If you follow PEMDAS
P-parentheses
E-exponent
M-multiplication
D-divide
a-addition
s-subtraction
then you should look in the parentheses and multiplying 3x should be your first step IF you know x
hope this helps :)

A large explosion causes wood and metal debris to rise vertically into the air with an initial velocity of 96 feet per second. T

Vladimir [108]

Answer:

the height after 2 seconds will be 128 feet

Step-by-step explanation:

Data provided in the question:

Initial velocity = 96 feet per second

The function of height of falling debris above the ground is given as:

h(t) = 96t - 16t²

A) To find height after time t = 2 seconds

substituting the value of time in the above function, we get

h(t) = 96 × 2 - 16 × 2²

h(t) = 192 - 16 × 4

h(t) = 192 - 64

h(t) = 128 feet

Hence,

the height after 2 seconds will be 128 feet

Lorico [155]

<h3><u>Given</u>:-</h3>

Volume 6,900 cm^3
Length = 23 cm
Width = 10cm

Height of box ??

<h3><u>Solution</u>:-</h3>

$\\\diamond{\underline{\underline{\sf {\;\; Calculating\; Height\; of \; box :-}}}}\\$

$\\ \pink \star \: \: {\underline{\boxed {\bf{ Volume_{ \red{ \{Rectangle \}}} \: = l \times w \times h }}} }\; \red\bigstar \\$

Where,

» l denotes Length
» w denotes Width
» h denotes Height

$\\ \sf \implies \: {Volume_{ \red{ \{Rectangle \}}} \: = l \times w \times h} \\$

$\\ \sf \implies \: { 6,900 \: = \: 23 \: \times \: 10 \: \times h} \\$

$\\ \sf \implies \: { 6,900 \: = \: 230 \: \times \: h} \\$

$\\ \sf \implies \: { \: h \: = \: \frac{6900}{230} \: } \\$

$\\ \sf \implies \: { \: h \: = \: 30 \: {cm }^{3} \: } \\$

$\\ \implies{\underline{\boxed{\frak { Height = 30 \: cm^3 }}}} \; \purple\bigstar \: \\$

$\\\qquad \rule{120pt}{3pt}\\$

Therefore , the Volume of the Box is 30 cm ³.
