f(x) = 9(9 + x)(10)
f(5) = ? ​

Answer: The second option would be the answer

Step-by-step explanation:

Factoring the number is just listing all the whole numbers it can be divided by, and in this case it includes the variable. 16a is dividable by 1, 2, 4, 8, 16, and a; since 16a / a = 16. Apply this to 18b, and 1, 2, 3, 6, 9, 18, and b.

[tex]\boxed{imperturbability}[/tex]

Answer:

of the question is in the simple 0.45

Given :

⠀

To Find :

⠀

Solution :

We know that,

[tex]\qquad { \pmb{ \bf{Length \times Width = Area_{(rectangle)}}}}\: [/tex]

So,

Let's assume the width of the rectangle as x and the length will be (x + 2).

⠀

Now, Substituting the given values in the formula :

[tex]\qquad \sf \: { \dashrightarrow (x + 2) \times x = 48 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow {x}^{2} + 2x = 48 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow {x}^{2} + 2x - 48 = 0 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow {x}^{2} +8x -6x- 48 = 0 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow {x} (x +8) -6(x+8) = 0 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow (x +8) (x - 6) = 0 }[/tex]

[tex]\qquad \sf \: { \dashrightarrow x = -8, \: \: x = 6 }[/tex]

⠀

Since, The width can't be negative, so the width will be 6 which is positive.

⠀

[tex]\qquad { \pmb{ \bf{ Width _{(rectangle)} = 6\:ft}}}\: [/tex]

[tex]\qquad { \pmb{ \bf{ Length _{(rectangle)} = 6+2=8 \: ft}}}\: [/tex]

Answer:

( -2 , 1 )

Step-by-step explanation:

Add the 2 equations downwards.

( -x+4y=6 ) + ( 2x-y=-5 )...consider the sign of each term.

= x + 3y = 1

Put -2 in x because that's where the graph above shows an intersection of the 2 equations.

-2 + 3y = 1

3y = 3

y = 1.

( x , y) = ( -2 , 1 )

Answer: y=-5x-36

Step-by-step explanation:

In order for two lines to be parallel they need to have the same slope. so the slope (m) of the new line needs to be -5.

slope(m) =-5

and the point (-8,4) is given to us. we can create a new equation for a line using the point slope formula because we have a slope (m=-5) and a point (-8,4)

point slope formula: y-y1=m(x-x1)    

y-4=-5(x--8)

simplify and pay attention to negative signs

y-4=-5(x+8)

y-4=-5x-40

y=-5x-36

Hi!

We are given the information found in the picture below.

Note: The directions aren't correct, but the triangle works for this problem.

The "direct path" is the hypotenuse of this triangle.

To find this, we use the Pythagorean Theorem, where [tex]a[/tex] and [tex]b[/tex] are 2 legs of the triangle, and [tex]c[/tex] is the hypotenuse, aka the longest side of any triangle:

[tex]a^2+b^2=c^2[/tex]

We know [tex]a[/tex] and [tex]b[/tex] and want [tex]c[/tex]

[tex]4^2+5^2=c^2[/tex]

[tex]16+25=c^2[/tex]

[tex]41=c^2[/tex]

Therefore, [tex]c[/tex] is approximately [tex]6.403[/tex]

Answer:Four heads trust me.

Answer:

x = 25

Step-by-step explanation:

ΔBDR ~ ΔQDC

so

(24 + 40)/(15 + x) = 40/x

or

(24 + 40)/40 = (15 + x)/x

24/40 + 40/40 = 15/x + x/x

3/5 + 1 = 15/x + 1

3/5 = 15/x

Cross multiply,

3x = 15*5 = 75

x = 75/3 = 25

Answer: 32

Step-by-step explanation:

We can write the problem like this:

[tex]\frac{75}{100}x=24[/tex]

Then, we can multiply 100 to the equation:

[tex]75x=2400[/tex]

Now, we can divide 2400 and 75:

[tex]x=32[/tex]

Now we can conclude that the amount of students is 32.

9 bags sorry for the other answer

she has 7 boxes at home, then she goes and buys 6 more from the store, now she has 7 + 6 = 13 boxes of chips, each box of chip has 13 bags, so the total amount of potato chips I guess is 13 * 13 = 169 bags total.

So she split it even among her 9 students, so how many times does 9 go into 169?  169 ÷ 9, has a quotient of 18 with a remainder of 7.

18 * 9 = 162, plus 7 = 169, which is the total amount of potato chips bags.

Answer:

y-intercept:  (0, 75) ⇒ y = 75

x-intercepts:  (3, 0) and (5, 0) ⇒ x = 3 and x = 5

vertex: (4, -5)

Step-by-step explanation:

Let the x-axis be the ground (when y = 0).  Therefore underground when y < 0 and overground when y > 0

The function is a quadratic:  f(x) = ax² + bx + c

If the coaster enters the tunnel three seconds after the first descent starts and stays in the tunnel for a total of 2 seconds, then y = 0 when x = 3 and x = 5

Also, when x = 1, y = 40

Solve 2 equations simultaneously:

⇒ a = 5  b = -40  c = 75

⇒ f(x) = 5x² - 40x + 75

y-intercept

when x = 0

⇒ f(0) = 5(0²) - 40(0) + 75 = 75

⇒ y-intercept = (0, 75)

x-intercepts

x = 3 and x = 5

Vertex

If the x-intercepts are when x = 3 and x = 5, then vertex is when x = 4

⇒ f(4) = 5(4²) - 40(4) + 75 = -5

⇒ vertex = (4, -5)

Answer:

2/3

Step-by-step explanation:

2/3 is greater because 2/4 = 1/2 and 2/3 is a bit greater than 1/2.

Using the normal distribution and the central limit theorem, it is found that there is a:

a) 0.1813 = 18.13% probability that a person selected at random will score between 240 and 270 on the test.

b) 0.4501 = 45.01% probability that the mean score for the sample will be between 240 and 270.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem:

Item a:

The probability is the p-value of Z when X = 270 subtracted by the p-value of Z when X = 240, hence:

X = 270:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{270 - 250}{65}[/tex]

[tex]Z = 0.31[/tex]

[tex]Z = 0.31[/tex] has a p-value of 0.6217.

X = 240:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{240 - 250}{65}[/tex]

[tex]Z = -0.15[/tex]

[tex]Z = -0.15[/tex] has a p-value of 0.4404.

0.6217 - 0.4404 = 0.1813.

0.1813 = 18.13% probability that a person selected at random will score between 240 and 270 on the test.

Item b:

We have a sample of 7, hence:

[tex]n = 7, s = \frac{65}{\sqrt{7}} = 24.57[/tex]

X = 270:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{270 - 250}{24.57}[/tex]

[tex]Z = 0.81[/tex]

[tex]Z = 0.81[/tex] has a p-value of 0.7910.

X = 240:

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{240 - 250}{24.57}[/tex]

[tex]Z = -0.41[/tex]

[tex]Z = -0.41[/tex] has a p-value of 0.3409.

0.7910 - 0.3409 = 0.4501.

0.4501 = 45.01% probability that the mean score for the sample will be between 240 and 270.
