Substitute both expressions with x=0 and both of them will equal 2, so the limit should be 2.

A welder is making a metal sphere. The diameter will be 130 inches. What is the surface area of the metal sphere? Use 3.14 for π and round to the nearest tenth.

Answers

Answer:

53092.92 square inches

Kaila wants to borrow $175,000 for her mortgage.Timberwolf Bank offers a 15-year mortgage at an APR of 4.5%.

Answers

Answer:

At the end of the mortgage, $ 293,125 will have been paid.

Step-by-step explanation:

Given that Kaila wants to borrow $ 175,000 for her mortgage, and Timberwolf Bank offers a 15-year mortgage at an APR of 4.5%, to determine the amount to be repaid after the end of the mortgage, the following calculation must be performed:

175,000 x (1 + 15 x 4.5 / 100) = X

175,000 x (1 + 67.5 / 100) = X

175,000 x (1 + 0.675) = X

175,000 x 1,675 = X

293.125 = X

Therefore, at the end of the mortgage, $ 293,125 will have been paid.

A helicopter hovers 1100 The above a small island the figure shows the angle of depression from the helicopter to point P is 46° how far off the coast to the nearest foot is the island?

Answers

Answer:

1232 ft

Step-by-step explanation:

Draw a right triangle. Label the height of the triangle. as 800 since the height of the triangle represents the height of the helicopter above the coast of the island. Label the base length of the triangle as d to represent the distance between the coast of the island and the coast of the mainland, P. The angle of depression from the helicopter to point P is 33° so draw a horizontal dotted line at the location of the helicopter and label the angle made by the horizontal line and the hypotenuse of the right triangle as 33°. The angle of elevation from P to the helicopter and the angle of depression from the helicopter to point P are congruent alternate interior angles so label the angle at P as 33°.  

The side labeled 800 is opposite of P and the side labeled d is adjacent to P so you can use tangent to write an equation. Solve this equation for d and round to the nearest whole number.

For what value of z would the following system of
equations be true for all real integers?
3x-2y = 14
-12x+8y = 8z

Answers

9514 1404 393

Answer:

  z = -7

Step-by-step explanation:

The equations will be true for all real integers when they are a dependent set. That will be the case when the second equation is a multiple of the first.

Already, we observe that the ratios of x- and y-coefficients are -4:

  -12/3 = -4

  8/-2 = -4

The equations will be dependent when the constants have that same ratio:

  8z/14 = -4 . . . . desired ratio

  8z = -56 . . . . . multiply by 14

  z = -7 . . . . makes the equations true for all real numbers

_____

Comment on the question

The system of equations can be made inconsistent (no solutions) or consistent & dependent (infinite solutions) by the choice of z.

However, integer solutions are limited to pairs of the form (2n+2, 3n-4) for integer values of n. The values of x and y are not "all real integers".

Consequently, we have interpreted the question to be asking for the value of z that will make the system of equations have an infinite number of solutions, including both rational and irrational, real and complex values of x and y. They cannot be made to be true for "all real integers" by any choice of z.

Answer:

z = -7 is the answer.

find the arthmetic and the geometric means of 4 and 9

Answers

Answer:

Step-by-step explanation:

first term (a) = 4

last term (b) = 9

Arithmetic mean (AM)

= ( a + b) / 2

= ( 4 + 9 ) / 2

= 13/2

= 6.5

Geometric mean (GM)

The lengths of a certain species of beetles are normally distributed with a mean of 1.9 centimeters and a standard deviation of 0.2 centimeters.

What is the z-score of a beetle of this species with a length of 2.38 centimeters?



Enter your answer in the box.


Enter your answer, rounded to the nearest tenth, in the box.

Answers

Answer:

The z-score of a beetle with a length of 2.38 centimeters is 2.4

Step-by-step explanation:

 

As we know,

z = (x - µ)/σ

x is the length of the beetle species.

µ is the mean length

σ is the standard deviation

Substituting the given values in above equation, we get

 

z = (2.38 - 1.9)/0.2

z = 0.48/0.2

z = 2.4

(x + 3) × (x² + 4)

when putting in order, you want the highest power to the left and then the lowest power to the right.

Answers

Answer:

$120.

Step-by-step explanation:

Just multiply 4 by 5 since it makes 20. Since we know that the price for 4 people is $24, you multiply 24 by 5 since you are paying for 20 people.

It’s 120 all you have to do is divide 24 by 4 to get how much it would be for one person then you multiply that by 20 and you get 120

If a triangle has a center of dilation at the origin and a scale factor of two. if point he was at(-2,-3) what would point A’ would be.

Answers

Answer: Second option.

Step-by-step explanation:

First it is important to remember the definition of Dilation.

A Dilation is defined as a transformation in which the Image (The figure obtained after the transformation) and the Pre-Image (The original figure, before the transformation) have the same shape, but their sizes are different.

In this case you know that the triangle ABC is dilated by a scale factor of 2 with a center of dilation at the origin.

According to the exercise, the point C has these coordinates:

Therefore, in order to find the coordinates of C', you need to multiiply the coordinates of the point C by the scale factor 2.

Then, you get that the coordinates of the point C' are:

because of the law of sines we have

we can also turn this upside down to simplify the calculation.
