Answer:

if 3 equal 8 , then 600 will be 1600.

The angle measures are;

Angle 7  is 40° = Angles 8 : supplementary

Angle 3 is 40° = Angles 8: supplementary angles

Angle 5 = 140°  = Angle 8; corresponding angles

Angle 1 = 140°  = Angle 8; corresponding angles

Angle 6 = 40°  = Angle 8; supplementary angles

Angle 2 = 140°  =  Angle 8; corresponding angles

Angle 4 = 140°  Angle 8; corresponding angles

Given that angle 8 measures 140 degrees

It is important to note that angles on a straight line equals 180 degrees

Then,

angle 7 + angle 8 = 180°

Substitute the values of angle 8

Angle 7 + 140 = 180

Angle 7 = 180 - 140

Angle 7 = 40°

Thus, If angle 7  is 40° then angle 3 is 40°, corresponding angles

Angle 5 = Angle 8; corresponding angles

Angle 1 = Angle 8; corresponding angles

Angle 6 = Angle 7; corresponding angles

Angle 2 = Angle 8; corresponding angles

Angle 4 = Angle 8; corresponding angles

The value of the expression is 0 without calculation.

We have to find the exact value of

sin 26° - cos 26°

From the trigonometric function we know that:

cos (90°-Ф) = sinФ and,

sin(90° -Ф) = cosФ

By this, we have an expression that,

=sin 26° - cos 64°

=sin 26° - cos (90° - 26)

=sin 26° - sin 26°

=0

Therefore the value of sin 26° - cos 64° =0.

Step-by-step explanation:

The dimensions of the rectangular garden are 29 feet by 23 feet .

A rectangle is a quadrilateral with parallel opposite sides and equal angles. There are a lot of rectangular objects all around us. Any rectangular form's two defining characteristics are its length and width. A rectangle's longer and shorter sides are its width and length, respectively.

The area of a rectangle is given by length × width

Now the given area of the rectangle is 667 ft² .

Let the width of the rectangle is x ft. Therefore length = x + 6

Now area of the rectangle is x (x+6) = x² + 6 x

Therefore x² + 6 x = 667

or,  x² + 6 x - 667  = 0

or, (x-23)(x+29) = 0

Either x = 23 or x = -29(not possible)

Hence the width is 23 feet.

Length = 23 + 6 = 29 feet

Therefore the dimensions of the rectangle are 29 feet by 23 feet .

The proportion of people surveyed would be willing to pay more than $6.75 for a sandwich is 94.4%.

The normal distribution, also recognized as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data far from the mean.

As, for the given value in the question;

The formula for finding the z-score is;

z = (x - μ)/s

where,

n = sample size ( = 528)

σ = standard deviation ( = 1.19)

μ = mean of the sample (= 6.56)

Put the values and fine z-score.

z = (x - μ)/s

z = (6.75 - 6.56)/1.19

z = 0.19/1.19

z = 0.159

For the probability; see the p-value from the positive z-score table.

p(z > 0.159) = 0.944

p(z > 0.159) = 94.4%

Thus, the probability that the people would be willing to pay more than $6.75 for a sandwich is calculated as 94.4%.

APY for Kevin's account = 1.67%

The interest on a loan or deposit that is computed based on both the original principle and the accumulated interest from prior periods is known as compound interest (also known as compounding interest). Compared to simple interest, which is computed just on the principal amount, it will cause a sum to increase more quickly.

The frequency of compounding determines the pace at which compound interest accumulates. The compound interest increases with the number of compounding periods.

APY = [tex](1 + \frac{r}{n})^{n} - 1[/tex]  =   [tex](1 + \frac{1.667}{365})^{365} - 1[/tex]  =  1.0167 - 1 = 0.0167

Step-by-step explanation:

we get the points with extreme values as the 0 points of the first derivative of the function.

h'(t) = 592 - 32/7 t = 0

592 = 32/7 t

4144 = 32t

t = 129.5 seconds

so, it will reach its max. height after 129.5 seconds.

The time that the ball reaches its maximum height is 129.5 seconds.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The height above the lunar surface (in feet) after ‘t’ seconds is given by the formula;

⇒ h =592t - 16/7t²

Now,

We have to find the derivative of above formula and equate to zero for the maximum time as;

⇒ h =592t - 16/7t²

⇒ h' =592 - 16/7 × 2t = 0

⇒ 592 - 32/7 t = 0

⇒ 32/7 t = 592

⇒ 32t = 592 × 7

⇒ 32t = 4,144

⇒ t = 4,144/32

⇒ t = 129.5 seconds.

Thus, The time that the ball reaches its maximum height is 129.5 seconds.

Answer:

A Cartesian Plane is a plane in Geometry which is an flat surface of infinite size. It has two number lines that intersect at right angles at their zeros. One number line is horizontal, and the other number line is vertical. The point of intersection is the zero of each line. In the horizontal line, the numbers increase to the right. In the vertical line, the numbers increase up. The horizontal line is called the x axis. The vertical line is called the y axis. The center of the Cartesian Plane is the intersection of the two axes, the two number lines, and is called the origin. Points on the Cartesian Plane are described with two numbers in parentheses separated by a comma. The position of the point in the Cartesian Plane is given by the first number, called the x-coordinate, telling us the number of units to the right (positive) or left (negative) of the origin and by the second number, called the y-coordinate, telling us the number of units up (positive) or down (negative) from the origin.
