Answer: 1 1/12 (aka 13/12)

Step-by-step explanation: First, I did 3 x 1/4 (3/4) and with 3/4, I used the denominator (4) and multiplied both the numerator and denominator (with this I used 1/3) and multiplied 3 x 4 and 1 x 4 and got 4/12. Now I take the denominator of 3 (from 1/3) and multiply the numerator and denominator from the 3/4, and 3 x 3 and 3 x 4 which got me 9/12. Lastly, I did 9/12 and 4/12 and got 13/12 which is just 1 1/12

Answer:

continuous.

Step-by-step explanation:

Given function is $f(x)=5x^4-9x^3+x-7$ .

and value of a = 7.

Now we need to find if the given function $f(x)=5x^4-9x^3+x-7$ is continuous or not.

By definition of continuity, we know that a function is continuous at a given point if both left and right hand limits are equal.

Left Hand Limit = LHL

$LHL=\lim_{x\rightarrow 7^-}f(x)=5(7)^4-9(7)^3+(7)-7=8918$

Right Hand Limit = RHL

$RHL=\lim_{x\rightarrow 7^+}f(x)=5(7)^4-9(7)^3+(7)-7=8918$

Since both limits are equal at a=7 so we can say that given function is continuous at a=7

the slide at the playground has a height of 6 feet.The base of the slide measured on the ground is 8 feet.what is the length of

NemiM [27]

The formula for finding the length is
${a}^{2} + {b}^{2} = {c}^{2}$
All we have to do is plug in the numbers.

${6}^{2} + {8}^{2} = {c}^{2}$
36 + 64 = 100

Since 100 =
${c}^{2}$
we have to find the square root.

$\sqrt{100} = 10$

The length of the slide is 10 feet.
