The edges of a cube increase at a rate of 2 cm divided by s. How fast is the volume changing when the length of each edge is 40

Dmitry_Shevchenko [17]

Answer:

Step-by-step explanation:

Let the edge of the cube be a .

Given

$\frac{da}{dt} = 2 cm/s$

Volume V = a³

$\frac{dV}{dt} = 3a^ 2\frac{da}{dt}$

= 3a² x 2

= 6a²

If a = 40 cm

$\frac{dV}{dt} = 6 \times 40\times40$

= 9600 cm³/s .

A basketball player makes 60% of his free throws. We set him on the line of free-throw and informed him to shoot free throws unt

pshichka [43]

Answer:

B. 0.03110

Step-by-step explanation:

Given

Probability of Hit = 60%

Required

Determine the probability that he misses at 6th throw

Represent Probability of Hit with P

$P = 60\%$

Convert to decimal

$P = 0,6$

Next; Determine the Probability of Miss (q)

Opposite probabilities add up to 1;

So,

$p + q = 1$

$q = 1 - p$

Substitute 0.6 for p

$q = 1 - 0.6$

$q = 0.4$

Next,is to determine the required probability;

Since, he's expected to miss the 6th throw, the probability is:

$Probability = p^5 * q$

$Probability = 0.6^5 * 0.4$

$Probability = 0.031104$

Hence;

1)When adding two negative numbers, _________ the absolute value of the numbers and keep the negative sign.

butalik [34]

1) add.

for example -1 + -2 = - (||-1| + |-2||), which is -(1+2) or -3

2) subtract

for example 4 + -7 = -(||-7| + |4||), which is - |7 - 4| or -3

3) change
for example 3 - (- 2) = 3 + 2

4) -10

the sum is -10.25, which is closest to -10
