Solve a,b,c,d please

sdas [7]

For each, replace x with the number in the parenthaseses

a.
$f(2.5)=\frac{1}{2.5-2}=\frac{1}{0.5}=2$

b.
$f(1.75)=\frac{1}{1.75-2}=\frac{1}{-0.25}=-4$

c.
$f(2)=\frac{1}{2-2}=\frac{1}{0}=undefined$
division by 0 is not allowed so it is undefined at the point

d. because division by 0 is not allowed

Use the order of operations to evaluate this expression: 7 + (5 – 9)2 + 3(16 ÷ 8).

Jet001 [13]

Remember to use PEMDAS when solving.

= 7 + (5 – 9)2 + 3(16 ÷ 8)

= 7 + (-4)2 + 3(2)

= 7 + (-8) + 6

= -1 + 6

= 5

Best of Luck!

A ball is thrown into the air. The path it takes is modeled by the equation: -3t+24t = h, where t is the time in seconds and h i

astra-53 [7]

Given:

The given equation is:

$-3t^2+24t=h$

Where, t is the time in seconds and h is the height of the ball above the ground, measured in feet.

To find:

The inequality to model when the height of the ball is at least 36 feet above the ground. Then find time taken by ball to reach at or above 36 feet.

Solution:

We have,

$-3t^2+24t=h$

The height of the ball is at least 36 feet above the ground. It means $h\geq 36$ .

$-3t^2+24t\geq 36$

$-3t^2+24t-36\geq 0$

$-3(t^2-8t+12)\geq 0$

Splitting the middle term, we get

$-3(t^2-6t-2t+12)\geq 0$

$-3(t(t-6)-2(t-6))\geq 0$

$-3(t-2)(t-6)\geq 0$

The critical points are:

$-3(t-2)(t-6)=0$

$t=2,6$

These two points divide the number line in 3 intervals $(-\infty,2),(2,6),(6,\infty)$ .

Intervals Check point $-3(t-2)(t-6)\geq 0$ Result

$(-\infty,2)$ 0 $(-)(-)(-)=(-)$ False

$(2,6)$ 4 $(-)(+)(-)=+>0$ True

$(6,\infty)$ 8 $(-)(+)(+)=(-)$ False

The inequality is true for (2,6) and the sign of inequality is $\geq$ . So, the ball is above 36 feet between 2 to 6 seconds.

$6-2=4$

Therefore, the required inequality is $-3t^2+24t\geq 36$ and the ball is 36 feet above for 4 seconds.

Answer:

1 is multiplication

2 is division

3 is parentheses

4 is exponents

5 is parentheses

6 is exponents

7 is G.

8 is F.

9 is H.

10 is A.

11 is C.

12 is E.

13 is D.

14 is B.

Step-by-step explanation:

PEMDAS

parentheses

exponents

multiplication

division

addition

subtraction

do it in that order. but multiplication and division are on the same level so whichever comes firsts gets solved first and addition and subtraction are on the same level so whichever that come first gets solved first
