Answer:

A, C

Step-by-step explanation:

Quadratic formula:

\(x = \frac{ - b± \sqrt{b^{2} - 4ac } }{2a} \)

a is the coefficient of x², b is the coefficient of x and c is the constant when a second degree polynomial is equal to zero. (ax² +bx +c= 0)

x² +5x +11= 0

a= 1, b= 5, c=11

Thus, using the quadratic formula:

\(x = \frac{ - 5± \sqrt{ {5}^{2} - 4(1)(11)} }{2(1)} \\ x = \frac{ - 5± \sqrt{25 - 44} }{2} \\ x = \frac{ - 5± \sqrt{ - 19} }{2} \)

∴The answers are A and C.

Answer:

  A

Step-by-step explanation:

Reflection across a line reverses the orientation of the figure from CW to CCW, or vice versa. Each point on the image is the same distance from the line of reflection as the corresponding point on the preimage.

These characteristics are manifested in figure A.

__

Figure B represents a translation to the right; Figure C represents both rotation and translation. Figure D is translation up and to the right.

_____

Additional comment

When vertices of a figure are labeled, their orientation (CW or CCW) is easy to identify. When they are not, it isn't always easy. It helps when the figure has no particular symmetry, as here. We can, for example, consider the sides in order from shortest to longest. That would make the orientation CCW on the left of figure A, and CW on the right. Figure A is the only figure in which the orientation changes.

  CW=clockwise; CCW=counterclockwise

The speed of the boat in still water (x) is 12 mph, and the speed of the current (y) is 9 mph.

To find the speed of the boat in still water and the speed of the current, let's follow these steps:

Step 1: Let x represent the speed of the boat in still water, and y represent the speed of the current. The speed downstream is (x + y) and the speed upstream is (x - y).

Step 2: Use the formula distance = time × speed to write two equations based on the given information.

Downstream: 9(x + y) = 189

Upstream: 63(x - y) = 189

Step 3: Simplify both equations:

Downstream: x + y = 21 (divide both sides by 9)

Upstream: x - y = 3 (divide both sides by 63)

Step 4: Solve the system of equations by adding the two simplified equations:

2x = 24

x = 12

Step 5: Plug the value of x back into either equation to solve for y:

12 + y = 21

y = 9

So, the speed of the boat in still water (x) is 12 mph, and the speed of the current (y) is 9 mph.

Answer:

\(49x^2-7^2=49(x-1)(x+1)\)

Step-by-step explanation:

Factoring

We need to recall this property of binomials:

\((a-b)(a+b)= a^2-b^2\)

It allows us to factor the difference between two squares as follows.

\(a^2-b^2=(a-b)(a+b)\)

The given expression is

\(49x^2-7^2\)

Comparing with the above expression:

\(a^2=49x^2\)

Taking square root:

\(a = 7x\)

\(b^2=7^2\)

Taking square root:

b=7

Factoring:

\(49x^2-7^2=(7x-7)(7x+7)\)

Now we can see each factor can be taken out the common factor 7:

\(49x^2-7^2=7(x-1)*7(x+1)\)

Multiplying:

\(\boxed{49x^2-7^2=49(x-1)(x+1)}\)

Answer: 24 people earnt As

Step-by-step explanation:

1. We know that 18 people are the other 3/7 of the class

2. We first find out 1/7, which is calculated by dividing 3/7 by 3, which is 18 / 3 so 6

3. We can then find 4/7 by multiplying the amount of 1/7 by 4, so 6 x 4 = 24

on solving the equation, we have therefore the value of x from the given equation comes out to be 13.5

An equation is a formula in mathematics that joins two statements with the equal symbol = to represent equality. The definition of an equation in algebra is a mathematical statement proving the equality of two mathematical expressions. In the equation 3x + 5 = 14, for instance, the terms 3x + 5 and 14 are separated by an equal sign. The link between two phrases on either side of a letter is expressed mathematically. There is often only one variable, which is also the symbol. instance: 2x - 4 Equals 2.

Answer:

\(y=1.225\)

Step-by-step explanation:

\(24y+0.2=29.6\)

Subtract 0.2 from both sides:

\(24y+0.2-0.2=29.6-0.2\\24y=29.4\)

Divide both sides by 24:

\(\frac{24y}{24} =\frac{29.4}{24} \\y = 1.225\)

y = 1.225 is your final answer.

The amount $600 would be after 3 years at 8% interest compounded continuously is $755.83

Compound interest are amount of money added on amiunt invested.

Given the following parameters

P = $600
r = 8% = 0.08
t = 3 years

Using the compound interest formula

A(t) = Ao(1+r)^t

Okay, here we have this:

Considering the provided graph, we obtain the following:

Looking at the graph we can see that f(1)=4, and f(0)=1, so let's replace in the most common form of the equation (y=bˣ), to find "b":

b¹=4

b=4

So, according with this, finally we find that the equation of the exponential function whise graph is shown is y=4ˣ.

Answer:

Therefore, the total used car sales were $179,625.

Step-by-step explanation:

Let's assume that the ratio of new car sales to used car sales is 3x:5x, where x is a constant.

The total car sales were $287,400, which means the sum of the new car sales and used car sales is $287,400:

3x + 5x = 8x

So, the total sales can be expressed as:

8x = $287,400

To find the value of x, we need to divide both sides by 8:

x = $35,925

Now, we can calculate the used car sales by multiplying 5x by the value of x:

Used car sales = 5x * x = 5 * $35,925 = $179,625

Therefore, the total used car sales were $179,625.
