If 19 are turkey and 9 are bologna, that means that 12 are tuna fish (19 + 9 = 28. 40 - 28 = 12)

12/40 = 0.3, or 30%

The answer is 30%.

If a pond has a major axis of 68 feet and a minor axis of 32 feet how far apart are the foci

Bogdan [553]

Answer:

The distance between foci is 60 feet

Step-by-step explanation:

we are given

a pond has a major axis of 68 feet

so, $a=\frac{68}{2} =34$

a minor axis of 32 feet

so, $b=\frac{32}{2} =16$

now, we know ellipse formula

$c^2=a^2-b^2$

where

c is the distance between center and focus

so, we can plug it and find c

$c^2=34^2-16^2$

$c=30$

Distance between foci is

$=2c$

$=2\times 30$

$=60$

Given the function f(x)=x^2 and the transformed function g(x)=4x^2+1, explain how the parent function was transformed.

satela [25.4K]

Answer:

In the function g(x) = 4x² + 1, <em>4</em> means that all the points in the parent function were multiplied by 4. <em>+ 1 </em>means that the parent graph will shift up by 1.

iVinArrow [24]

Step-by-step explanation:

3x - y = 74

4y = x

Replace x in the first expression by 4y

3x - y = 74 ➡ 3(4y) - y = 74

12y - y = 74

11y = 74

y = 74/11 we can use this to find x

4y = x

4 × 74/11 = x

296/11 = x
