A stainless steel patio heater is a square pyramid. The length of one side of the base is 19.6 m. The slant height of the pyrami

aivan3 [116]

Answer:

90.8 m

Step-by-step explanation:

Pythagorean Theorem

A²+B²=C²

slant height = C

A = 19.6/2=9.8m

90.9 in to m = 2.3m

9.8²+B²=2.3²

B²=90.9²-2.3² = 8257.52

B= $\sqrt{8257.52}$ = 90.8

Which equation is a linear function? y=2^x -1 y=x/2-5 y=2/x +3 y=x^2 +7

Umnica [9.8K]

Answer:

Second Choice.

Step-by-step explanation:

$y = mx + b$

That is the linear function. Any coefficients with higher degrees won't be considered as a linear function.

So we can cut out the first and last choice.

Then we have only two choices which are

$y = \frac{x}{2} - 5 \\ y = \frac{2}{x} + 3$

The second equation is called Rational Function where a variable is a denominator.

Therefore, the correct answer is second choice.

Perform the following division:

timofeeve [1]

(33/4) / (2/8)
when dividing with fractions, flip what u r dividing by, then multiply
33/4 * 8/2 = 66/2 = 33...hmm...not an answer choice

let me try something..
(3 3/4) / (2/8) =
15/4 * 8/2 =
30/2 =
15 <====possibly this one if ur problem is : (3 3/4) / (2/8)
