Can someone find the MAD

X = -2500

This is because:

For this case we must find the value of the variable "x" of the following expression:

[tex]\sqrt {-4x} = 100[/tex]

Now, we square both sides of the equation:

[tex]-4x = 100 ^ 2\\-4x = 10000[/tex]

We divide between -4 on both sides of the equation:

[tex]x = \frac {10000} {- 4}\\x = -2500[/tex]

Answer: Option D

[tex]f(x)=(x+3)^2 -k[/tex]

Step-by-step explanation:

For a quadratic function of the form

[tex]ax ^ 2 + bx + c[/tex]

The x coordinate of the vertice is:

[tex]x =-\frac{b}{2a}[/tex]

In this case the function is:

[tex]f(x)=x^2+6x-2\\\\[/tex]

So

[tex]a=1\\b=6\\c=-2[/tex]

The x coordinate of the vertice is:

[tex]x=-\frac{6}{2*1}\\\\x=-3[/tex]

The y coordinate of the vertice is:

[tex]f(-3) = (-3)^2 +6(-3) -2\\\\f(-3)=-11[/tex]

The vertice is: (-3, -11)

The form e vertice for a quadratic equation is:

[tex]f(x)=(x-h)^2 +k[/tex]

Where

the x coordinate of the vertice is h and the y coordinate of the vertice is k.

Then h=-3 and k =-11

Finally the equation [tex]f(x)=x^2+6x-2\\\\[/tex] in vertex form is:

[tex]f(x)=(x+3)^2 -k[/tex]

Answer:

The correct answer option is D. f(x) = (x + 3)² - 11.

Step-by-step explanation:

We know that the standard form of a quadratic function is given by:

y = ax² + bx + c

The vertex form of a parabola is given by

y = a(x - h)² + k

where (h, k) is the vertex of the parabola.

h = -b / 2a and k = f(h)

In the given equation f(x) = x² + 6x - 2

a = 1, b = 6 and c = -2

Finding h:

h = -6 / (2 × 1)

h = -6/2

h = -3

Finding k:

k = 1(-3)² + 6(-3) + 3

k = 9 - 18 - 2

k = -11

Therefore, the given quadratic function in vertex form: f(x) = (x + 3)² - 11

It is pretty easy.

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest in decimal  

t is Number of Time Periods  

e is the mathematical constant number

we have  

[tex]t=7\ years\\ P=\$1,120\\ r=0.15[/tex]

[tex]A=\$1,120(e)^{0.15*7}=\$3,200.57[/tex]  

Answer:3,200.57

Step-by-step explanation:

Answer:

[tex]x=-15[/tex]

Step-by-step explanation:

[tex]8x+10-2x=4(x-5) \\ \\ 6x+10=4x-20 \\ \\ 2x=-30 \\ \\ x=-15[/tex]

x = -15

First, distribute the 4 to the x - 5 to get 8x + 10 - 2x = 4x - 20.

Now, subtract 4x and 10 from each side to get 4x - 2x = -30

Simplify the subtraction to get 2x = -30.

Divide both sides by 2 to get a final answer of x = -15.

Answer:

Option B) Between 2 & 3 full pitchers

Step-by-step explanation:

Note  In this problem the volume of the pitcher is 1/3 gallon instead of 3 1/3 gallon

The options of the questions are

A) Between 1 & 2 full pitchers

B) Between 2 & 3 full pitchers

C) About 1/2 of a full pitcher

D) About 1/4 of a full pitcher

so

we know that

To find the number of water pitchers Jason will need to fill the water jug, we will divide the amount of water needed to fill the jug by amount of water in the pitcher

[tex](3/4)/(1/3)=9/4\ water\ pitchers[/tex]

Convert to mixed number

[tex]9/4\ water\ pitchers=(8/4)+(1/4)=2(1/4)\ water\ pitchers[/tex]

therefore

Is Between 2 & 3 full pitchers  

Despite having a 3 1/3 gallon pitcher, Jason will only need 3/4 gallon of water to fill his 3/4 gallon jug. The size of the pitcher doesn't matter, only the size of the jug.

Considering that Jason is seeking to fill a 3/4 gallon water jug with a 3 1/3 gallon pitcher, it is evident that the entire capacity of the pitcher will not be required. To determine precisely the volume of water required, we examine the jug's capacity. Given that the jug has a maximum volume of 3/4 gallon, that is the exact volume of water Jason will require to fill it. Regardless of the pitcher's volume, it's the jug's capacity, which is 3/4 gallon, that establishes the quantity of water needed. Consequently, 3/4 gallon is the volume of water he needs to fill the jug.

Answer:

Point (1 , 0.75) lies on the graph of the function ⇒ last answer

Step-by-step explanation:

* Lets revise the exponential function

- An exponential function with base b is defined by f (x) = ab^x  

 where a ≠0, b > 0 , b ≠1, and x is any real number.

- The base, b, is constant and the exponent, x, is a variable.

- The graph of it in the attached figure

- Features (for this graph):

• The domain is all Real numbers.

• The range is all positive real numbers (not zero).

• The y-intercept at (0 , 1.5). Remember any number to

  the power of zero is 1.  

• Because 0 < b < 1, the graph decreases (b = 1/2)

* Now lets check which point lies on the graph

- Substitute the value of x of the point, in the function

- If the answer is the same as y, then the point lies on the graph of

 the function

∵ y = 1.5(1/2)^x

∵ x = -3

∴ y = 1.5(1/2)^(-3) = 187.5 ≠ 1

∴ Point (-3 , 1) does not lie on the graph of the function

∵ x = 2

∴ y = 1.5(1/2)² = 3/8 ≠ 5

∴ Point (2 , 5) does not lie on the graph of the function

∵ x = -2

∴ y = 1.5(1/2)^-2 = 6 ≠ 3

∴ Point (-2 , 3) does not lie on the graph of the function

∵ x = 1

∴ y = 1.5(1/2)^1 = 0.75

∴ Point (1 , 0.75) lies on the graph of the function

[tex]\frac{10}{x} \ miles[/tex]

Step-by-step explanation:

Givens

So, how far does he walk in one hour?

Basically, the question is asking the constant rate of change of the person's position. In other words, it's asking about the man's velocity: how many miles per hour.

The expression that represents this situation is

[tex]\frac{10}{x} \ miles[/tex]

Because, the problem refers to the ratio of change, which is the quotient between the distance traveled and the time that took to travel that distance.

For sin, cos, and tan, let's use an abbreviation.

SOH-CAH-TOA

[tex]sin=\frac{opposite}{hypotenuse}[/tex]

[tex]cos=\frac{adjacent}{hypotenuse}[/tex]

[tex]tan=\frac{opposite}{adjacent}[/tex]

But before that, we should solve for the missing side.

Since this triangle is a right triangle, we can use the Pythagorean Theorem.

[tex]a^2+b^2=c^2 \\ \\ 6^2+8^2=c^2 \\ \\ c^2=36+64 \\ \\ c^2=100 \\ \\ c=10[/tex]

So the hypotenuse is 10.

Let's plug in.

sin θ = 6/10 --> 3/5

cos θ = 8/10 --> 4/5

tan θ = 6/8 --> 3/4

Now for the cosectant, secant, and cotangent, we'll just use the definitions.

Cosectant is hypotenuse over opposite.

Secant is hypotenuse over adjacent.

Cotangent is adjacent over opposite.

So they are basically the inverses.

csc θ = 10/6 --> 5/3

sec θ = 10/8 --> 5/4

cot θ = 8/6 --> 4/3

Answer:

21.9%

Step-by-step explanation:

This involves binomial probability.

n = # of tries:  8

x = # of successes (heads):  3

Use your calculator's probability distribution function binompdf.

Type in binompdf(n, p, x), which in this case would be:

             bionompdf(8, 0.5, 3) = 0.219, or 21.9% (Answer C)

The probability of flipping a coin 8 times and getting heads 3 times is 21.9%. Therefore, option C is correct

To find the probability of flipping a coin 8 times and getting heads 3 times, we need to use the binomial probability formula. The formula is P(x) = (nCx) * p^x * (1-p)^(n-x), where n is the number of trials, x is the number of successful outcomes, p is the probability of success on a single trial, and nCx is the combination notation.

In this case, n = 8, x = 3, and p = 0.5 (since the probability of getting heads on a fair coin is 0.5). Plugging these values into the formula, we get:

P(3) = (8C3) * 0.5^3 * 0.5^(8-3)

= (8!/3!(8-3)!) * 0.5^3 * 0.5^5

= 56 * 0.5^3 * 0.5^5

= 56 * 0.125 * 0.03125

= 0.21875

= 21.9%

£37.80

Step-by-step explanation:

To find the sale price of a jacket during a 30% off sale, first subtract 0.30 from 1.00, obtaining 0.70, and then multiply the regular price (£54) by 0.70:

0.70(£54) = £37.80

The sale price of the jacket after a 30% discount is applied to the original price of £54 is £37.80.

The student's question is about calculating the sale price of a jacket after a discount of 30% is applied to the normal price of £54. This is a typical percentage problem that can be solved using the following steps:

To calculate the discount amount: 30% of £54 = 0.30 × £54 = £16.20.

Then, subtract the discount amount from the original price: £54 - £16.20 = £37.80.

Therefore, the sale price of the jacket is £37.80.

Answer:

8.

Step-by-step explanation:

In all of the steps to solve this specific question, x is a variable to represent the other factor, that we are trying to find out the answer to, and our equation that we need to set up for this problem, is -9 times x equals -72, because -9 multiplied by the other factor that we are trying to solve for, which is x in this case, should equal -72. So then, to completely finish simplifying this equation, we need to divide -9 from both sides, so we can get our variable x, that we are trying to get the answer for, by itself. Then finally, you get x equal to 8, as our final, simplified answer. These are all of the steps to completely get the correct answer to your question.

Hope this helps!!!
