A projectile is fired upward from the ground with an initial velocity of 300 feet per second. Neglecting air resistance, the height of the projectile at any time t can be described by the polynomial function P(t) = ­16t 2 + 300t

Answers

Answer 1

Answer: The polynomial that describes the projectile's height is:

P(t) = - ­16t*2 + 300t

For t = 1 second we have:

P(1) = - 16*1^2 + 300*1

P(1) = 284 ft

The height of the projectile after 1 second is 284 feet.

Step-by-step explanation:

Answer 2

The height should be 284 feet.

Given that,

A projectile is fired upward from the ground with an initial velocity of 300 feet per second Neglecting air resistance, the height of the projectile at any time t can be described by the polynomial function P(t) = ­[tex]16t \times 2 + 300t[/tex]

Based on the above information, the calculation is as follows:

[tex]P(t) = -16t\times 2 + 300t[/tex]

Here t = 1  

[tex]P(1) = - 16\times 1^2 + 300\times 1[/tex]

= 284 ft

Megan has a large packing box shaped as a cube with a volume of 216 cubic feet.

What is the side length for the cubical box? Explain how you find the length.
PLZZ help

Answers

Answer:

s = 6 feet

Step-by-step explanation:

Given that,

The volume of the cube, V = 216 feet³

We need to find the side length for the cubical box. We know that the volume of the cube is given by :

[tex]V=s^3[/tex], s is the side length of the box.

So,

[tex]s={V}^{1/3}\\\\s={216}^{1/3}\\\\s=6\ feet[/tex]

So, the side length for the cubical box is equal to 6 feet.

The square pyramid shown below has a base with sides of 10 units. The slant height of the pyramid is 8 units. What is the vertical height, h?

Answers

Make a right triangle by using half the base and using the Pythagorean theorem calculate the height.

Height = sqrt(8^2 - 5^2)

Height = sqrt(64 - 25)

Height = sqrt(39)

Height = 6.245 ( Round the answer as needed).

Answer:

6.2

Step-by-step explanation:

We can use the Pythagorean Theorem to find h.

The equation for the Pythagorean Theorem is a^2+b^2=c^2

We see that the hypotenuse of the right triangle is 8. One leg is h. The other leg is 5 , which is half the length of the base.

We have:

a^2+b^2=c^2

5^2+h^2=8^2

25+h^2=64

h^2=39

h= square root of 39

h = 6.244

Xuan sold 9 used books for $9.80 each. With the
money from these sales, she bought 4 new books and
had $37.80 left over. What was the average amount
Xuan paid for each new book?
A. $ 5.60
B. $ 9.45
C. $10.08
D. $12.60
E. $22.05

Answers

Answer:

I think the answer is A, $5.60

Step-by-step explanation:

9.80 x 9= 88.20

88.20 - 37.80 = 50.40

5.60 x 9 = 50.40

The average amount paid for the books is $12.60

Since Xuan sold 9 used books for $9.80 each, the total amount that's paid for the books will be:

= $9.80 × 9

= $88.20

Since she bought 4 new books and had $37.80 left over, the cost of the books will be

= $88.20 - $37.80

= $50.40

Since she bought 4 books, the average amount paid for the books will be:

= $50.40/4

= $12.60

Therefore, the correct option is D

Find the equation of a line that passes through the point (-2,4) and has a gradient of -3.
Leave your answer in the form
y

m
x

c

Answers

Equation of a line is y = mx +c

m is the gradient, which is given as -3 so now you have:

y = -3x + c

Replace y and x with the given point and solve for c:

4 = -3(-2) + c

Simplify:

4 = 6 + c

Subtract 6 from both sides:

c = -2

The equation becomes:

y = -3x-2

In the last year, U.S. car sales of all makes and models have dropped by 16%. Let's say that a car dealer sells 325 cars. If this number drops by 16%, how many cars will the dealer sell then? Round to the nearest whole number.
A 203 cars
B 309 cars
C 273 cars
D 256 cars

Answers

Answer:

c. 273 cars

Step-by-step explanation:

First you need to find what 16% of 325 is

325x.16=52

because the number sold dropped by 16% you will subtract 52 from 325

325-52=273

you can also calculate the answer by subtracting 100% by 16%

100%-16%=84%

now you can calculate 84% of 325

325x.84=273

In parallelogram ABCD, the measure of angle A is 99°. What are the measures of the other 3 angles? Explain how you know.

Answers

Answer:

B:81

C:99

D:81

Step-by-step explanation:

In a parallelogram, opposite angles are congruent and consecutive angles (angles next to each other) are supplementary, or add to 180. Considering that there is no diagram, we can use our imagination here. So B is next to A, so <A+<B=180. <B must equal 81. I repeated this process for the rest of the angle measures.

<A=99

[tex]\\ \sf\longmapsto <A=<C=99°[/tex]

sum of corresponding angles is 180°

[tex]\\ \sf\longmapsto <A+<B=180[/tex]

[tex]\\ \sf\longmapsto 99+<B=180[/tex]

[tex]\\ \sf\longmapsto <B=180-99[/tex]

[tex]\\ \sf\longmapsto <B=81[/tex]

[tex]\\ \sf\longmapsto <B=<D=81°[/tex]

A manufacturer knows that their items have a normally distributed lifespan, with a mean of 8.8 years, and standard deviation of 2.2 years.

If 5 items are picked at random, 5% of the time their mean life will be less than how many years?

Answers

First of all we need o use the standard normal table to see what value if z will have 10% of the area (probability) to the left of it. We see that z value is approximately z = -1.282

Now all we have to do is calculate the value of x that corresponds to this value of z. We have

( x - µ ) / σ = -1.282 Substituting in the known values, we have

( x - 4.4 ) / 1.3 = -1.282 and x = 2.73 years

HURRRRRYYYYYRick read the following argument:Although the gas helium is the second most abundant element in the known universe, its supplies on Earth are limited. Most helium comes either from mining minerals or as a byproduct of natural gas. Although helium is in low supply, the demand for it is quite high. It can be used for a variety of medical purposes, including the treatment of breathing problems such as asthma. Helium also has heart and nerve protective properties, and doctors are beginning to use it in surgery. Yet current laws make recycling helium unprofitable. For the sake of our health, those laws must change.Which statement would be the most appropriate in a conclusion to this argument? Why? A. These laws are unlikely to change, so we must take steps to manufacture helium on our own. This statement makes the logical leap that if we can't recycle helium, we should create it. B. Until human disease is a thing of the past, we cannot support laws that put helium supplies at risk. This restates the claim of this argument, which is that we should do everything in our power to treat human diseases. C. If there is any practical use for helium other than medicine, laws should change to protect current supplies of the gas. This sentence summarizes one of the major points of the argument, which is that helium reserves are in low supply. D. Human health depends on helium, and therefore it is necessary to change the laws that make it hard to acquire.
