A thermometer falls from a weather
balloon at a height of 7,744 ft. If the
equation for height as a function of time
is h(t) = -16t2 + initial height wheret is
time in seconds and h(t) is height in feet,
how many seconds will it take for the
thermometer to hit the ground?
[?] seconds
Answer:
It will take 22 seconds for the thermometer to hit the ground.
Step-by-step explanation:
A thermometer falls from a weather balloon at a height of 7,744 ft.
This means that the initial height is of 7744ft.
h(t) = -16t2 + initial height
So
[tex]h(t) = -16t^2 + 7744[/tex]
How many seconds will it take for the thermometer to hit the ground?
This is t for which [tex]h(t) = 0[/tex]. So
[tex]0 = -16t^2 + 7744[/tex]
[tex]16t^2 = 0 + 7744[/tex]
[tex]t^2 = \frac{7744}{16}[/tex]
[tex]t = \sqrt{\frac{7744}{16}}[/tex]
[tex]t = 22[/tex]
It will take 22 seconds for the thermometer to hit the ground.

The circumference of a circle is 7π in. Find its radius, in inches.
Answer:
3.5 in
Step-by-step explanation:
Circumference = 2π(radius)
7π = 2π (radius)
7π/2π = radius
Pi in numerator and denominator cancel each other.
7/2 = radius
3.2 in = radius
Answer:
[tex] \bf \huge \: 11 \: inches.[/tex]
Step-by-step explanation:
Given :The circumference of a circle is 7π in.to find :Find its radius, in inches.formula used :r = c/2where,
r = radius c = circumference explanation :⟼ r = c/2
⟼ r = 7×22÷7/2 in
⟼ r = 22/2 in
⟼ r = 11 in.
Hence, radius is 11 inches.On a map, 9 cm represents 15 miles. If the distance between two cities on the map is 15 cm, how many miles separate the cities?
Answer:
15 cm on the map is equal to 25 miles.
Step-by-step explanation:
Given that,
On a map, 9 cm represents 15 miles.
The distance between two cities is 15 cm. We need to find the distance in miles.
9 cm = 15 miles
[tex]1\ cm=\dfrac{15}{9}\ \miles[/tex]
So, 15 cm is equal to,
[tex]15\ cm=\dfrac{15}{9}\times 15\ miles\\\\=25\ miles[/tex]
So, 15 cm on the map is equal to 25 miles.

Round to the nearest tenth.
Answer:
1103.1 is the answer
Step-by-step explanation:
Identify the statements below as sometimes true, always true, or never true.
a. –4<59
b. X< 1
c. -5> -2
d. 3x + 5 = 2
e. 61 = 61
f. -6 < -6
Answer:
Sometimes true: b. d.
Always true: a. e.
Never True: c. f.
Step-by-step explanation:
b. and d. depend on what value you put in, so that is sometimes true. Now a. and e. are always true because it is correct. C. and f. are never true because the equation does not make any sense.

Given that the two triangles below are similar , find the values of g and h
Answer:
g = 4
h = 4.5
Step-by-step explanation:
The corresponding sides of two similar figures are proportional to each other.
Therefore,
[tex] \frac{g}{3} = \frac{8}{6} = \frac{6}{h} [/tex]
✔️Find g:
[tex] \frac{g}{3} = \frac{8}{6} [/tex]
Cross multiply
g*6 = 8*3
6g = 24
Divide both sides by 6
g = 24/6
g = 4
✔️Find h:
[tex] \frac{8}{6} = \frac{6}{h} [/tex]
Cross multiply
8*h = 6*6
8h = 36
h = 36/8
h = 4.5
How many terms are in this expression? 5+4⋅6

How many triangles can be constructed with side lengths of 9.6 cm, 11.6 cm, and 21.2 cm?
0
1
more than one
NEED DIS ANSWER NOW PLZZZ
Answer: A) 0 triangles
============================================================
Explanation:
Adding up the two smaller sides gets us 9.6+11.6 = 21.2, but this result is not larger than the third side of 21.2
For a triangle to be possible, we need to be able to add any two sides and have the sum be larger than the third remaining side. This is the triangle inequality theorem.
I recommend you cutting out slips of paper with these side lengths and trying it out yourself. You'll find that a triangle cannot be formed. The 9.6 cm and the 11.6 cm sides will combine to form a straight line that is 21.2 cm, but a triangle won't form.
As another example of a triangle that can't be formed is a triangle with sides of 3 cm, 5 cm, and 8 cm. The 3 and 5 cm sides add to 3+5 = 8 cm, but this does not exceed the third side. The best we can do is form a straight line but that's not a triangle.
In short, zero triangles can be formed with the given side lengths of 9.6 cm, 11.6 cm, and 21.2 cm

Question 15 2 points)
The PERIMETER of the rectangle shown is 236 inches. Find the value of x given the dimensions of the rectangle belove.
The method of tree ring dating gave the following years A.D. for an archaeological excavation site. Assume that the population of x values has an approximately normal distribution
1229 1257 1243 1194 1268 1316 1275 1317 1275
(a) Use a calculator with mean and standard deviation keys to find the sample mean year x and sample standard deviation s. (Round your answers to the nearest whole number.)
(b) Find a 90% confidence interval for the mean of all tree ring dates from this archaeological site. (Round your answers to the nearest whole number.)
Answer:
A) Mean = 1264
Standard deviation = 37
B) CI ≈ (1241, 1287)
Step-by-step explanation:
A) Mean = Σx/n
Σx = 1229 + 1257 + 1243 + 1194 + 1268 + 1316 + 1275 + 1317 + 1275
Σx = 11374
Mean(x¯) = 11374/9
Mean(x¯) ≈ 1264
Standard deviation = √(∑(x - x¯)²/(n)
From online calculator;
Standard deviation; s ≈ 37
B) Our distribution factor is; DF = n - 1 = 9 - 1 = 8
From t-table attached, our critical value at 90% Confidence interval is t = 1.86
Formula for confidence interval is;
CI = x¯ ± t(s/√n)
CI = 1264 ± 1.86(37/√9)
CI = 1264 ± 22.94
CI ≈ (1241, 1287)
Katie needs 3/4 cup of sugar to make cookies. She only has 1/3 cup. How much more sugar does Katie need?
Answer:
[tex]\frac{5}{12}[/tex] cups
Step-by-step explanation:
This question is asking for the difference between the two values so subtraction is necessary
[tex]\frac{3}{4} -\frac{1}{3}[/tex]
Multiply the top and bottom of the first fraction by 3 and the second one by 4[tex]\frac{3*3}{4*3} -\frac{1*4}{3*4} = \frac{9}{12} -\frac{4}{12}[/tex]
Now just substract
9 - 4 = 5 ==> [tex]\frac{9}{12} -\frac{4}{12} = \frac{5}{12}[/tex]
