex] + (y₂-y₁)[tex]\hat{j}[/tex]
The magnitude of this vector will be
[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
The direction of this vector will be
[tex]\\tan^{-1}(\frac{y_2-y_1}{x_2-x_1)}[/tex]
Given P(-6,0) and Q(2,4) so vector joining by
[tex]\vec{PQ}[/tex] = [2-(-6)][tex]\vec{i}[/tex] + [4-0][tex]\vec{j}[/tex]
[tex]\vec{PQ}[/tex] = 8[tex]\vec{i}[/tex] + 4[tex]\vec{j}[/tex]
now, the magnitude [tex]\vec{PQ}[/tex] will be
⇒ [tex]\sqrt{(8^2+4^2)}[/tex]
⇒ 8.944
The direction of the vector [tex]\vec{PQ}[/tex] will be
⇒ [tex]\tan^{-1}(\frac{4}{8})[/tex]
⇒26.57°
So, the magnitude of PQ is around 8.944 and the direction is 26.57° from the positive x axis so it's north of the east.

Answer:
32
63
Step-by-step explanation:
m<BCA=180-148-32 Subtract 180-148 b/c x<BCA is along the straight line ACD. A straight line will have an angle of 180 degrees.
m<CAB=180-32-85=63 All triangles have angles which add up to 180 degrees. Subtract 32 and 85 from 180 to get 63.
Step-by-step explanation:
148 + x = 180
x = 180 - 148
x = 32
Find m<CAB basically means find the measure of the angle of A ( m<A )
m<B + m<A + x = 180
85 + m<A + 32 = 180
117 + m<A = 180
m<A = 180 - 117
m< A = 63, so m<CAB = 63
And m<BCA means find the measure of angle C(m<C) or as we did it earlier as x, which is the same thing.
So m<BCA = 32

Factor the following polynomial completely. -0.8x2 - 6.4x + 7.2
Answer:
-0.8(x + 9)(x - 1)
Step-by-step explanation:
Note that 0.8 is a factor of the three coefficients -0.8, -6.4 and 7.2. Thus,
-0.8x2 - 6.4x + 7.2 = 0.8(-1x^2 - 8x + 9), or, equivalently,
= -0.8(x^2 + 8x - 9), which factors further as follows:
= -0.8(x + 9)(x - 1)

Step-by-step explanation:
Angle A and angle B are complementary. Angle A has a
measure of (2X + 16). Angle B has a measure of 40. What is
the value of x?
Answer:
x = 17
Step-by-step explanation:
Angle A and angle B are complementary.
Therefore,
(2x + 16)° + 40° = 90°
(2x + 16)° = 90° - 40°
(2x + 16)° = 50°
2x + 16 = 50
2x = 50 - 16
2x = 34
x = 34/2
x = 17
