1 is 70 because the triangle has given angles of 45 and 65. If you add them you get 110 and a triangle is equal to 180° so 180-110 is 70.

2 is 65° because a line is equal to 180° as well so since 1 is 70 and being given 45, we add them to get 115 and 180-115 is 65.

3 is 95°because a triangle is equal to 180° so since 2 is 65 and being given 20°, you add those to get 85° and 180-85 is 95.

Answer:

1= 70

2= 65

3= 95

For 1, just solve 180-(65+45) and then for 2, subtract #1 and 45 from 180. Then just solve for #3 by using 180-(#2+20)

Use a graphing utility to graph the function and visually estimate the limits.

The value of the $\lim_{x \to 0} f(x)$ and $\lim_{x \to \frac{\pi }{3} } f(x)$ are 0 and 1.153 .

<h3></h3><h3>What is the limiting value of a function?</h3>

Limiting Value of a Function. The function's limit is the value of the function as its independent variable, such as x approaches a certain value called the limiting value. For simple equations, this is similar to finding out the value of y when x has a unique value.

Given that,

f(x) = $4x cos x$

First to calculate the limit value of the given function at x=0.

$\lim_{x \to 0} f(x)$ = $\lim_{x \to 0} 4x cosx$

= 4×0×1 (∵ cos0 = 1)

$\lim_{x \to 0} f(x)$ = 0

Similarly,

$\lim_{x \to \frac{\pi }{3} } f(x)$ = $\lim_{x \to \frac{\pi }{3} } 4x cosx$

= 4× $\frac{\pi }{3}$ ×cos $\frac{\pi }{3}$

= 4× $\frac{\pi }{3}$ × $\frac{1}{2}$ (∵cos60° = $\frac{1}{2}$ )

$\lim_{x \to \frac{\pi }{3} } f(x)$ = 1.153

Hence, The value of the $\lim_{x \to 0} f(x)$ and $\lim_{x \to \frac{\pi }{3} } f(x)$ are 0 and 1.153.

You are making small pizzas. You have 12 cups of flour. Each pizza crust requires 3/

sveticcg [70]

Hello,

The answer is "16".

Reason:

Just divide 12 by 3/4:

12×4=48÷3=16
1×3=3÷3=1

16/1=16

Therefore they can make 16 pizza crusts!

If you need anymore help feel free to ask me!

Hope this helps!
