PLEASE ANSWER THIS QUESTION RIGHT AND THE ANSWER CHOICES ARE IN THE ORDER.Which is the standard form of a quadratic equation?

Answer:

A = 832 m²

Step-by-step explanation:

using the formula of a regular polygon with,

n = number of sides

s = Side length

a = apothem

Area = ½ × ans

Where n = 10, a = 16 and s = 10.4

A = ½ × 16 × 10 × 10.4

A = ½ × 1664

A = 832 m²

Answer:

area = 832 m²

Step-by-step explanation:

the area (A) is calculated as

A = \(\frac{1}{2}\) pa ( p is the perimeter and a the apothem )

a decagon has 10 sides , then

p = 10 × 10.4 = 104 m

A = \(\frac{1}{2}\) × 104 × 16 = 52 × 16 = 832 m²

Answer:

\(2 \times 5 = 10 \\ 3 \times 11 = 33 \\ 10 + 33 = 43 \\ 43 {m}^{2} \)

Answer:

x=8y+120

Step-by-step explanation:

The required average mark for a one-hour exam is given as 81, as per the given condition.  

The average of the values is the ratio of the total sum of values to the number of values.

To find the student's grade, we need to calculate the average of all the exams. The total number of 1-hour exams is 4 + 2 = 6, so the total number of hours of exams is 6 * 1 hour = 6 hours.

First, we find the average of the four 1-hour exams: (63 + 78 + 95 + 90) ÷ 4 = 316 ÷ 4 = 79.

Next, we add the final exam grade, which counts as two 1-hour exams, to find the total number of exam points: 79 * 4 + 85 * 2 = 316 + 170 = 486.

Finally, we divide the total number of points by the total number of hours of exams to find the average exam grade: 486 ÷ 6 = 81.

So, the student's average exam grade is 81.

Bryan invested $1600 in the first account (earning 11% interest) and $4900 (6500 - 1600) in the second account (earning 7% interest).

Let's assume that Bryan invested an amount of x dollars in the first account, which earns 11% interest, and (6500 - x) dollars in the second account, which earns 7% interest.

The interest earned from the first account can be calculated as 0.11x, and the interest earned from the second account can be calculated as 0.07(6500 - x).

According to the problem, the total interest earned after one year is $519. So we can set up the equation:

0.11x + 0.07(6500 - x) = 519

Simplifying the equation:

0.11x + 455 - 0.07x = 519

0.04x + 455 = 519

0.04x = 64

x = 64 / 0.04

x = 1600

Therefore, Bryan invested $1600 in the first account (earning 11% interest) and $4900 (6500 - 1600) in the second account (earning 7% interest).

The new coordinate (- 7, 3 ) of the image of (-3,-7) under a rotation of 90 degrees.

A graph can be defined as a pictorial representation or a diagram that represents data or values.

Let the coordinate Z is (-3, -7)

Under a clockwise rotation about the origin of  90 degrees

A coordinate ( x, y ) → ( y, - x ),

The coordinate Z is (-3, -7) and is translated using the rule

Then simply plug in the values of x and y which are x = -3 and y = -7

Answer:

78.5

Step-by-step explanation:

We have the perimeter of the square, which is 40, and 40/4=10. In this picture, we see that the circle's diameter is the same as the length of one side of the square. Therefore, the diameter of the circle is 10. The are formula for circles is \(\pi r^{2}\), where \(r\) is the radius. The radius of the circle is just the diameter divided by 2, and 10/2=5. Now, \(5^2\) is 25, and \(3.14\cdot25=78.5\).

Step-by-step explanation:

a. The answer is: The fewest number of multibase blocks required to represent 20 longs in base seven is 2 flats.

b. The answer is: The fewest number of multibase blocks required to represent 10 longs in base three is 3 flats and 1 unit.

a. To represent 20 longs in base seven, we need to find the fewest number of multibase blocks required.

In base seven, we have the following conversions:

1 long = 1 unit

1 flat = 10 units

1 block = 10 flats

To represent 20 longs, we can use 2 flats (each flat representing 10 units) and 0 units since there are no remaining units.

So, the fewest number of multibase blocks required would be 2 flats.

Therefore, the answer is: The fewest number of multibase blocks required to represent 20 longs in base seven is 2 flats.

b. To represent 10 longs in base three, we need to find the fewest number of multibase blocks required.

In base three, we have the following conversions:

1 long = 1 unit

1 flat = 3 units

1 block = 3 flats

To represent 10 longs, we can use 3 flats (each flat representing 3 units) and 1 unit since there is one remaining unit.

So, the fewest number of multibase blocks required would be 3 flats and 1 unit.

Therefore, the answer is: The fewest number of multibase blocks required to represent 10 longs in base three is 3 flats and 1 unit.

A scale is a term that can be referred to as the representative fraction that compares the original length and image length of a given object. Types of scale include enlarged scale, reduced scale, and real scale.

Scale can be expressed as;

Scale = \(\frac{length on drawing}{original length}\)

Thus a scale has no unit.

Answer:

1000 yards

Step-by-step explanation:

First, create a triangle using the two known amounts.

12 blocks east will act as your base and 16 blocks south as your height. Connect these two lines to form a triangle.

This becomes a matter of the Pythagorean theorem or A^2 + B^2 = C^2

A= 12

B= 16

12^2 + 16^2 = C^2

400 = C^2

C= 20 blocks

Multiply this number by 50 to get the number in yards.

20 * 50 = 1000 yards

As my previous answer got deleted for being wrong (in which it was right), I will answer again.

The answer is 1. Why? Just plug it into the equation. F(1) = 2(1) + 5 = 7.

This is proof that it is right, and that there are some corrupt admins on brainly.

How to get to this solution?

Well notice how we are given what f(a) is. It is 2a + 5. So plug this in for f(a).

If we do so, we get 2a + 5 = 7.

Solving this equation, we get a = 1.

The equation is rewritten in slope-intercept form as y = -3x + 5.

Slope = -3; y-intercept = 5.

The equation of any given line, when written in the slope-intercept form is expressed as y = mx + b, where:

Given the equation in standard form as 6x + 2y = 10, rewrite the equation in slope-intercept form as explained in the steps below:

6x + 2y = 10

2y = -6x + 10 [subtraction property of equality]

Divide both sides by 2

2y/2 = -6x/2 + 10/2

y = -3x + 5

The equation is y = -3x + 5, Destinee didn't rewrite the equation correctly because he subtracted 2y from both sides rather.

The slope of y = -3x + 5 is -3.

The y-intercept of the equation is 5.

Case 1: a = 0; b = 0 --> Real Number

Case 2: a = 0; b ≠ 0 --> Non-Real Complex Number

Case 3: a ≠ 0; b = 0 --> Real Number

Case 4: a ≠ 0; b ≠ 0 --> Non-Real Complex Number

For each case, we can determine whether the expression a + bi represents a real number or a non-real complex number based on the values of a and b.

Case 1: a = 0; b = 0

In this case, both a and b are zero. The expression a + bi simplifies to 0 + 0i, which is equal to 0. Therefore, the expression represents a real number.

Case 2: a = 0; b ≠ 0

Here, a is zero, but b is nonzero. The expression a + bi becomes 0 + bi, where b is a nonzero real number multiplied by the imaginary unit i. Since the expression contains a nonzero imaginary part, it represents a non-real complex number.

Case 3: a ≠ 0; b = 0

In this case, a is nonzero, but b is zero. The expression a + bi simplifies to a + 0i, which is equal to a. As there is no imaginary part in the expression, it represents a real number.

Case 4: a ≠ 0; b ≠ 0

Here, both a and b are nonzero. The expression a + bi contains both a real part (a) and an imaginary part (bi). Thus, it represents a non-real complex number.
