Answer:

○ A) 21 ft.²

Step-by-step explanation:

${a}^{2} + 2a \sqrt{ \frac{ {a}^{2}}{4} + {h}^{2} } = S. A. \\ \\ {3}^{2} + 2(3) \sqrt{ \frac{ {3}^{2} }{4} + {2}^{2}} = 24 \\ \\ 24 ≈ 21$

For the scientific notation, write the standard form: 5.61 x 102

Alekssandra [29.7K]

I believe the exponential form above is 5.61 x $10^{2}$

Answer:

561

Step-by-step explanation:

A "scientific notation" is being used in order to express large numbers in its simplest form. This is commonly used in careers that use Mathematics very often like engineers or scientists because it makes their computation easier.

The "standard form" refers to the standard or traditional way of writing the numbers.

In order to get the standard form above, you have to check the "power of the number 10." The exponent above is 2. This means that you have to move the decimal point of 5.61 to the right twice. So, the answer is 561.

Write the equation of a line, in SLOPE INTERCEPT FORM, that is perpendicular to the given equation and passes through the given

adoni [48]

Step-by-step explanation:

slope interception formula is

y-y1=m(x-x1)

where m is m=y-y1/x-x1 in this case m=-2 because the line we are trying to find is parallel to the given one y=-2x-6 where slope k=-2

so the final equation would be

y-1=-2(x-(-4))

y-1=-2x-2*4

y=-2x-8+1=-2x-7
