A barometer falls from a weather balloon
at a height of 14,400 ft. If the equation
for height as a function of time is
h(t) = -16t2 + initial height where t is time
in seconds and h(t) is height in feet, how
many seconds will it take for the
barometer to hit the ground?
Answer:
Step-by-step explanation:
h(t) = -16t² + 14400
0= -16t² + 14400
(1/-16)×-14400=-16t²(1/-16)
900=t²
[tex]\sqrt{900} =\sqrt{t^{2}}[/tex]
30=t
Hence, the time taken in seconds for barometer to hit the ground is 30.
A barometer falls from a weather balloon from a height of 14400, this means that the initial height is 14,400 ft.
How many seconds will it take for the barometer to hit the ground?
The initial height of a barometer is 14,400 ft.
After the barometer falls from a weather balloon it hits the ground and final height is 0.
So, the equation h(t)= -16[tex]t^{2}[/tex]+ initial height
putting h(t)=0 which is the final height and initial height=14,400 we get,
0=-16[tex]t^{2}[/tex] +14,400
16[tex]t^{2}[/tex]=14,400
t=[tex]\sqrt{14,400/16}[/tex]
[tex]t^{2}[/tex]=900
t=[tex]\sqrt{900}[/tex]
t=30
Hence, the time taken by barometer to hit the ground is 30 seconds.

A local Hamburger shop sold a combined total of 553 hamburgers and cheeseburgers on Saturday. They were 53 more cheeseburgers sold and hamburgers. How many hamburgers were sold on Sunday?
Answer:
250 hamburgers were sold on Sunday
Step-by-step explanation:
Let there are x hamburgers and y cheeseburgers sold on Sunday.
ATQ,
x + y = 553 .....(1)
There were 53 more cheeseburgers sold than hamburgers.
y = 53 + x ....(2)
Put the value of y from equation (2) in equation (1).
x + (53 + x) = 553
2x+53 = 553
2x = 500
x = 250
Put the value of x in equation (2).
y = 53 + 250
y = 303
Hence, 250 hamburgers were sold on Sunday

Answer:
f(x) = 2,000(0.94)^x; 952 km^2
Step-by-step explanation:
Formula for exponential growth or decay:
f(x) = P(1 + r)^x
where
f(x) = future value in year x
P = present value
r = annual rate of growth (positive) or decrease (negative)
x = time in years
In this problem,
P = 2,000
r = -6% = -0.06; here r is negative since this is a decreasing function
The formula is
f(x) = 2,000(1 - 0.06)^x
f(x) = 2,000(0.94)^x
For year 12, x = 12.
f(x) = 2,000(0.94)^x
f(12) = 2,000(0.94)^12
f(12) = 952

The area, A, of a triangle is 15.3 square centimeters. Its base, b, is
4.5 centimeters. The formula for finding the area of a triangle
is A = 1/2bh. Write and solve an equation to find the height, h, of the
triangle.
The height (h) of the triangle whose area is 15.3 sq. cm with a base of 4.5 cm is: 6.8 cm.
Recall:
Area of triangle = ½×b×h, where h = height and b = base.Given the following:
Area of triangle = 15.3 sq. cmBase (b) = 4.5 cmTo solve an equation to find the h, plug n the given values into A = ½×b×h
15.3 = ½ × 4.5 × h
Multiply both sides by 22(15.3) = 4.5(h)
30.6 = 4.5h
Divide both sides by 4.530.6/4.5 = h
h = 6.8 cm

Answer:
[tex] \frac{2}{5}x = \frac{7}{20}x + \frac{1}{4} [/tex]
[tex] -\frac{3}{4} = -\frac{1}{20}x - \frac{1}{2} [/tex]
Step-by-step explanation:
Given,
[tex] -\frac{3}{4} + \frac{2}{5}x = \frac{7}{20}x - \frac{1}{2} [/tex]
There are two possible ways to start solving for the value of x.
✔️The first is, add both sides by ¾
[tex] -\frac{3}{4} + \frac{2}{5}x + \frac{3}{4} = \frac{7}{20}x - \frac{1}{2} + \frac{3}{4} [/tex]
[tex] \frac{2}{5}x = \frac{7}{20}x + \frac{1}{4} [/tex] (-½ + ¾ = ¼)
This equation represents the first possible way to begin with.
✔️The second is subtract both sides by ⅖x
[tex] -\frac{3}{4} + \frac{2}{5}x - \frac{2}{5}x = \frac{7}{20}x - \frac{1}{2} - \frac{2}{5} [/tex]
[tex] -\frac{3}{4} = \frac{7}{20}x - \frac{2}{5}x - \frac{1}{2} [/tex]
[tex] -\frac{3}{4} = \frac{7 - 8}{20}x - \frac{1}{2} [/tex]
[tex] -\frac{3}{4} = -\frac{1}{20}x - \frac{1}{2} [/tex]
This equation represents another way to start.

If x is greater than 0, what is the difference of 6x√14x - 5√56x^3 in simplest radical form?
Answer:
6x√14x - 5√56x^3 = -4√14x√x
I hope this helps at least. :)
Simply put, expressing a radical in its lowest extreme form implies simplifying it and that there are no more squared roots, cube roots, 4th roots, and so on to find. This also entails eliminating any radical from a fraction's base, and further calculation can be defined as follows:
Given:

Explain why the graph below might be misleading.
Comparison of Funds Money Earned Fund A Fund B Fund C Fund D
a. The graph is not misleading.
b. The horizontal axis has intervals that are not comparable.
c. The bars are in different colors, so it skews the information,
d. The graph has no scale, so it's impossible to compare the money earned.
Answer:
d. The graph has no scale, so it's impossible to compare the money earned.
Step-by-step explanation:
The graph is misleading because it has "no scale" in response to the money earned. It would actually be hard to plot them on the graph without the scale. If you look at the graph, you won't be able to compare how much funds Fund C made in comparison to Fund A, B and D. You won't be able to tell the actual gap in the money they've earned. The data above is not clearly illustrated in this case.
