Answer:
1.71
Step-by-step explanation:
got it right on my test
The required value of x for the given equation is about 1.71.
Equation:Important information:
The given equation is [tex]10(1.5)^{3x}=80[/tex].Divide both sides by 10.
[tex](1.5)^{3x}=\dfrac{80}{10}[/tex]
[tex](1.5)^{3x}=8[/tex]
Taking log on both sides, we get
[tex]\log (1.5)^{3x}=\log 2^3[/tex]
[tex]3x\log (1.5)=3\log 2[/tex]
Divide both sides by 3log(1.5).
[tex]x=\dfrac{3\log 2}{3\log 1.5}[/tex]
[tex]x=\dfrac{\log 2}{\log 1.5}[/tex]
[tex]x\approx 1.71[/tex]
Therefore, the required value of x for the given equation is about 1.71.

A union b intersection c’
See the attached image.
We start this problem by finding the union of [tex]A[/tex] and [tex]B[/tex]. This is highlighted in green in the attachment.
Next, we find the intersection of that area and [tex]C[/tex] (highlighted in yellow). This means we need to find the area where both [tex]A\cup B[/tex] and [tex]C[/tex] are highlighted. This intersection is highlighted in pink and is the final answer.

All of the following ordered pairs satisfy the function rule y=-3x+2 except
(1, -1)
(4,-10)
(-2,8)
(-3, 12)
Answer:
The ordered pair (-3, 12) DOES NOT satisfy the equation.
Step-by-step explanation:
Given the function
[tex]y=-3x+2[/tex]
Let us substitute all the values to check which points satisfy the function.
FOR (1, -1)
y = -3x+2
substitute x = 1, y = -1
-1 = -3(1) + 2
-1 = -3+2
-1 = -1
TRUE!
Thus, the ordered pair (1, -1) satisfies the equation.
FOR (4, -10)
y = -3x+2
substitute x = 4, y = -10
-10 = -3(4) + 2
-10 = -12+2
-10 = -10
TRUE!
Thus, the ordered pair (4, -10) satisfies the equation.
FOR (-2, 8)
y = -3x+2
substitute x = -2, y = 8
8 = -3(-2) + 2
8 = 6 + 2
8 = 8
TRUE!
Thus, the ordered pair (-2, 8) satisfies the equation.
FOR (-3, 12)
y = -3x+2
substitute x = -3, y = 12
12 = -3(-3) + 2
12 = 9+2
12 = 11
L.H.S ≠ R.H.S
FALSE!
Thus, the ordered pair (-3, 12) DOES NOT satisfy the equation.
Therefore, the ordered pair (-3, 12) DOES NOT satisfy the equation.

A room 24'-0" x 22'-6" requires ____ square feet of ceiling tile and ____ square yards of carpet. (1 square yard = 9 square feet; 3' x 3' = 9')
Answer:
540 ft² ; 60 yd²
Step-by-step explanation:
1 square yard = 9 ft²
Dimension of room:
24ft 0in by 22ft 6in
1 in = 1/12 ft
6in = (1/12) * 6 ft = 0.5 feet
Hence, Dimension of room in feet ;
24ft by 22.5 ft ;
Square feet of ceiling tiles; (24 * 22.5)ft² = 540ft²
Square yards of carpet needed :
1 yd² = 9 ft²
Let yd² of carpet needed = x
1 yd² = 9 ft²
x yd² = 540 ft²
Cross multiply ;
9x = 540
x = 540 / 9
x = 60
Hence, 60yd² of carpet is needed

Step-by-step explanation:
For the given pair of equations, give the slopes of the lines, and then determine whether the two lines are parallel, perpendicular, or neither.
10x – 3y = 3
3x + 10y = 30
Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
O A. The slope of 10x - 3y = 3 is
(Type an integer or a simplified fraction.)
O B. The slope of 10x - 3y = 3 is undefined.
Answer:
the lines are perpendicular to each other
Step-by-step explanation:
The standard form of equation of a line is y = mx+c
m is the slope of the line
c is the intercept
Given the equations
10x – 3y = 3
3x + 10y = 30
Get the individual slopes
For 10x – 3y = 3
Rewrite in standard form
-3y = -10x + 3
y = 10/3 x - 3/3
y = 10/3 x - 1
Slope of the line is 10/3
For the equation 3x + 10y = 30
10y = -3x+30
y = -3/10 x + 3
Slope of the line is -3/10
Take the product of the slopes
10/3 * -3/10 = -1
Since the product of their slopes is -1, hence the lines are perpendicular to each other
The physical plant at the main campus of a large state university receives daily requests to replace florescent light bulbs. The distribution of the number of daily requests is bell-shaped and has a mean of 37 and a standard deviation of 8. Using the empirical (68-95-99.7) rule, what is the approximate percentage of light bulb replacement requests numbering between 37 and 61
Answer:
49.85% of light bulb replacement requests numbering between 37 and 61
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 37, Standard deviation = 8
Using the empirical (68-95-99.7) rule, what is the approximate percentage of light bulb replacement requests numbering between 37 and 61
37 is the mean
61 = 37 + 3*8, so 61 is three standard deviations above the mean
The normal distribution is symmetric, which means that 50% of the measures are above the mean and 50% are below.
By the Empirical Rule, of the 50% of the measures that are above the mean, 99.7% will be between the mean of 37 and three standard deviations above the mean, which is 61. So, this percentage is:
0.5*0.997 = 0.4985 = 49.85%

What is the slope of (-2,5) and (-2, -6)
a m=undintified
b m= 0
c m= 11 over 4
d m= negative 11 over 4
Answer:
B
Step-by-step explanation:
Apply slope intercept form, y2-y1 / x2 - x1. -6 is y2, -2 is x2, 5 is y1, and -2 is x1.
-6 - 5 / - 2 - (-2)
-11 / -2 + 2
-11 / 0
0
The slope is 0. B is your answer. I hope this helps you!

The question is on the jpg link.
Answer:
A. y=-4/3x
Step-by-step explanation:
The line that passes through those points has a slope of -4/3
Slope intercept form is y=mx+b
whereas m is the slope and b is where the line intercepts the y-axis.
the line intercepts the y-axis at the origin.
Substitute the slope into the equation
y=-4/3x+0
y=-4/3x
