At a local basketball game, t-shirts are shot out of a cannon with an initial velocity of 44 feet per second and from an initial height of 15 feet. While seated, you catch the t-shirt in your lap that is 3 feet from the floor. After how many seconds did the t-shirt land in your lap?

Answer:

-6

Step-by-step explanation:

According to question,

x + 8 = 2(x + 7)

x + 8 = 2x + 14

2x - x = 8 - 14

x = -6

A number is increased by 8 which is equal to twice of the same number increase by 7 then the number will be -6.

Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations.

A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.

As per the statement given in the question,

Let the number is x.

Number is increased by 8,

x + 8

Also,

Equal to twice of same number increased by 7.

Then the expression will be,

x + 8 = 2(x + 7)

x + 8 = 2x + 14

x = -6

Answer:

Our juices’ journey to your table starts on the thousands of acres of citrus farms dotting Western North America. The process begins when the fruit is harvested at its sweetest, then sent to our plant to be pressed and bottled. From the plant, our juice is sent to retailers throughout the West, including Ralph’s, Bristol Farms and Pavilions to name a few. This lateral integration gets the freshest, best tasting juices to our customers as quickly as possible, and makes Perricone Farms a true “Farm-Bottle-Table” company. You’ll taste the difference with every sip.

Answer:

y = 5.6

Step-by-step explanation:

Use Sine

Sine = [tex]\frac{opposite}{hypothenuse}[/tex]

Sine 45 = [tex]\frac{y}{18}[/tex]

Sine of 18 is 0.309

0.309 = [tex]\frac{y}{18}[/tex]

Multiply 18 on both sides

0.309 x 18 = [tex]\frac{y}{18}[/tex] x 18

Answer:

140 + 250 = 390

Step-by-step explanation:

I think 390

Formula is:

L x W

7 x 20 = 140

30 - 20 = 10 x 25 = 250

so therefore add the the two areas of the two shapes to get 390 feet squared.

The boat is x=376 foot away from the light house.

A person is watching a boat from the top of a lighthouse. The angle of depression from the person to the boat is 28°. The lighthouse is 200 feet tall.

Trigonometry is defined as the study of angles.

Let the boat is x distance away from the lighthouse

assume a right-angle triangle ABC with AB =perpendicular=200, BC = base=X,  Angle CAB = 28°(angle of depression means the angle from the boat to the top of lighthouse is also 28°)

tan28 = 200/X
X = 200/tan28
X = 376 foots

Thus, The boat is x=376 foot away from the lighthouse.

Answer:

The 1st option

Step-by-step explanation:

Because x can be anything that's not imaginary and y has to be below 2 always because of the negative value added before the 3. Also it's impossible to reverse the sign of the negative because negative x would only result in 3 becoming a fraction.

Answer:

  acute

Step-by-step explanation:

I like to think of this in terms of the "form factor" (a term I made up). It is computed as ...

  f = a² +b² -c²

where a, b, c are the side lengths, and c is the longest.

The interpretation is ...

  f > 0 . . . acute

  f = 0 . . . right

  f < 0 . . . obtuse

Here, we have ...

  f = 13² +17² -21² = 17 . . . . . the triangle is acute

_____

Additional comment

The measure of the largest angle is ...

  arccos(f/(2ab)) = (17/(2(13·17)) = arccos(1/26) ≈ 87.8°

You can see that (2ab) is always positive, so the sign of f matches the sign of the cosine of the angle. That is what leads to the above interpretation.

This formula comes from the Law of Cosines, of which the Pythagorean theorem is a special case.

We know that the standard form of the equation is:

ax + by = c

and we are given the equation:

y = -3x + 6

Converting to standard form:

3x + y = 6                                  [adding 3x on both sides]

3x + y = 6

Answer:

19 seconds.

Step-by-step explanation:

Given that the clock was exactly on time at 7am, and at 1pm the clock was 228 seconds late, to determine, at that rate, how slow was the clock half an hour, the following calculation must be performed:

1 PM = 13:00

13 - 7 = 6

228/6 = 38

38/2 = 19

Thus, every half hour the clock is delayed 19 seconds.

Answer:

The dolphin is five feet in the air after about 0.22 and 1.40 seconds.

Step-by-step explanation:

The height h (in feet) of the dolphin as it jumped out of the water after t seconds is given by the function:

[tex]h(t)=-16t^2+26t[/tex]

We want to determine the time(s) when the dolphin is five feet in the air.

Since the dolphin is five feet in the air, h(t) = 5:

[tex]5=-16t^2+26t[/tex]

Solve for t. Rearrange:

[tex]16t^2-26t+5=0[/tex]

We can use the quadratic formula, given by:

[tex]\displaystyle t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

In this case, a = 16, b = -26, and c = 5.

Substitute:

[tex]\displaystyle t=\frac{-(-26)\pm\sqrt{(-26)^2-4(16)(5)}}{2(16)}[/tex]

Evaluate:

[tex]\displaystyle t=\frac{26\pm\sqrt{356}}{32}[/tex]

Simplify the square root:

[tex]\sqrt{356}=\sqrt{2\cdot 2\cdot 89}=2\sqrt{89}[/tex]

Hence:

[tex]\displaystyle t=\frac{26\pm2\sqrt{89}}{32}[/tex]

Simplify:

[tex]\displaystyle t=\frac{13\pm\sqrt{89}}{16}[/tex]

Hence, our solutions are:

[tex]\displaystyle t=\frac{13-\sqrt{89}}{16}\approx 0.22\text{ and } t=\frac{13+\sqrt{89}}{16}\approx1.40[/tex]

The dolphin is five feet in the air after about 0.22 and 1.40 seconds.
