Answer:

= 28.2857 Cm²

Step-by-step explanation:

π × (R² - r²)

22/7 × (10² - 8²)

22/7 × (5-4) × (5+4)

22/7 × 1 × 9

= 28.2857 Cm²

Two runners are saving money to attend a marathon. The first runner has $112 in savings, received a $45 gift from a friend, and

saul85 [17]

The right answer is: d.112 + 25m + 45 = 50 + 60m

Step-by-step explanation:

Let m be the number of months

For First Runner:

He already has 112 in savings and got 45 from a friend so these will be constant values and as he will be saving $25 each month so

$112+45+25m$

For Second Runner:

He already has $50 in saving and ill save 60 each month so

$50+60m$

In order to find that when there accounts will have same amount, the expressions for both will be put equal

$112+45+25m=50+60m$

The value of m will give us the number of months after which the accounts of both runners will have same amount.

Hence,

The right answer is: d.112 + 25m + 45 = 50 + 60m

A ball is dropped from the ground. T represents the time in seconds. To find the time you can you the equation Y= -16t^2 +44t. H

bagirrra123 [75]

Answer:

2.75 seconds.

Step-by-step explanation:

We have been given that a ball is dropped from the ground. T represents the time in seconds.

To find the time when the ball was in air, we will equate height of ball with 0 and solve for t.

$-16t^2+44t=0$

Upon dividing both sides by 4, we will get:

$-4t^2+11t=0$

$-t(4t-11)=0$

$-t=0\text{ (or) }(4t-11)=0$

$t=0\text{ (or) }4t-11=0$

$t=0\text{ (or) }4t=11$

$t=0\text{ (or) }t=\frac{11}{4}$

$t=0\text{ (or) }t=2.75$

Since our given function is a downward opening parabola, so ball will be in air between both t-intercepts.

Since the ball touches the ground at 2.75 seconds, therefore, the ball would be in air for approximately 2.75 seconds.

Which graph represents the function f(x) =-lx-2l-1

zimovet [89]

It’s the second one from the right

Since there’s a - behind x it means it has to be facing down so it’s either 2 or 4

Now it’s x-2 and we know that x moves the opposite so it needs to move 2 to the right so the answer is 2
