Step-by-step explanation:
Since this is a right triangle and we are given an angle measure that measure 45, the other angle measure also measure 45.
So this means we are dealing with a 45-45-90 triangle.
A 45-45-90 triangle legs are equal to each other and the hypotenuse measures sqr root of 2 times more than the legs.
The hypotenuse measure 2 times sqr root of 14 so divide by sqr root of 2 to find x and y.
[tex] \frac{2 \sqrt{14} }{1} \times \frac{1}{ \sqrt{2 } } = \frac{ \sqrt{56} }{ \sqrt{2} } = \sqrt{28} = 2 \sqrt{7} [/tex]
Since x and y are equal, they both measure
[tex]2 \sqrt{7} [/tex]

Which statements about her claim are true? Check all that apply. Six of the one-half cubes would have a volume of 3 cubic units. Nine of the one-third cubes would have a volume of 6 cubic units. Since One-half and One-third do not have common factors, stacks of one-half cubes and stacks of third-cubes could never have the same volume. Three of the one-third cubes will make 1 unit cube. Two of the one-half cubes will make 1 unit cube. Both stacks will have a volume of 3 cubic units.

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
Answers
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 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.)
Answers
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)

Answers
Answer:
9
Step-by-step explanation:
UT^2 = UV * UW
6^2 = (x - 7)(x - 7 + 5)
36 = (x - 7)(x - 2)
36 = x^2 - 2x - 7x + 14
x^2 - 9x - 22 = 0
(x - 11)(x + 2) = 0
x - 11 = 0 or x + 2 = 0
x = 11
UW = x - 7 + 5
UW = 11 - 7 + 5
UW = 9

bought the shares for a total of $480.75
so you’re going to multiply $3.75 by 120 shares since that’s how much they cost each and that gives you $450 cost so then you subtract the $480.75 from $450.00 which is the cost of the shares and that gives you $30.75 in total

Given that the two triangles below are similar , find the values of g and h
Answers
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
