a basketball player has already scored 56 points in a game the team record for point a in a game is 72 which equation would allow you to find out how many more points the player needs to tie the record

Answer:

The coefficient of x²y³ is 40.

Step-by-step explanation:

The binomial expansion is defined as

[tex](a+b)^n=^nC_0a^n+^nC_1a^{n-1}b+...+^nC_ra^rb^{n-r}+....+^nC_nb^n[/tex]

The expression is

[tex](2x+y)^5[/tex]

Expand the binomial expansion.

[tex](2x+y)^5=^5C_0(2x)^5+^5C_1(2x)^{4}(y)+^5C_2(2x)^{3}(y)^2+^5C_3(2x)^{2}(y)^3+^5C_4(2x)^{1}(y)^4+^5C_5(y)^5[/tex]

Combination formula:

[tex]^nC_r=\frac{n!}{r!(n-r)!}[/tex]

[tex](2x+y)^5=32 x^5 + 80 x^4 y + 80 x^3 y^2 + 40 x^2 y^3 + 10 x y^4 + y^5[/tex]

Therefore the coefficient of x²y³ is 40.

Answer:

Lisa score 575 points and Kate scored 325 points.

Step-by-step explanation:

We are given the following information:

Total score for Lisa and Kate is 900 and Lisa scored 250 more points than Kate.

Scores for Lisa and Kate can be expressed with the help of two equations:

[tex]L + K = 900\\L = K + 250 \Rightarrow L-K = 250[/tex]

Solving these equations we have:

[tex]L + K + L - K = 900 + 250\\2L = 1150\\L = 575\\K = 575 - 250 = 325[/tex]

Hence, Lisa score 575 points and Kate scored 325 points.

The success would expect are 1200.    

Step-by-step explanation:

Given : If a binomial event has a probability of success of 0.2.

To find : How many successes would you expect out of 6000 trials?

Solution :

The probability of success p=0.2.

The number of trials is n=6000

Since the plate is circular, therefore the area of the plate is jut equal to the area of a circle, so:

Area of plate = πr² = A

Taking the derivative:

dA / dr = 2πr                                                                           ---> 1

By the idea of partial differentiation, the equation can also take in the form of:
dA/dt = dA/dr x dr/dt                                                             ---> 2

Where we are given that:
change in radius over time = dr/dt = 0.02  cm/min
change in area with changing radius = dA/dr = 2πr              ---> from equation 1
at r = 40 
dA/dr = 2π(40) = 80π 

Substituting all the known values into equation 2:
dA/dt = (80π)(0.02)

dA/dt = 1.6π cm^2 /s = 5.03 cm^2/s

To determine how many minutes each boy plays in a 36-minute gym period with 24 boys wanting to play basketball, with only 10 able to play at a time, each boy would play for 15 minutes.

Explanation:

To find out how many minutes each boy plays in a 36-minute gym period with 24 boys and 10 playing at a time:

Calculate the total time for 24 boys: 24 boys / 10 boys playing at a time = 2.4 sets.

Divide the gym period by the number of sets: 36 minutes / 2.4 sets = 15 minutes per set.

Answer:

The power of 10 would be -5

Step-by-step explanation:

In scientific notation we write a very small or very large number as the product of a number from 0 to 9 and the exponent of 10,

For getting a number between 0 to 9 if the decimal shifted right side then the exponent of 10 is negative power of total shifting while if the decimal shifted left side then the exponent of 10 is positive power of total shifting.

Here, the number is,

0.000028

By the above explanation, we need to shift the decimal five time to the right so the exponent of 10 would be 5.

[tex]\implies 0.000028=2.8\times 10^{-5}[/tex]

After 5 year term, the distance covered is 140000 km, the charge paid is, $1200

The fundamental concept of repeatedly adding the same number is represented by the process of multiplication. The results of multiplying two or more numbers are known as the product of those numbers, and the components that are multiplied are referred to as the factors.

Given that,

In lease agreement, the distance allowed 25000 km per year for free

After that the charge will be $0.08 per km

After 5 year term, you drove a total of 140000 km

The owed amount  = ?

So, in 5 year term the distance which is free according to agreement,

⇒   5 × 25000

⇒    125000

Now, the distance for which charge has given

⇒   140000 - 125000

⇒   15000

Charged amount = $0.08 per km

The owed amount  =  0.08 × 15000

                                =   $1200

Hence, the amount owed is $1200

The simplified form of given factorial expression is (N+3)!.

Step-by-step explanation:

The given expression is

[tex]\frac{(N+4)!}{N+4}[/tex]

The n! is defined as

Therefore the simplified form of given factorial expression is (N+3)!.

The value of a larger number is 39 and the smaller number is 25.

Given that,

The sum of the two numbers is 64.

And, the smaller number is 14 less than the larger number.

Let us assume that,

The larger number is = x

Then, the value of smaller numbers = x - 14

Since the sum of the two numbers is 64.

Hence we get;

x + (x - 14) = 64

2x - 14 = 64

2x = 64 + 14

2x = 78

x = 78/2

x = 39

Thus, The larger number is = 39

Then, the smaller number = 39 - 14

                                            = 25

Answer:

D. 99.9936%.

Step-by-step explanation:

We have been given that the length of a screw produced by a machine is normally distributed with a mean of 0.65 inches and a standard deviation of 0.01 inches.

To find the percent of screws that are between 0.61 and 0.69 inches, first of we will find z-score for our given raw scores using z-score formula.

[tex]z=\frac{x-\mu}{\sigma}[/tex], where,

[tex]z=\text{z-score}[/tex],

[tex]x=\text{Raw-score}[/tex],

[tex]\mu=\text{Mean}[/tex],

[tex]\sigma=\text{Standard deviation}[/tex].

Now let us find z-score corresponding to our given raw scores.

[tex]z=\frac{0.61-0.65}{0.01}[/tex]

[tex]z=\frac{-0.04}{0.01}[/tex]

[tex]z=-4[/tex]

Now let us find z-score for raw score 0.69.

[tex]z=\frac{0.69-0.65}{0.01}[/tex]

[tex]z=\frac{0.04}{0.01}[/tex]

[tex]z=4[/tex]

Now we will use formula to find the probability between two z-score as:

[tex]P(a<z<b)=P(z<b)-P(z<a)[/tex]

Upon substituting our given values in above formula we will get,

[tex]P(-4<z<4)=P(z<4)-P(z<-4)[/tex]

Using normal distribution table we will get,

[tex]P(-4<z<4)=0.99997-0.00003[/tex]

[tex]P(-4<z<4)=0.99994[/tex]

Now let us convert our answer into percent by multiplying 0.99994 by 100.

[tex]0.99994\times 100=99.994\%[/tex]

Therefore, 99.994% of screws are between 0.61 and 0.69 inches and option D is the correct choice.

The bridge builder used the tangent function to calculate the width of the river. The equation tan(43) = width/90 was set up, and solving for width gives an answer of approximately 91.6 feet.

The question gives us a right triangle set up, where point A is where the builder starts, point B is where he walks to, and point C is directly across the river. We can use trigonometry, specifically the tangent function, to find the unknown side. In a right triangle, the tangent of an angle is equal to the ratio of the opposite side (the side across from the angle) to the adjacent side (the side next to the angle).

The angle (θ) in this case is 43 degrees, the side adjacent to the angle is the walk of 90 feet, and the side opposite the angle is the width of the river, which we'll call 'w'. So we get the equation: tan(43) = w/90. Solving for 'w' gives us the width of the river.

Therefore, w = 90 * tan(43), which calculates to approximately 91.6 feet. So the width of the river is approximately 91.6 feet.

Final answer:

The smallest number in the domain of the composite function f^o g,  is -8.

Explanation:

To find the smallest number that is in the domain of the composite function fo g, we need to consider the domains of the individual functions f(x) and g(x). First, since f(x) = √7x, f is only defined for x ≥ 0, as the square root function requires non-negative input. Secondly, g(x) = x+8 is defined for all real numbers, as it's a linear function.

However, the composite function f(g(x)) will also require that the output of g(x) be non-negative, because this output becomes the input for f(x). Thus, we need to find the smallest x such that g(x) is non-negative, which occurs when x+8 ≥ 0. Solving for x gives us x ≥ -8.

Hence, the smallest x in the domain of fo g is -8.
