Let Carl's age be c and Ben's age be 3c.

Equation:

3c = 2c + 2

=> 3c - 2c = 2

=> c = 2

So, Carl is 2 years old.

Tina throws a baseball straight up from a height of 3 feet and at a speed of 50 feet per second. The height of the ball in feet

vodka [1.7K]

Answer:

9 feet

Step-by-step explanation:

The height of the ball in feet is given by the polynomial:

$h(t) = -16t^2+50t+3$

where t is the time in seconds.

After 3 seconds, t = 3:

$h(3) = -16(3)^2 + 50(3) + 3 \\\\h = -144 + 150 + 3 = 9 feet$

The height of the ball after 3 seconds is 9 feet.

HELP!!!! Choose the correct answer. Which expression, when evaluated,

blagie [28]

We will check each options and verify it

(a)

$18-2m$

we can plug m=2

$18-2\times 2$

$18-4$

$14$

so, this is FALSE

(b)

$7x-\frac{x}{3} >19$

we can plug x=3

$7\times 3-\frac{3}{3} >19$

$21-1 >19$

$20 >19$

so, this is TRUE

(c)

$6x-1>4x+5$

we can plug x=3

$6\times 3-1>4\times 3+5$

$18-1>12+5$

$17>17$

so, this is FALSE

(d)

$2x^2-3x+1$

now, we can plug x=2

$2(2)^2-3(2)+1$

$8-6+1$

$3$

So, this is FALSE
