Slove It!!! I need help!
Answer:
6 should be the correct answer!
Step-by-step explanation:
all of the work I did, you can ignore these:
1 x 2 = 2
2 x 2 = 4
2 x (2 - 1) = 2 x 1 = 2
2 + 4 = 6
Answer:
The answer is 6
Step-by-step explanation:
What value of x satisfies this equation?
10(1.5)^(3x) = 80
Round your answer to the nearest hundredth.
Answer:
X = 1.71
or
X = 1.70951
Step-by-step explanation:
Good Luck!
The required value of x for the given equation is approximately 1.71.
What are exponential functions?When the expression of function is such that it involves the input to be present as exponent (power) of some constant, then such function is called exponential function. There usual form is specified below. They are written in several such equivalent forms.
Equation:
The given equation is [tex]10(1.5)^{3x} = 80[/tex]
Divide both sides by 10.
[tex](1.5)^{3x} = \dfrac{80}{10}\\\\(1.5)^{3x} = 8[/tex]
Taking log on both sides, we get
[tex]log (1.5)^{3x} = log 8\\\\3x log (1.5) = log 8[/tex]
Divide both sides by 3log(1.5).
x = log 8/ 3log(1.5)
x = 1.71
Therefore, the required value of x for the given equation is approximately 1.71.

Find the equation of a line that passes through (5.3) and (4,5).
Answer:
y=-2x+13
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(5-3)/(4-5)
m=2/-1
m=-2
y-y1=m(x-x1)
y-3=-2(x-5)
y=-2x+10+3
y=-2x+13
1. An object is blasted upward at an initial velocity of 320 ft/s. The height, h(t), of the object is a function of time, t (in seconds), and is given by the formula h(t) = -16t2 + 320t. How long will it take the object the hit the ground after takeoff?
Answer:
20 seconds
Step-by-step explanation:
roots are (0,0) and (20,0) so 20-0 will provide the time from takeoff to landing
Solve the right triangle. Round decimal answers to the nearest tenth.
PLS PLSS HELPPPP 25 POINTSSS
Answer:
Step-by-step explanation:
[tex]14^2 = b^2+6^2\\b^2 = 14^2-6^2\\b = \sqrt{14^2-6^2} \\ = \sqrt{160}\\ = 12.6491106407[/tex]
Rounding off to nearest tenth:
b ≈ 12.6
tanθ = 6/12.6
[tex]tan^{-1} (6/12.6)\\ = 25.46334506\\[/tex]
Hence angle A ≈ 25.5
Angle B = 180-25.5-90
Angle B = 64.53665494
Hence, Angle B ≈ 64.5

3(5 p - 1 p ) - 4 ( 3 p -7) when p = 4
Answer:
=28
Step-by-step explanation:
3(5 p - 1 p ) - 4 ( 3 p -7) when p = 4
3 (20-4) -4 ( 12 - 7)
60 - 12 -48 +28
= 28
3 ( 5p - p ) - 4 ( 3p - 7 ) =
3 ( 4p ) - 12p + 28 =
12p - 12p + 28 =
0 + 28 = 28
Thus the value of p is not importent at all and the answer is always 28 .
The following equation:
P= 111t + 3400
gives the total population, P, of a small city t years after 1994. Use the equation to determine when
(what year) the population reached a population of 4288 people.
Answer: The population reached a total of 4288 people in the year 80.72
Hint: Don't forget that you are being asked for a year for your answer, not the variables.
Answer:
all I know is p = 3511

Which is a perfect square?
Answer:
I believe it's 6^2.
Step-by-step explanation: 6^2 is the same as 6 times 6. Here's a tip, if you see a 2 as an exponent, you can also say x squared. X to the power of 2 is the same as x squared.
Answer:
[tex]6^{2}[/tex]
Step-by-step explanation:
[tex]6^{1}[/tex] = 6 [tex]\sqrt{6}[/tex] = 2.45 (NOT a perfect square)
[tex]6^{2}[/tex] = 36 [tex]\sqrt{36}[/tex] = 6 (perfect square)
[tex]6^{3}[/tex] = 216 [tex]\sqrt{216}[/tex] = 14.7 (NOT a perfect square)
[tex]6^{5}[/tex] = 7776 [tex]\sqrt{7776}[/tex] = 88.18 (NOT a perfect square)
If the answer ends with a decimal, they are not perfect squares.
Consider the following equation. Graph 5x + 6y = 30
PLEASE SHOW STEPS
Answer:
Step-by-step explanation:
Convert the equation into slope-intercept form.
5x-6y =30 Subtract 5x from each side
-6y = -5x + 30 Multiply each term by -1
6y = 5x – 30 Divide each side by 6
y = ⅚x - 5
2. Create a table of different x and y values,
x ⅚x – 5 y
-12 ⅚(-12) – 5 -15
-6 ⅚(-6) – 5 -10
0 ⅚(0) – 5 -5
6 ⅚(6) – 5 0
12 ⅚(12) – 5 5
3. Convert the table to ordered pairs
(-12,-15)
(-6, -10)
(0, -5)
(6, 0)
(12, -5)
4. Plot the points and draw a line through them.
please help 75 points
Answer:
The median for the first plot is 3
The median for the second plot is 7
The largest value for the first plot is 6
So the difference for the first plot is 6 - 3 = 3
The largest value for the second plot is 10
So the difference for the second plot is 10 - 7 = 3
This means the variation quadrial is bigger for the red plot, but the difference beetween the points is equal.
Answer:
not 75 points

Answer:
21 feet²
Step-by-step explanation:
To find the area of a composite figure, we can break the shape into pieces and solve for the area separately.
There are multiple ways to separate the figure, but for this explanation we will break it into two rectangles, 5×3 and 3×2.
The area of a rectangle can be found by multiplying the length and width of the shape. So for the left rectangle, we will multiply 5 by 3.
5 · 3 = 15
The area of our first rectangle is 15 ft².
Next, we will find the area of the right rectangle, by multiplying 3 by 2.
3 · 2 = 6
The area of the second rectangle is 6 ft².
Now we can add the areas, 15 and 6, together to find the total area.
15 + 6 = 21
The area of the figure is 21 ft².
I hope this helps ^^ Good luck ∩_∩
NEED HELP! What is the value of x?
Step-by-step explanation:
from the triangle
let angle close to 130⁰ be y
130⁰+y⁰=180⁰(sum of angles on a straight line)
y⁰= 180⁰-130⁰
y = 50⁰
70 + y + x = 180⁰(sum of angles in a triangle)
70 + 50 + x= 180⁰
x= 180⁰-120⁰
x=60⁰

It is known that the amount of time needed to change the oil on a car is normally distributed with a standard deviation of 5 minutes. The amount of time to complete a random sample of 10 oil changes was recorded and listed here. Compute the 99% confidence interval estimate of the mean of the population.
11 10 16 15 18 12 25 20 18 24
Answer:
(11.605 ; 22.195)
Step-by-step explanation:
11 10 16 15 18 12 25 20 18 24
Sample mean, xbar = Σx / n = 169 / 10 = 16.9
Standard deviation = 5.152 ( using calculator)
Confidence interval :
Xbar ± Margin of error
Margin of Error = Tcritical * s/√n
Df = n - 1 = 10 - 1 = 9
Tcritical at 99%, df =9 = 3.2498
Margin of Error = 3.2498 * 5.152/√10 = 5.2946
Lower boundary :
16.9 - 5.2946 = 11.6054
Upper boundary :
16.9 + 5.2946 = 22.1946
(11.605 ; 22.195)

A digital camera usually costs $700. This week it is on sale at a discount of 20%. What
is the sale price of the digital camera?
Answer:
560
Step-by-step explanation:
So we know that 20% goes into 100% 5 times.
700/5 will give you a clean 140, meaning 20% of the price is 140
Thus 700-140 and you get 560 dollars
If you have a calc you could also do 700 x .80 (since .80 is also equal to 80%) and get the same answer
