The area is determined in square units
stira [4]3 years ago

Okie, when you are talking about area, you will have units of course! :-)
So, square units are the units in which describe the area. Let's take a rectangle slab of paper that is 2 inches by 4 inches. Yes, the answer is 8, but what are the units. It is inches squared! Squared units are the units of area.
I hope this helps :-)

WILL GIVE BRAINLIEST: If the graph of 2x+3y − 6=0 is perpendicular to the graph of ax − 3y=5. What is the value of a?
Ilya [14]

Answer:

a = \frac{9}{2}

Step-by-step explanation:

To find the value of a, find the Slope of both the equations.

For lines to be perpendicular to each other    m_{1}m_{2}  = - 1

For line 1:

2x + 3y − 6 = 0 represent the line in y=mx +c form

3y = -2x + 6

y = \frac{-2}{3} x + \frac{6}{3}

y = \frac{-2}{3} x + 2

m_{1} = \frac{-2}{3}

For line 2:

ax - 3y = 5

ax = 5 + 3y

ax - 5 = 3y

y = \frac{ax}{3} - \frac{5}{3}

m_{2} = \frac{a}{3}

Apply the condition of perpendicularity:

\frac{-2}{3} * \frac{a}{3} = - 1

\frac{2a}{9} = 1

a = \frac{9}{2}

What is the square root of 28x to the third power y to the third power
Colt1911 [192]

Hello!

√28x³y³ is equal to 2xy\sqrt{7xy}

We can find this solution through the following steps.

  1. Rewriting the equation by factoring 4 from 28, factoring out x², and factoring out y²
  2. We then can rewrite 4 as 2² in our equation, leaving us with \sqrt{2^{2}*7*(x^{2}x)*y^{2}y }
  3. We will then move our x and 7, and rewrite 2^{2}*x^{2}* y^{2} as (2xy)^{2}
  4. We can then pull the terms from the radical leaving us with 2xy\sqrt{7xy}

BRAINLIEST AND 30 POINTS!!! HURRY!!
Gekata [30.6K]

Answer:

C. 72

Step-by-step explanation:

the answer is C because if you divide 84 by 7 you get 12 so you then multiply 6 by 12 and get 72. the answer could not be negative 72 because that would then make the equation positive.

The function intersects its midline at (-1.25,-3) and a maximum point at (0,4) Find a formula for f(x) Give an exact expression.
stellarik [79]

Answer:  y = 7cos(0.4π x) - 3

<u>Step-by-step explanation:</u>

The equation of a cosine function is:    y = A cos(Bx - C) + D    where

  • Amplitude (A) is the distance from the midline to the max (or min)
  • Period (P) is the length of one cosine wave   -->   P = 2π/B
  • Phase Shift (C/B) is the horizontal distance shifted from the y-axis
  • Midline (D) is the vertical shift. It is equal distance from the max and min

<u>Midline (D) = -3</u>

(-1.25, -3) is given as a point on the midline.  We only need the y-value.

<u>Horizontal stretch (B) = 0.4π</u>

The max is located at (0,4) and also at (5, 4).  Thus the period (length of one wave) is 5 units.

P=\dfrac{2\pi}{B}\qquad \rightarrow \qquad 5=\dfrac{2\pi}{B}\qquad \rightarrow \qquad B=\dfrac{2}{5}\pi          →     B = 0.4π

<u>Phase Shift (C) = 0</u>

The max is on the y-axis so there is no horizontal shift.

<u>Amplitude (A) = 7</u>

The distance from the midline to the max is: A = 4 - (-3) = 7

<u>Equation</u>

Input A = 7, B = 0.4π, C = 0, and D = -3 into the cosine equation.

            y = A cos(Bx - C) + D

            y = 7cos(0.4π x - 0) - 3

            y = 7cos(0.4π x) - 3
