FIRST CORRECT ANSWER GETS BRAINLIEST!!!!!!!! Suppose you were digging at a rate of 10 feet per day. Assume you are ar sea level when you begin digging. If there are 365 days in a year, write an equation to represent the depth of the hole where d= depth in feet and t= time in years
Answer:
simple
Step-by-step explanation:
365 x 10 = 3650 feet
took you 1 year
and adding on sea level 1,312 feet

sin(180)cos(50)-sin(50)cos(180)
0*cos(50)-sin(50)*-1
0+sin(50)

What is the sum of 7 of the interior angles of a regular decagon?
Answer:
The answer is 1008 degrees
Step-by-step explanation:
The sum of 7 of the interior angles of a regular decagon is 1008°.
What is interior angle of polygon?It is an angle inside a shape. All the interior angles in a regular polygon are equal.Formula to find the sum of interior angles of a polygon:S = (n - 2) × 180°, where n is the number of sides of the regular polygon.
What is decagon?"It is a polygon having ten sides, ten interior angles and ten vertices."
For given example,
We need to find the sum of 7 of the interior angles of a regular decagon.
Number of sides of decagon (n) = 10
Using the formula of sum of interior angles,
⇒ S = (n - 2) × 180°
⇒ S = (10 - 2) × 180°
⇒ S = 1440°
This means the sum of all interior angles of a regular decagon is 1440°.
We know, there are 10 interior angles of regular decagon.
Let 'x' represents the measure of each interior angle of a regular decagon.
⇒ 10x = 1440°
⇒ x = 1440/10
⇒ x = 144°
This means, the interior angle of a regular decagon measures 144°
So, the sum of 7 of the interior angles would be,
7 × 144° = 1008°
Therefore, the sum of 7 of the interior angles of a regular decagon is 1008°.

Question 7 of 8
Calculate the amount of interest earned on a $7,500 investment made for 2 years at
5.5% p.a..
Answer:
$825
Step-by-step explanation:
Formula we use:
I = Prt
Given:
P = 7500
r = 5.5% or 0.055
t = 2
Work:
I = Prt
I = 7500(0.055)(2)
I = 412.5(2)
I = 825
Which function shows the function f(x) = 3^x being
translated 5 units to the left?
A. f(x) = 3^x – 5
B. f(x) = 3^(x+5)
C. f(x) = 3^(x - 5)
D. f(x) = 3^x + 5
Answer:
B.
Step-by-step explanation:
When you want to move a function on a graph from left to right, you "move" the x, and when moving the x; it's the opposite. So, C would move the function 5 units to the right because it is subtracting.
The correct option will be f(x) = 3^(x - 5)
What is translation?A translation is a transformation that moves every point in a figure the same distance in the same direction.
Given that, the function f(x) = 3ˣ, being translated 5 units to the left.
Since, the function is being translated in left, therefore, we subtract 5 from x,
i.e. f(x) = 3⁽ˣ⁻⁵⁾
Hence, f(x) = 3⁽ˣ⁻⁵⁾ is the function shows the function f(x) = 3ˣ being
translated 5 units to the left.

There are two spinners containing only white and green slices. Spinner A has 4 white slices and 1 green slice. All the slices are the same size. Spinner B has 3 white slices and 9 green slices. All the slices are the same size. Each spinner is spun. List these events from least likely to most likely. Event : Spinner B lands on a green slice. Event : Spinner A lands on a white or green slice. Event : Spinner A lands on a white slice. Event : Spinner B lands on a yellow slice.
Answer:
Step-by-step explanation:
Ok, lets list the important things
only green and white slicesall slices same sizespinner A has 4/5 white slices and 1/5 green slicesspinner B has 3/12 white slices and 9/12 green slicesThe 4 options are:
spinner B lands on a green slicespinner A lands on a white or green slicespinner A lands on a white slicespinner B lands on a yellow sliceWe already know that choice 2 is 100% probable and option 4 is 0% probability, because in option 2, the spinner A ONLY has white or green slices so the spinner must land on the slice. In option 4, no matter which spinner is spun no yellow slices are available to land on.
the chance of option 1 happening is 9/12 which is 3/4 which is 75%
the chance of option 3 of happening 4/5 which is 80%
option 1 has a 75% chance
option 2 has a 100% chance
option 3 has an 80% chance
option 4 has a 0% chance
this means that the order is:
1. option 4
2. option 3
3. option 1
4. option 2
because it is least likely to most likely.

Step-by-step explanation:
The state education commission wants to estimate the fraction of tenth grade students that have reading skills at or below the eighth grade level. In an earlier study, the population proportion was estimated to be 0.19. How large a sample would be required in order to estimate the fraction of tenth graders reading at or below the eighth grade level at the 98% confidence level with an error of at most 0.02
Answer:
A sample of 2084 is needed.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In an earlier study, the population proportion was estimated to be 0.19.
This means that [tex]\pi = 0.19[/tex]
98% confidence level
So [tex]\alpha = 0.02[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.02}{2} = 0.99[/tex], so [tex]Z = 2.327[/tex].
How large a sample would be required in order to estimate the fraction of tenth graders reading at or below the eighth grade level at the 98% confidence level with an error of at most 0.02?
This is n for which M = 0.02. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.02 = 2.327\sqrt{\frac{0.19*0.81}{n}}[/tex]
[tex]0.02\sqrt{n} = 2.327\sqrt{0.19*0.81}[/tex]
[tex]\sqrt{n} = \frac{2.327\sqrt{0.19*0.81}}{0.02}[/tex]
[tex](\sqrt{n})^2 = (\frac{2.327\sqrt{0.19*0.81}}{0.02})^2[/tex]
[tex]n = 2083.4[/tex]
Rounding up:
A sample of 2084 is needed.

Answer:
choice 1) 0, -4/5
Step-by-step explanation:
1/(t² + t) = 1/t - 5
multiply both sides of the equation by (t² + t):
1 = (t² + t)/t - 5t² - 5t
1 = t + 1 - 5t² -5t
-5t² - 4t = 0
t(-5t - 4) = 0
t = 0
-5t = 4
divide both sides by -5:
t = -4/5

Figure A ~ Figure B
Find the volume of Figure A
9514 1404 393
Answer:
1 m³
Step-by-step explanation:
The ratio of volumes is the cube of the ratio of corresponding linear dimensions.
Va/Vb = ((2 m)/(8 m))³ = (1/4)³ = 1/64
Va = Vb(1/64) = (64 cu. m)/(64) = 1 cu. m
