By order of operations, you compute the value of the expression in the parentheses first:

6 * 9 = 54

Next, do multiplication:

54 * 3 = 162

Then, do addition and subtraction:

162 + 9 = 171

171 - 5 = 166

The answer is 166.

1. When a cannonball is fired, the equation of its pathway can be modeled by h = -1612 + 128t.

sashaice [31]

Answer:

The maximum height of the ball is 256m

Step-by-step explanation:

Given the equation of a pathway modelled as pathway can be modeled by h = -16t² + 128t

At maximum height, the velocity of the ball is zero.

velocity = dh/dt

velocity = -32t + 128

Since v = 0 at maximum height

0 = -32t+128

32t = 128

t = 128/32

t = 4seconds

The maximum height can be gotten by substituting t = 4 into the modelled equation.

h = -16t² + 128t

h = -16(4)²+128(4)

h = -16(16)+512

h = -256+512

h = 256m

Mr. Simpson is buying jerseys for his High School football team. Thejerseys cost $0 each and there is a processing fee of $65 to

Rina8888 [55]

ANSWER

The linear equation is: y = 80x + 65

Te cost for 40 football jerseys: $3265

EXPLANATION

Let 'x' be the number of jerseys and 'y' the cost of x jerseys.

Each jersey costs $80, so the cost of x jerseys is 80x. There's also an extra fee for procesing of $65, which is the same no matter how many jerseys they buy.

Therefore, the cost 'y' of x jerseys is:

$y=80x+65$

Now we want to know the cost of 40 football jerseys, so we just have to replace x by 40 and solve:

$\begin{gathered} y=80\cdot40+65 \\ y=3200+65 \\ y=3265 \end{gathered}$

galben [10]

Answer:

$t \leq 18.67\ years$

Step-by-step explanation:

we know that

The simple interest formula is equal to

$A=P(1+rt)$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=?\ years\\ P=\$4,500\\ A=\$7,020\\r=0.03$

The inequality that represented this situation is

$P(1+rt) \leq A$

substitute the values and solve for t

$4,500(1+0.03t) \leq 7,020$

$(0.03t) \leq (7,020/4,500)-1$

$t \leq [(7,020/4,500)-1]/0.03$

$t \leq 18.67\ years$
