Answer:

100 minutes

Step-by-step explanation:

Given data

Total distaance= 400meters

Speed= 4m/s

We know that the expression for speed is

Speed= distance/time

substitute to find time

4= 400/time

time= 400/4

time= 100 minutes

Answer:

slope is undefined

Answer:

true

Step-by-step explanation:

Let us calculate the determinant of this quadratic equation:

Δ = b^2 - 4ac = 16-4*(-1)*(-4) = 0

The equation has one solution

x = -b/2a = 2

Answer: 6??

Step-by-step explanation: Cause they are right next to each other and if u want me to be more specific its 6 units down :)

Answer:

The distance will be √(x2-x1)^2+(y2-y1)^2

=√(5-5)^2+(10-4)^2

=√(0)^2+(6)^2

=√(6)^2

=6 units

Answer:

Step-by-step explanation:

First, carry out the indicated multiplication.  We get:

2m/5 - 4/5 + 3/5, which condenses to

                        2m - 1

2m/5- 1/5 or ---------------

                              5

Answer:

1.x=15

2.<A=29

Step-by-step explanation:

(2x-1)+(3x+9)+(6x+7)=180

2x-1+3x+9+6x+7=180

11x+15=180

11x=180-15

11x=165

x=165/11

x=15

2.<A=2x-1

  <A=2*15-1

  <A=30-1

  <A=29

Answer: (x + 3)^2 + (y - 4)^2 = 49

Step-by-step explanation:

The equation of a circle given the center and radius: (x - h)^2 + (y - k)^2 = r^2

Given: center (-3,4) ; h = -3 and k = 4

diameter = 14

To find the radius: divide the diameter by 2 = 14/2 = 7 = r

Center: (-3,4) and radius: 7

Equation of a circle: (x - h)^2 + (y - k) ^2 = r^2

Substitute h = -3, k = 4, r = 7

(x - (-3))^2 + (y - 4)^2 = 7^2

Answer:

Equation of the circle: (x + 3)^2 + (y - 4)^2 = 49

Step-by-step explanation:

A) Discriminant = b² - 4ac = (12)² - 4(9)(4) = 144 - 144 = 0

B) Since the discriminant is 0, this means the equation only has one root.

C) The root is real in this case since the discriminant is not negative. Otherwise, we would have two imaginary roots if it were (remember that complex roots come in pairs)

Answer:

13,564.8

Step-by-step explanation:

The ratio of the volumes of similar solids is the cube of the scale factor.

Scale factor:

red solid : blue solid = 12/10 = 6/5

Ratio of volumes:

volume red solid : volume blue solid = (6/5)^3

volume of red solid = 7850 ft^3 * (6/5)^3 = 13,564.8 ft^3

Answer: V = 13,564.8 ft^3

Answer:

The number must be bigger than 7 for the equation be true

If you put x= 7 or x= 6...it will not be true

Step-by-step explanation:

x+7< 2x

7< x

x> 7

Example x=9          

9+7 < 2x9

16< 18  TRUE

The equation is x + 7 = 4 - 2x. Then the solution of the equation will be negative 1.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

A number increased by 7 is 4 less than twice the number.

Let the number be 'x'. Then the inequality is given as,

x + 7 = 4 - 2x

Simplify the equation, then we have

x + 7 = 4 - 2x

x + 2x = 4 - 7

3x = - 3

x = -3/3

x = -1

The equation is x + 7 = 4 - 2x. Then the solution of the equation will be negative 1.

Answer:

$18,000

Step-by-step explanation:

Difference in the years is 192000-156000= 36000

To find rate of change, divide the difference by amount of years in difference.

36000/2017-2015

36000/2

Hence, $18000 per year

Answer:

3.25 years

Step-by-step explanation:

The computation of the number of years is shown below:

Given that

PV = $225,000

RATE = 8%

PMT = $0

FV = $175,204.80

The formula is shown below:

= NPER(RATE;PMT;PV;FV;TYPE)

After applying the above formula, the number of years would be 3.25 years

The exponent function of the graph will be W.  Then the correct option is D.

Let b is the base and x is the power of the exponent function and a is the leading coefficient. The exponent is given as

y = a(b)ˣ + c

Where c is the intercept.

Let the leading coefficient will be 1.

Then the equation will be

y = (b)ˣ + c

The exponent function has a y-intercept at (0, 3).

Then the exponent function is given as,

y = (b)ˣ + 2
