Answer 1

Answer:

IJ = 12.8

Step-by-step explanation:

Since you are missing 1 side, set up a proportion 8 is to 3.2 as 32 is to x, so

[tex]\frac{8}{3.2} =\frac{32}{x}[/tex] so solve for x by cross multiplying 8x = 102.4, so x = 12.8

The vertices of a shaded square are the midpoints of the sides of square ABCD. The length of the diagonal of square ABCD is 6 inches.

Answers

Answer:

A=13.47 in.

P=14.68 in.

Step-by-step explanation:

First, we have to figure out the sides of square ABCD. The diagonal forms the hypotenuse of a right equilateral triangle.

a²+a²=6²

2a²=36

a²=18

a=√18

a=4.24

Half of 4.24 would be the distance From each corner of ABCD to the neighboring midpoints.  (2.12)

2.12²+2.12²=c²

4.49+4.49=c²

13.48=c²

√13.48=c

3.67=c

Now that we know each side of the shaded square, we can get the area and perimeter.

A=3.67x3.67=13.47

P=3.67x4=14.68

Answer:

y = 5.6

Step-by-step explanation:

Use Sine

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

Hope this helps!

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.

What is trigonometry?

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.

A dolphin jumps out of the water. The function h=-16t^2+26t models the height (in feet) of the dolphin after t seconds. After how many seconds is the dolphin at a height of 5 feet.

Answers

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 three sides of AXYZ
measure 13 feet, 17 feet, and
21 feet. IS AXYZ an acute,
right, or obtuse triangle?

Answers

9514 1404 393

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.

the clock was exactly on time at 7am at 1pm the clock was 228 seconds late at that rate how slow was the clock half an hour

Answers

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.

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.

What is an expression?

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
