Answer:
Step-by-step explanation:
h(t) = 841 - 16t
[Is this written correctly? The time is usually t^2, not t. I'll solve with the written equation, but check the equation]
The height at ground level is 0, so we want the value of t when h(t) = 0:
0 = 841 - 16t
-16t = -841
t = 53 seconds
One can also graph this formula and find the time to hit the ground at the point the line intersects the x axis (x = 0).
====
If the equation should have read h(t) = 841 - 16t^2, solve it as above, setting h(t) = 0.
t = (29/4) seconds
This can also be graphed.

Answer:
106
Step-by-step explanation:
The given is a pentagon and the sum of interior angles is = 540
so to find the value of x:
132 + 90 + x + x + x = 540 add like terms
222 + 3x = 540 subtract 222 from both sides
3x = 318 divide both sides by 3
x = 106
Fully describe the association that would exist between variables with the given correlation coefficient. (a) r=0.6578 (b) r= 0.1648 (c) r = -0.9875
Answer:
Step-by-step explanation:
Correlation is a statistical technique that is used to measure and describe a relationship between two variables. Usually the two variables are simply observed, not manipulated. The correlation requires two scores from the same individuals. These scores are normally identified as X and Y.

Find a common denominator and then subtract and simplify your answer.
11/12-3/4
a: 1/7
b: 1/5
c: 1/6
Answer: c. 1/6
Step-by-step explanation:
The least common demoninator would be 12, as 12 is a multiple of 4.
We can multiply the fraction 3/4 by (3/3)
3/4 = 3/4*(3/3)
= (3*3)/3*4)
= 9/12
We can plug in the value of 9/12 in as 3/4 back into the expression:
= 11/12 - 9/12
We can combine the numerators since there is a common denominator:
= (11-9)/12
= 2/12
Divide the numerator and denominator of this fraction by 2:
= 1/6

Given a polynomial function f(x) = 2x2 – 3x + 5 and an exponential function g(x) = 2% – 5, what key features do f(x) and g(x) have in common?
A. Both f(x) and g(x) have the same domain of (0, -60).
B. Both f(x) and g(x) have the same range of [0,-).
C. Both f(x) and g(x) have the same x-intercept of (2,0).
D. Both f(x) and g(x) increase over the interval of (-4,-).
A. Both [tex]f(x)[/tex] and [tex]g(x)[/tex] have the same domain of [tex](9, +\infty)[/tex].
How to analyze similarities in two functions
In this question we must analyze the domain, range, x-intercepts and increase intervals:
Domain[tex]Dom \{f(x)\} = \mathbb{R}[/tex]
[tex]Dom \{g(x)\} = \mathbb{R}[/tex]
Both functions are continuous.
Range[tex]Ran \left\{f(x)\right\} = (3.875, +\infty)[/tex]
[tex]Ran \{g(x)\} = (-5, +\infty)[/tex]
x-Intercepts[tex]f(x):[/tex] [tex](x,y) = \emptyset[/tex]
[tex]g(x):[/tex] [tex](x,y) = (2.322, 0)[/tex]
Increase intervals[tex]f(x):[/tex] According to the graph, [tex]f(x)[/tex] increase over the interval of [tex](3.875, + \infty)[/tex].
[tex]g(x) :[/tex] According to the graph, [tex]g(x)[/tex] increase over the interval of [tex]\mathbb{R}[/tex]
After a quick analysis, we conclude that option A offer the best approximation to characteristics of both functions. [tex]\blacksquare[/tex]
RemarkThe statement presents mistakes and is poorly formatted. Correct form is:
Given a polynomial function [tex]f(x) = 2\cdot x^{2}-3\cdot x + 5[/tex] and an exponential function [tex]g(x) = 2^{x}-5[/tex]. What key features do [tex]f(x)[/tex] and [tex]g(x)[/tex] have in common?
A. Both [tex]f(x)[/tex] and [tex]g(x)[/tex] have the same domain of [tex](9, +\infty)[/tex].
B. Both [tex]f(x)[/tex] and [tex]g(x)[/tex] have the same range of [tex](-\infty, 0][/tex].
C. Both [tex]f(x)[/tex] and [tex]g(x)[/tex] have the same x-intercept of [tex](2,0)[/tex].
D. Both [tex]f(x)[/tex] and [tex]g(x)[/tex] increase over the interval of [tex](-4, +\infty)[/tex].

Select the correct answer. The perimeter of a triangle is 30 units. If it’s is dilated with respect to origin by a scale factor of 0.5, what is the perimeter of the resulting triangle?
Answer: 15
Step-by-step explanation:
We know that the scale factor of the dilation is the ratio of similtude, and that the ratio of similitude is equal to the ratio of the perimeters. So, the new perimeter is 30(0.5)=15.
A circle is drawn on the coordinate plane. It
has a center at (2, 1) and passes through the
point (2, 5). What is the approximate
circumference of the circle?
Step-by-step explanation:
please mark me as brainlist please
Answer:
Using Pythagorean theorem we can find the radius which is the distance between the center and any point along the circle:
r=((5-1)^2+(2-2)^2)^(1/2)
r=(4^2-0^2)^(1/2)
r=4 units.
Circumference=2pr so our circumference is 8p units^2
so about 25.13 u^2

Help plss it's due today??...!
Answer:
The answer is 80°
Step-by-step explanation:
Given;We are given a hexagon with 6 anglesTo Find;The value of xHere, we know that the sum of all interior angles of hexagon is equal to 720°
So,
x + x + 140 + 140 + 140 + 140 = 720
2x + 560 = 720
2x + 560 – 560 = 720 – 560
2x = 160
2x/2 = 160/2
x = 80°
Thus, The value of x is 80°
For Verification
x + x + 140 + 140 + 140 + 140 = 720
80 + 80 + 140 + 140 + 140 + 140 = 720
720 = 720
L.H.S = R.H.S
Hence Verified!

The sum of the digits of a two-digit number is 7. If the digits are reverses, the new number is 9 more than the original number. Find the original number.

Step-by-step explanation
Let the ones's digit =x.
So, sum of the digits =7
Tens's digit =7−x
Original no. =10(7−x)+x=70−10x+x=70−9x
Reversed no. =10x+7−x=9x+7
2(orig no) = reversed no. −2
2(70−9x)=9x+7−2
140−18x=9x+5
27x=135
x=5
Ten's digit =7−5=2
