WHAT IS 5X SOMETHING THAT EQUALS 120 BESIDES 24 X 5? SOMEONE PLEASE

In a right triangle, the hypotenuse has endpoints P(–3, 2) and Q(1, –3). On a coordinate plane, line P Q has points (negative 3,

mrs_skeptik [129]

Answer:

The length of PR is 5 units

Step-by-step explanation:

Here, we want to calculate the length of PR

Since PQ is the hypotenuse, it means that the right-angle would be between lines PR and RQ

Also, since R is on the third quadrant, then its coordinates are (-x,-y)

To get the coordinates of R since we know that we need a right angle, we drop a straight vertical line through P and a straight horizontal line through Q

What this mean is that the coordinates of R will take the x-coordinate of the point P and the y-coordinate of the point Q

Hence, we have that the coordinates of the point R is (-3,-3)

Now, we want to calculate the length of PR

PR will be the distance between the points P and R

Mathematically, to get this, we use the distance formula

That will be;

√(y2-y1)^2 + (x2-x1)^2

Thus, we have

√(2-(-3)^2 + (-3-(-3))^2

= √5^2 + 0^2

= √25 = 5 units

Your apartment is at (0, 0) on a coordinate plane. You want to go to Chicken Shack (CS) and get some tasty chicken tenders, with

Ainat [17]

Answer:

The answer is below

Step-by-step explanation:

The distance between two points on a coordinate plane is given by:

$Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Given the location of the apartment (AP) is at A(0,0), the Chicken Shack's (CS) location is at C(3, 4) and Baskin Robbins (BR) is at the location B(- 4, 4). Hence the following distance are:

$|AB|=\sqrt{(-4-0)^2+(4-0)^2} =4\sqrt{2}\ units\\\\|AC|=\sqrt{(3-0)^2+(4-0)^2}=5\ units \\\\|BC|=\sqrt{(3-(-4))^2+(4-4)^2}=7\ units$

Hence the total distance travelled = distance between the apartment and chicken shack +distance between apartment and Baskin Robbins + distance between Baskin Robbins and chicken shack

total distance travelled = AB + BC + AC = 4√2 + 7 + 5

total distance travelled = 17.66 units

You are planning to build a rectangular vegetable garden with a perimeter of 42 m. the length is twice the width. find the dimen

Mrac [35]

Length - 14 meters

Width - 7 meters

The length is twice the width - 7 times 2 = 14

There are four sides, two 14m and two 7m. 14 x 2 + 7 x 2 = 42

Which of the following is true for f(x)= -2sin(x)-3?

serious [3.7K]

Let's write the general form of the sine curve:

$f(x)=AsinB(x+C)+D$ , where,

A is the amplitude. Also, if A is negative, curve reflects about x axis
B is the compression/stretching factor. It changes the period when it is a value other than 1.
C is the phase shift. It translates curve left or right. Negative value shifts right and positive value shifts left.
D is the vertical shift. It translates curve up or down. Negative value shifts down and positive value shifts up.

Let's check the 4 choices.

A.

Since this curve's A is -2, its amplitude is 2 and range is from -2 to 2. BUT since D value is -3, it shifts vertically 3 units down making the range from -1 to -5. Clearly choice A is not true.

B.

This graph is the graph of $f(x)=-2sin(x)$ shifted 3 units DOWN since D is negative. This choice isn't true.

C.

Because of the - (minus) sign in front of the function, the function is reflected about x-axis, but amplitude doesn't change. Since A value is 2, amplitude is 2. This is true.

D.

Period depends on the B value. Here, B value is 1, so period is normal as the parent function of a sine curve, which is $2\pi$ , NOT $4\pi$ . So this is not correct.

ANSWER: C is true
