Answer:
x will be equivalent to 24
Step-by-step explanation:
apply the multiplication rule to the exponents in (a^4)^6
4 times 6= 24, so (a^4)^6 is equivalent to a^24
What angle maximizes the area of the triangle below?
Answer:
90°
Step-by-step explanation:
Area of triangle with sides a and b and included angle Θ:
A = (1/2)ab * sin Θ
dA/dx = (1/2)ab cos Θ
(1/2)ab cos Θ = 0
cos Θ = 0
Θ = 90°

Ms. Wall will roll two number cubes. What is
the probability that she will roll a sum of 9 ?
Express your answer as a fraction.
(I'll give brainlist if u get it right)
Answer: 9/1
Step-by-step explanation: Apologies for the mistake. Let's calculate the probability again.
To find the probability of rolling a sum of 9 on two number cubes, we need to determine the number of favorable outcomes and divide it by the total number of possible outcomes.
For a sum of 9, the following combinations are favorable:
(3, 6), (4, 5), (5, 4), (6, 3)
So, there are 4 favorable outcomes.
The total number of possible outcomes is still 6 × 6 = 36.
The probability of rolling a sum of 9 is:
Probability = Number of favorable outcomes / Total number of possible outcomes
Probability = 4 / 36
Simplifying the fraction, we get:
Probability = 1 / 9
Therefore, the probability of rolling a sum of 9 is 1/9, not 11/18 as previously stated.
Ms. Sandoval walked 2 miles a
day for 5 days. If she did this for
8 weeks, what was the total
amount of miles she walked?
Answer:
Step-by-step explanation:
since 5 has nothing to do with this question lets put the 5 aside and focus with the 2 miles and the 8 weeks.. if there is 7 days in a week and there is 8 weeks that is 56 days in total.. multiply by 2 miles per day would equal...

Find the slope of the line passing through the points (6,6) and (6, -7).
slope: 1
Answer:
The line is a vertical line, which does not have a slope.
Step-by-step explanation:
Slope of a line:
Suppose we are given two points in the format (x,y) of a line. The slope is given by the change in y divided by the change in x.
(6,6) and (6, -7).
Change in y: -7 - 6 = -13
Change in x: 6 - 6 = 0
Slope is a division by 0, which means that the line is a vertical line, which does not have a slope.

Answer:
[tex]C' = (2,8)[/tex]
[tex]A' = (4,4)[/tex]
[tex]T' = (10,10)[/tex]
Step-by-step explanation:
Given
[tex]k =2[/tex]
[tex]C =(1,4)[/tex]
[tex]A = (2,2)[/tex]
[tex]T =(5,5)[/tex]
Solving (a): The new points
To do this, we simply multiply the old points by the scale factor.
i.e.
[tex]New = Old * k[/tex]
So:
[tex]C' = (1,4) * 2 = (2,8)[/tex]
[tex]A' = (2,2) * 2 = (4,4)[/tex]
[tex]T' = (5,5) * 2 = (10,10)[/tex]

Given that v = (5,-4,4) and w = (9,-2,7) evaluate v • w.
A. 81
B. 19
C. (45,8,28)
D. (-40,-16,-8)
Answer:
81
Step-by-step explanation:
Evaluating v • w
Recall: Given vectors a and B in Cartesian plane, x, y and z
vector a = [ax ay az] and b = [bx by bz]
The dot product is :
a•b = axbx + ayby + azbz
Using the relation above,
v • w = (5*9) + (-4*-2) + (4*7)
v • w = 45 + 8 + 28
v • w = 81
Hence, v • w = 81

Answer:
Can't be Solved
Step-by-step explanation:
tan x = opp/adj
tan x = 23/11
tan x = 2.09090909 which is about
tan x = 2.09
x = 64.4 degrees which is the tangent of 2.09 in degrees.
x = 64.4 degrees

cube root 1331 : reciprocal of 0.2
give your answer in the form n:1
Answer:
2.2 : 1
Step-by-step explanation:
cube root 1331 : reciprocal of 0.2
give your answer in the form n:1
The cube root of 1331
(1331)^1/3 = 11
Reciprocal of 0.2 = 1 /0.2 = 5
Hence, the ratio Can be expressed as :
11 : 5
In the form n : 1
divide both sides by 5
11/5 : 5 /5
2.2 : 1
Find the surface area of the cone.Use 3.14 for pi and round your answer to the nearest hundredth
Answer:
145.0 cm^2
Step-by-step explanation:
Given data
r= 4cm
l= 5cm
h=??
Apply Pythagoras theorem to find h we have
h^2= 4^2+5^2
h^2= 16+25
h^2= 41
h=√41
h= 6.4cm
Substitute into the formula for the surface area of cone
A=πr(r+√h^2+r^2)
A=3.14*4(4+√6.4^2+4^2)
A=12.56(4+√40.96+16)
A=12.56(4+√56.96)
A=12.56(4+7.547)
A=12.56*11.547
A=145.0 cm^2

Step-by-step explanation:
Use the graph to answer the question.
On a coordinate plane, a line goes from (negative 5, 7) to (3, 3).
Which parametric equations describe the curve?
x = –t + 1 and y = 0.5t + 4 when –2 ≤ t ≤ 6
x = –t + 1 and y = 0.5t + 4 when –5 ≤ t ≤ 3
x = 0.5t + 4 and y = –t + 1 when –2 ≤ t ≤ 6
x = 0.5t + 4 and y = –t + 1 when –5 ≤ t ≤ 3
The answer for this question is A:
A = x = –t + 1 and y = 0.5t + 4 when –2 ≤ t ≤ 6
The parametric equations of the curve are:
x = –t + 1 and y = 0.5t + 4 when –5 ≤ t ≤ 3
Parametric equation of the line:The parametric equation of the line is, [tex]x=x_0+at,y=y_0+bt[/tex] where [tex](x_0,y_0)[/tex] is the point on the line and [tex]\frac{b}{a}[/tex] is the slope of the line with a, b are real numbers.
Slope of the line:If (a, b) and (c, d) are any two points on the line then, slope of the line is:
m = (d - b)/(c - a)
For given situation,
a line goes from (-5, 7) to (3, 3).
Using the formula of slope, the value of m i.e., slope of the line would be,
⇒ m = (7 - 3)/(-5 - 3)
⇒ m = 4/(-8)
⇒ m = 1/(-2)
⇒ m= 0.5/(-1)
Comparing with m = b/a,
b = 0.5 and a = -1.
From the graph of the line given below,
A point (1, 4) is also on the line.
Let [tex]\bold{(x_0,y_0)=(1,4)}[/tex]
Using the parametric equation of the line,
[tex]x=x_0+at[/tex]
⇒ x = 1 + (-1)t
⇒ x = -t + 1
and [tex]y = y_0+bt[/tex]
⇒ y = 4 + (0.5)t
⇒ y = 0.5t + 4
Therefore, the parametric equations of the curve are:
x = –t + 1 and y = 0.5t + 4 when –5 ≤ t ≤ 3
