Answer:
Answer is the explanation!
Step-by-step explanation:
We know that x is the amount of seconds after the ball is dropped from the cliff and h is the height after that many x seconds.
So h(x) will represent the height of the ball after x seconds.
Meaning h(3) will reprensent the height after x seconds of being drooped.
We can simply replace x with 3 to find the height of it being dropped after 3 seconds.
Hoped this helped,
JoeLouis2
Answer:
Step-by-step explanation:
h(3) = -16(3)^2 + 200 = 56 (feet). This is the height of the ball 3 seconds after having been dropped from a cliff, as measured upward from ground level.

Answer:
B
Step-by-step explanation:
Start by using the distance formula to find the raidus
The two points are (-2,1) and (-4,1)
√((-4+2)²+(1-1)²)= 2
The radius is two and we have our center which means we can write
(x+2)²+(y-1)²=4
now it's just a matter of expanding everyhting
x²+4x+4+y²-2y-3=0
x²+y²+4x-2y+1=0
This is equal to B
p(x) = 4x^2 - 15x - 25

A newsletter publisher believes that less than 49% of their readers own a laptop. For marketing purposes, a potential advertiser wants to confirm this claim. After performing a test at the 0.10 level of significance, the advertiser decides to reject the null hypothesis. What is the conclusion regarding the publisher's claim
Answer:
The answer is "At the 0,10 level, there should be enough proof that the percentage is below 49%"
Step-by-step explanation:
Null and alternative hypothesis:
[tex]H_0 :P \geq 0.49\\\\H_1:P<0.49 \ \ (\text{Left tailed test})\\\\[/tex]
Significance level: [tex]\alpha = 0.10[/tex]
It is decided that the null hypothesis at the defined meaning level is rejected.

Given right triangle ABC with altitude BD drawn to hypotenuse AC. If AB=20 and AD=10, what is the length of AC?
Answer:
mAC = 40
Step-by-step explanation:
Use similar triangles,
BAC and DAB are similar
therefore
CA/AB = BA/AD
CA/20 = 20/10
cross multiply
AC = CA = 20*20/10 = 40
Or use metric relations
CA*AD = BA^2
CA = BA^2/AD = 20^2/10 = 40

The mean weight of a domestic house cat is 8.9 pounds with a standard deviation of 1.1 pounds. The distribution of domestic house cat weights can reasonably be approximated by a normal distribution. What proportion of domestic house cats weigh less than 7 pounds?
Answer:
0.0421
Step-by-step explanation:
We solve using the z score formula
z-score is is z = (x-μ)/σ,
where x is the raw score
μ is the population mean = μ = 8.9 pounds
σ is the population standard deviation = σ = 1.1 pounds
For x < 7 pounds
z = 7 - 8.9/1.1
= -1.72727
Probability value from Z-Table:
P(x<7) = 0.042059
Therefore, the proportion of domestic house cats weigh less than 7 pounds is
0.042059
Approximately = 0.0421

Answer:
73,205 vinyls
Step-by-step explanation:
To calculate the number of vinyls sold we need to calculate the compounded increase. To do this we simply raise the number of times that the initial value increases by the number of difference in years from the start to the current year. Then we multiply this number by the initial number of vinyl records. Since there are 4 years between 2012 and 2016, the formula would be the following...
50,000 * [tex]1.1^{4}[/tex] = x
50,000 * 1.4641 = x
73,205 = x
Finally, we can see that there will be a total of 73,205 vinyls in 2016

Answer:
279 feet
Step-by-step explanation:
To find x, we solve using the Trigonometric function of Tangent
tan θ = Opposite/ Adjacent
θ = 64°
Length of the shadow = Adjacent = 136 feet
Height of the building = Opposite = h
Hence,
tan 64 = h/136 feet
Cross Multiply
h = tan 64 × 136 feet
h = 278.84132245 feet
Approximately, h to the nearest foot ≈ 279 feet
Therefore, the height of the building = 279 feet

Round your answer to one decimal digit. The volume of a cylinder is 1 800 cm3. If the height of the cylinder is 40 cm then the diameter of the cylinder is
Answer:
7.57 cm
Step-by-step explanation:
Volume of a cylinder = πr²h
π = 3.14
r= radius
h = height
1,800 = 3.14 x r² x 40
r² = 1800 /(3.14 x 40)
r² = 14.33121
√14.33121 = r
r = 3.785658 cm
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
Diameter = 2 x 3.785658 cm = 7.57cm
Do the data in the table represent a direct variation or an inverse variation? Write an equation to model the data in the table.
x= 1 2 5 10
y= 6 12 30 60
a. direct variation y=1/6x
b. inverse variation xy=6
c. direct variation y=6x
d. inverse variation xy=1/6
c. y=6x direct variation
Answer:
the table represent a direct variation
Step-by-step explanation:
as when x=1
y=2
and
x=10
y=60
Answer:
y = 6x direct variation
Step-by-step explanation:
Remember that direct variation is y = kx and inverse variation is y = k/x where k is a constant
x= 1 2 5 10
y= 6 12 30 60
First look at direct y = kx solving for k y/x =k
y/x from the table is 6/1 =6 12/2 = 6 30/5 =6 60/10 =6 so k=6
This is a direct variation with k=6
y = 6x
Given sin e
; and angle 0 is in Quadrant III, what is the exact value of cos 0 in
simplest form? Simplify all radicals if needed.
Answer:
[tex]\cos \theta = -\frac{\sqrt{5}}{3}[/tex]
Step-by-step explanation:
Draw a right triangle with angle [tex]\theta[/tex]. In all right triangles, the sine of an angle is equal to its opposite side divide by the hypotenuse of the triangle. Therefore, label the side opposite to [tex]\theta[/tex] as 2 and the hypotenuse (longest side) of the right triangle as 3.
To find the last side, use the Pythagorean Theorem:
[tex]a^2+b^2=c^2[/tex], where [tex]c[/tex] is the hypotenuse of the triangle.
Solving for [tex]a[/tex]:
[tex]a^2+2^2=3^2,\\a^2+4=9,\\a^2=5,\\a=\pm\sqrt{5}\implies \sqrt{5}[/tex]
In all right triangles, the cosine of an angle is equal to its adjacent side divided by the hypotenuse. However, the cosine of all angles in Quadrant III are negative. Therefore, the desired answer is [tex]\cos \theta=\boxed{-\frac{\sqrt{5}}{3}}[/tex].
Verify:
[tex]\sin \theta =-\frac{2}{3},\\\\\theta=\arcsin(-\frac{2}{3}}),\\\\\cos(\arcsin(-\frac{2}{3}}))=-\frac{\sqrt{5}}{3}\checkmark[/tex]

Dylan opened a credit card account with $575.00 of available credit. Now that he has made some purchases, Dylan's account only has $408.25 of available credit. What is the percentage decrease of the amount of available credit in Dylan's account?
Answer:
Dylan's credit card account has decreased by 29%.
Step-by-step explanation:
You first have to subtract:
$575.00 - $408.25 = $166.75.
You then have to divide the amount decreased by the total amount.
$166.75 / $575.00 = 0.29 = 29%
29% is the amount decreased in the credit card account.
