c

Step-by-step explanation:

Step-by-step explanation:

Cuz sides of square are same, we just find hypotenusa side of triangle (use Phytagoras Theorem) :

c² = a² + b²

c² = 2² + 4²

c² = 4 + 16

c² = 20

c = √20

Side of square is √20 units.

The area of square :

A = s²

= √20²

= √20 × √20

= 20 units²

So, the area of square is 20 units²

Step-by-step explanation:

Answer:

2nd choice: x = -2 or x= 3/5

Step-by-step explanation:

5x² + 7x = 6

We can solve.

5xx + 7x - 6 = 0

try the diamond method first

-30 = 5*-6....   -3*10 = -30  and  -3x + 10x = 7x

So...

5xx - 3x  + 10x  - 6 = 0

x(5x - 3) + 2(5x - 3)  = 0

(x +2)(5x - 3) = 0

roots  x = -2  and x = +3/5

Answer:

The correct answer is x=-2 or x=3/5. I found this answer by using an app called Photomath, you should download it. it really helped me :)

you plug -1 into the equation y=2x+5 for x since that is what x is equal to and then solve it so y= -3 then your coordinates would be (1,-3)

Answer:

a. 43.96 feet

b.153.86 square feet

Step-by-step explanation:

Hi, the path through the middle of the circular garden is the diameter.

Since the diameter is equal to:

Diameter = 2 radius (r)

Solving for r

14 =2r

14/2 = r

r = 7 feet

The distance around the outside of this garden is the perimeter.

Perimeter of a circle (P) = 2 π r

Replacing with the values given:

P = 2 (3.14) 7 = 43.96 feet

b. area of the circle-

Area of a circle (A)= π r²

Replacing with the values given:

A = 3.14 (7²) =153.86 square feet

What two numbers multiply to 32 and add to -12

-8*-4 = 32

-8-4 = -12

(x-8) (x-4)

Answer:

(x - 4)

Step-by-step explanation:

Answer:

(-b) (4a-b)

Step-by-step explanation:

(2a – b)^2- 4a^2

Let m = 2a-b

m^2 - (2a)^2

We know this is the difference of squares

x^2 - y^2 = (x-y)(x+y)

(m-2a) (m+2a)

Replace m with 2a -b

(2a -b-2a) (2a-b+2a)

Simplify

(-b) (4a-b)

Answer:

(4a - b)(-b)

Step-by-step explanation:

If we let x = 2a - b and y = 2a, our expression now looks like

[tex]x^2-y^2[/tex]

This kind of a expression is a common pattern in algebra called a difference of squares, and it can be factored like this (for a visual proof, see the attached image, courtesy of Great Maths Teaching Ideas):

[tex]x^2-y^2=(x+y)(x-y)[/tex]

Replacing x and y with 2a -b and 2a, our expression now becomes

[tex][(2a-b)+2a][(2a-b)-2a]\\=(2a-b+2a)(2a-b-2a)\\=(4a-b)(-b)[/tex]

So in factored form,

[tex](2a-b)^2-4a^2=(4a-b)(-b)[/tex]

Answer:

15/-7

Step-by-step explanation:

slope is y(2) - y(1) / x(2) - x(1)

120-0/0-56

120/-56

simplified

The slope from point A to point B is found by dividing the rise by the run. With a rise of -120 and a run of 56, the slope is approximately -2.14, indicating a downward slope from A to B.

To find the slope from point A to point B, we can use the formula slope = rise/run. In this scenario, point A is at (0, 120) and point B is at (56, 0).

First, determine the rise, which is the change in the y-coordinates (vertical change). The rise is 0 - 120 = -120.

Next, determine the run, which is the change in the x-coordinates (horizontal change). The run is 56 - 0 = 56.

Now, we can calculate the slope: slope = rise/run = -120/56 = -2.14

Answer:

compounded quaterly

Step-by-step explanation:

hope this helps

plzz mark me brainliest

Answer:

Let's say:

AM = current amount of money = 3000

APR = interest rate  = 2.25

n = number of compounding periods

t = 5 years

Final amount of money:

FAM = AM x [1 + 2.25/n]^(n x 5) = 3000 x [1 + 2.25/n]^(n x 5)

Annual Compounding: FAM = 3000 x (1 + (2.25% / 1))^(1 x 5) = 3353.03

Quarterly Compounding: FAM = 3000 x (1 + (2.25% / 4))^(4 x 5) = 3356.16

Monthly Compounding: FAM = 3000 x (1 + (2.25% / 12))^(12 x 5) = 3356.86

Continuous Compounding: FAM = 3000 x 2.7183^(2.25% x 5) = 3357.22

=>Continuous Compounding gives largest benefit.

=> Option C is correct

Hope this helps!

-f +2+4f = 8-3f

3f+2 = 8-3f

6f = 6

f = 1

Answer:

f = 1

Step-by-step explanation:

Isolate the variable, f. Note the equal sign, what you do to one side, you do to the other.

Add 3f and subtract 2 from both sides:

-f + 2 (-2) + 4f (+3f) = 8 (-2) - 3f (+3f)

-f + 4f + 3f = 8 - 2

Simplify:

(-f + 7f) = 6

7f - f = 6

6f = 6

Isolate the variable, f. Divide 6 from both sides:

(6f)/6 = (6)/6

f = 6/6

f = 1

1 is your answer for f.

Jenny was at bat 250 times.

The percentage refers to a number that is out of 100. When describing components of a whole in mathematics, percentages are employed similarly to fractions and decimals. When employing percentages, the idea is that there are 100 equal pieces that make up the whole. In addition, the sign "%" is used to indicate that a number is a percentage. In stores, online, in commercials, and in the media, percentages are nearly always present. A crucial talent that may help you save time and money and raise your employability is the ability to comprehend what percentages represent.

Given jenny hit 32% of the time when she was at bat and also she had 80 hits. let's assume she had a total of x hits. so 32% of x will be equal to 80.

From that,

32% x = 80

32*x = 80 * 100

x = 250

Hence, Last season ball jenny was at bat 250 times.

To solve the inequality -0.2x+1.2<1.1, we subtract 1.2 from both sides and then divide by -0.2, which flips the inequality, resulting in x > 0.5.

To solve the inequality [tex]\frac{1.2}{-0.2x+1.2} < 1.1[/tex], we can follow a step-by-step process. First, we isolate the variable on one side. We'll subtract 1.2 from both sides of the inequality:

-0.2x+1.2-1.2 < 1.1-1.2

-0.2x < -0.1

Then we divide both sides by -0.2, remembering that dividing by a negative number will flip the inequality sign:

[tex]x > \frac{0.1}{0.2}[/tex]

x > 0.5

This means that for the inequality to hold true, x must be greater than 0.5. It's also important to note that by understanding the properties of inequalities and the operations performed on them, we can easily solve these mathematical statements.

The required probability of Sarah picking a blue marble on 2 consecutive draws without replacement is 15.8%. Option A is correct.

Probability can be defined as the ratio of favorable outcomes to the total number of events.

Here,
Total marbles [sample space] = 100
Total favorable outcome = 40 = 40%
Now,
Picking another blues marble,
Total marble becomes 99 and the total favorable outcome becomes 39,
Probability of picking marble in two consecutive drawn,
= 40/100 × 39 / 99
= 0.158
= 15.8%

Thus, the required probability of Sarah picking a blue marble on 2 consecutive draws without replacement is 15.8%. Option A is correct.

Answer:95units2

Step-by-step explanation:

1/2x7x5+5x5=95

Answer:

Step-by-step explanation:

hello :

here is an solution :

Answer:

f(3) =16

Step-by-step explanation:

f(x) = 3x + 7

Let x= 3

f(3) = 3*3 +7

     = 9+7

      = 16

Answer: 16

Step-by-step explanation: f(x) = 3x + 7 means that if we put an x into our function, a 3x + 7 comes out.

So if we want to find f(3), we're putting a 3 into our function which means that a 3(3) + 7 comes out which simplifies to 9 + 7 or 16.

So f(3) = 16 or the value of the function at 3 equals 16.

For the inequality t < -1, the numbers that are solutions to this inequality are -2, -3, and -10, as they are all less than -1.\

The inequality in question is t < -1, which indicates that the temperature (t) is colder than -1 degrees Fahrenheit. On a number line from -2 to +2, the numbers that satisfy this inequality would be all the numbers that are less than -1. Therefore, the solutions to the inequality would be the numbers that are to the left of -1 on the number line.

-2

-3

-10

The numbers 0, 1, and -1 do not satisfy the inequality because they are not less than -1.

It may be wrong :(
