Given: ABCD is a rectangle. If AC = 10, then BD = 5 8 10

Answer:

B) 2328.50

Step-by-step explanation:

We are given 200 shares at $11.58 per share. By multiplying the number 200 with each share value will get the cost of all shares.

Total shares = 200

Cost per share = $11.58

Cost of 200 shares: Total shares * cost per share

= 200 * 11.58 = 2316

Commission charged = $12.50

Total amount: Cost of 200 shares + Commission charged

                      = 2316 + 12.50

Total amount = 2328.50

Answer:

Option B.

Step-by-step explanation:

The given graph is of a line which is parallel to the x axis.

Let the equation of the line is y = mx + c

where m is the slope and c is a constant representing y - intercept.

Since the graphed line is parallel to x = 0

So for the values of x = 0 equation of the line will be

y = c (constant)

Therefore, Option B. Linear constant is the answer.

Answer:

If it was 750,000 liters it would be 750 liters

Step-by-step explanation:

Bill can solve this by first thinking that 1 liter is 1,000 milliliters. Then 1,000 times 750 equals 750,000. Then he would do 750 times 1 and get 750. Bill would then realize that  750,000 milliliters is equal to 750 liters

Answer:

The value not permissible for a is -3.

Step-by-step explanation:

Considering real numbers, the expression is undefined for any value a for which the denominator expression is zero.

[tex]\frac{a^2}{2a+6}, \,\,\,2a+6\neq 0\implies a\neq -3[/tex]

The expression is valid for all real numbers, except -3.

Answer:

a≠-3

Step-by-step explanation:

We cannot divide by zero, so the denominator cannot be zero

2a+6≠ 0

Subtract 6 from each side

2a+6-6≠ 0-6

2a ≠-6

Divide each side by 2

2a/2 ≠-6/2

a≠-3

5 - 4 + 7x + 1 = 7x + (5 - 4 + 1) = 7x + 2

NO SOLUTIONS:

5 - 4 + 7x + 1 = 7x + a    (a - any real number, except 2)

ONE SOLUTION:

5 - 4 + 7x + 1 = bx + c     (b - any real number, except 7, c - any real number)

INFINITELY MANY SOLUTIONS:

5 - 4 + 7x + 1 = 7x + 2

Examples:

2x + 3 = 2x + 5     subtract 2x from both sides

3 = 5    FALSE      (NO SOLUTIONS)

2x + 3 = x - 4      subtract x from both sides

x + 3 = -4       subtract 3 from both sides

x = -7          (ONE SOLUTION)

2x + 3 = 2x + 3      subtract 2x from both sides

3 = 3     TRUE      (INFINITELY MANY SOLUTIONS)

1) For No Solution

5 - 4 + 7x +1 = 7x

2) For One Solution

5- 4 +7x + 1 = 3

3) For No Solution

5 - 4 + 7x + 1 = 7x + 2

Answer:

The correct answer option is C. y<= -4x + 25.

Step-by-step explanation:

Firstly, we will find out the equation of the line with the help of using two points (0, 25) and (-6, 49).

The slope (m) = [tex]\frac{49-25}{-6-0} =-4[/tex].

We know the standard form of the equation is [tex]y=mx+c[/tex] so the y-intercept (c) can be found by putting in the values of the slope and the coordinates of a point.

[tex]25=-4(0)+c\\\\c=25[/tex]

Therefore, the equation of the line is y = -4x + 25.

Now since the inequality is dealing with the value of y and we know that the values of y go vertically (up and down). So if we look at the graph, the shaded area includes the smaller values of y and the line is a solid one.

Therefore, the inequality will be y<= -4x + 25.

If you don't understand it this way, you can pick up a point and test the inequality.

Taking the easiest point (0, 0) to check.

0 <= -4 (0) + 25

0 <= 25 --- True

Answer:

f(-3) =10

Step-by-step explanation:

When given a function f(-3), they want you to substitute x=-3 into the function f(x) and solve

f(x) =|2x+1|+5

Let x=-3

f(-3) =|2 *-3+1|+5

f(-3)=|-6+1|+5

f(-3)=|-5|+5

The absolute value of -5 is positive 5  (absolute values means always positive).

f(-3)=5+5

The gradient of the line y= 5-5x is -5 which is the coefficient of 'x'. This connotes a negative slope, meaning the line descends as we move along the positive x-axis.

The equation y = 5 - 5x represents a straight line in the xy-plane. The coefficient of 'x' in the equation represents the slope of the line. Therefore, the gradient of the line is -5. This means for every unit increase in x, y will decrease by 5 units. This negative slope suggests that the line moves downwards as the x-value increases, similar to our reference figure A1 where the slope caused a rise or fall on the vertical axis for every increase of 1 on the horizontal axis.

Answer: 0.4 miles

Step-by-step explanation:

You can use the equation y=1/5x to help you figure it out where x is the days and y is the length. y=1/5(2). y=2/5 or 0.4 miles. Please vote my answer as brainliest

The road construction crew would pave 2/5 of a mile in 2 days, as they pave 1/5 mile every day.

The road construction crew paves 1/5 mile each day. If they were to work for 2 days, to find out how much they would pave, you would simply multiply the pace per day by the number of days. So, 1/5 mile * 2 days = 2/5 miles. Therefore, the crew would pave 2/5 of a mile in 2 days.

To find out how much the road construction crew would pave in 2 days, we need to multiply the amount they pave in 1 day by 2. So, if they pave 1/5 mile every day, they would pave 1/5 * 2 = 2/5 mile in 2 days.

Answer:

The difference in temperature between a depth of 1200 meters and 3750 meters is 2.55

Step-by-step explanation:

The temperature T of the water in an ocean at depth X below 900 meters is given by:

T= 4500/X

To calculate the difference between a depth of 1200 meters and 3750 meters, it is necessary to calculate the temperature individually.

first, 1200 meters and 3750 meters are below 900 meters, so the equation describe before is applicable.

As a result, for 1200 meters, the temperature (symbolized as T1) is given by:

T1=4500/X

T1=4500/1200

T1=3.75

For 900 meters, the temperature (simbolized as T2) is given by:

T2=4500/X

T2=4500/3750

T2=1.2

The difference between the temperature T1 and T2 is:

Difference in temperature = T1 - T2

Difference in temperature = 3.75 - 1.2

Difference in temperature = 2.55

So, the difference in temperature between a depth of 1200 meters and 3750 meters is 2.55

Answer:

6x^2 - 4y^2 + 2x^2 + 6xy

Step-by-step explanation:

Each of the adjacent sides of the rectangle has a congruent, opposite sides. The perimeter is the sum of the lengths of the 4 sides.

P = 2(3x^2 - 2y^2) + 2(x^2 + 3xy)

P = 6x^2 - 4y^2 + 2x^2 + 6xy

24.

The perimeter of a rectangle l × w is P = 2l + 2w.

We have l = 3x² - 2y² and w = x² + 3xy. Substitute:

P = 2(3x² - 2y²) + 2(x² + 3xy)      use distributive property

P = (2)(3x²) + (2)(-2y²) + (2)(x²) + (2)(3xy)

P = 6x² - 4y² + 2x² + 6xy      combine like terms

Jake reaches the top of the escalator because he exceeds the height of the escalator if he travels at the rate of 8.33 inches/second.

Unit rate is the ratio of two different units, with denominator as 1. For example, kilometer/hour, meter/sec, miles/hour, salary/month, etc. Arithmetic is probably the most basic and ancient branch of mathematics and is quite commonly used in our day-to-day life.

Given here: Jake reaches 25 inches above the ground in 3 seconds.

The unit rate of Jake's ascend is = 25/3

                                                =8.33 inches/second

If Jake rides the escalator for 15 seconds then we would climb

=8.33×15

=124.95 inches

After 45 seconds Jake would have climbed =45×8.33

                                                                          =374.85 inches

Thus after 45 seconds Jake reaches the top of the escalator.

Hence, Jake reaches the top of the escalator because he exceeds the height of the escalator if he travels at the rate of 8.33 inches/second.

Y-intercept.

By calculating the separations between two perpendicular lines that pass through a fixed point in Cartesian coordinates, we may find the location of a point P. Assume that O is the fixed point known as the origin and that XOX' and YOY' are the two perpendicular lines that pass through O and are referred to as the Cartesian or Rectangular co-ordinate axes.

given, the graph crosses the y-axis A point having an x-value and a y-value, is a coordinate: (x, y). The origin is the place where the two number lines converge, and it has the following coordinates: (0, 0). The x-value is zero when the graph of a function crosses the y-axis at a value b. As a result, the point is the y-intercept (0, b).
