Answer:

9852 Rounded to the nearest whole number.

Step-by-step explanation:

C = 2\pir  Fill in what we know to solve for r

176 = 2\pir  Divide both side by 2\pi

r = 28 rounded to the nearest whole number.

The formula for the area of a circle is

A = 4\pir^{2}

A = 4\pi28^{2}

A = 9852 Rounded to the nearest whole number

EVALUATE THE WORD PROBLEMS
andrezito [222]
Another effective strategy for helping students improve their mathematics performance is related to solving word problems. More specifically, it involves teaching students how to identify word problem types based on a given problem’s underlying structure, or schema. Before learning about this strategy, however, it is helpful to understand why many students struggle with word problems in the first place.

Difficulty with Word Problems

Most students, especially those with mathematics difficulties and disabilities, have trouble solving word problems. This is in large part because word problems require students to:

Y= 16t (squared) +120 what is t
Zina [86]

Answer:

Step-by-step explanation:

hello :

16t²+120 = y

16t² = y -120   so : t² = (y-120)/16

if  :  y-120 ≥ 0        t = ±√((y-120)/16)

Write the slope-intercept form of the equation of each line.
miskamm [114]

Answer:

y = 3x + 2

Step-by-step explanation:

Let's identify two clear points on this line. I can see (0, 2) and (-1, -1)

First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)

Plug in these values:

(-1 - 2) / (-1 - 0)

Simplify the parentheses.

= (-3) / (-1)

Simplify the fraction.

-3/-1

= 3

This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.

y = 3x + b

To find b, we want to plug in a value that we know is on this line: in this case, I will use the first point (0, 2). Plug in the x and y values into the x and y of the standard equation.

2 = 3(0) + b

To find b, multiply the slope and the input of x(0)

2 = 0 + b

Now, we are left with 0 + b.

2 = b

Plug this into your standard equation.

y = 3x + 2

This is your equation.

Hope this helps!
