Answer:

  A.  d = 0 -- one (1) solution

  B.  x = {1, 3.5}

Step-by-step explanation:

A. The discriminant for ax²+bx+c = 0 is ...

  d = b² -4ac

For the given equation, this is ...

  d = (-36)² -4(9)(36) = 0

The discriminant is zero (0).

The discriminant divided by the leading coefficient (a=2) will give the difference between the two roots of the equation. When the difference is zero, as here, both roots are the same. Effectively, there is one (1) solution to the equation.

__

B. The equation can be factored as ...

  2x² -9x +7 = (2x -7)(x -1) = 0

The solutions are the values of x that make the factors be zero:

  2x -7 = 0  ⇒  x = 7/2

  x -1 = 0  ⇒  x = 1

  The solutions are x = 7/2  or  x = 1.

Answer:

The possible lengths of c are between 3 to 17.

Step-by-step explanation:

According to the scenario, calculation of the given data are as follows,

a = 7

b = 10

As we know that, in a triangle length of third side is always greater than difference between the given two side, and always lesser than sum of both side.

So, Difference between both side = 10 - 7 = 3

Sum of both side = 10 + 7 = 17

Hence, the possible lengths of c are between 3 to 17.

Answer:

22.2 cm

Step-by-step explanation:

First, find the area of the larger circle.

50.2 x 2.5 = 125.5

Now, we need to find the diameter of the larger circle. We have the area, so we can plug this value into the formula of the area of the circle to find the diameter.

A = pi • r^2

125.5 =3.14 •r^2

122.36 = r^2

r = 11.1

Since radius is half the diameter, multiply r by 2.

11.1 x 2 = 22.2 centimeters

Answer:

3 units

4 1/2 or - 1 1/2

Step-by-step explanation:

Given that :

Value of n is a distance of 3 units from 1 1/2 on a number line.

Recall that a number line may be divided into two parts that is the left and righmosr portions with 0 as the mid point.

Hence a value of 3 units from 1 1/2 may be to the right (positive) or to the left(negative side of the line).

Therefore :

1 1/2 + 3 = 4 1/ 2

1 1/2 - 3 = - 1 1/2

The value n will result in a distance of 3 units in either way and could be either 4 1/2 or - 1 1/2

Answer:

-248.15°C

Step-by-step explanation:

An object in a laboratory is cooled to 25 Kelvin. What is the temperature of the object in degrees Celsius?

The formula that converts from Kelvin to degrees Celsius =

Celsius = (Kelvin – 273.15)

Kelvin = 25K

Hence:

°C = 25 - 273.15

°C = -248.15°C

Therefore, the temperature of the object in degrees Celsius is -248.15°C

Answer:-248

Step-by-step explanation:

Answer:

The dependent variable = Number of homeruns

Independent variable = years played

The Independent variable is Number of characters per minute

Dependent variable is Texting speed

Step-by-step explanation:

The independent variable are the variables which are used to infer or being about changes to the dependent variable by supplying different values of them, they are also called predictor variables. By varying the number of years, a baseball players' number of homeruns' can be predicted in such basis, hence, the

predicted or dependent variable is the number of homeruns'.

Similarly, the Number of characters (independent) an individual is able to type within a particular period of time can be used determine the Texting speed (dependent) of such person.

I'm late I know but this might help someone else looking for the same answer.

The independent variable is- years played

dependent is- home runs

2.

independent- time

dependent- texting speed

Step-by-step explanation:

4.5 x 10.4 = 48.6 and that divided by 300 give u ur answer.

Hope this helps!

The value of the expression (4.5 x 10^4) divided by (300) is 150.

"It is an expression which is made up of variables, constants and some mathematical operations."

For given example,

We have been given an expression (4.5 x 10^4) divided by (300)

We need to find the value of given expression.

(4.5 x 10 ^4) divided by (300)

=  (4.5 × 10000)/300

= 45000/300

= 150

Therefore, the value of given expression (4.5 x 10^4) divided by (300) is 150.

Answer:

Quantity A because it changes with gravitational pull.

Explanation:

Mass defines the constitutive matter of an object. It is immutable (does not change). Although it could be converted into energy, the matter is constant.

On the other hand, the weight of an object (gravitational force) depends on the acceleration due to gravity.

That is why an astronaut weighs about three times more on earth than on Mars. The gravitational acceleration on Mars is about one third that on earth.

Answer:

y+2=.25(x+3)

Step-by-step explanation:

The point slope form is shown as follows

y-y₁=m(x-x₁)

We know that the slope (m) is equal to .25 and that x₁=-3 and y₁=-2

We can plug this in and get

y-(-2)=.25(x-(-3))

Simplify the signs to get

y+2=.25(x+3)

The answers for both the parts are a) 260 and b) 200 Jolly Rancher and 520 jawbreakers.

A ratio is a way to show a relationship or compare two numbers of the same kind. We use ratios to compare things of the same type.

Given that, a candy jar have candies type Jolly Rancher and jawbreakers

in ratio 5:13 respectively.

Let the number of Jolly Rancher and jawbreakers be 5k and 13k respectively,

a) When you have 100 Jolly Rancher, then,

5k = 100

k = 20

Hence, number of jawbreaker = 20×13 = 260

b) When the total number of candies in the jar is 720, then,

5k+13k = 720

18k = 720

k = 40

Therefore, number Jolly Rancher and jawbreakers it contains = 40×5 = 200 and 13×40 = 520

Hence, The answers for both the parts are a) 260 and b) 200 Jolly Rancher and 520 jawbreakers.

Answer: 1967

Step-by-step explanation:

Ada was 15 years when her sister Ngozi was 18 years.

This means that Ngozi is older than Ada by:

= 18 - 15

= 3 years

If Ngozi is older by 3 years, this means that she must have been born 3 years earlier than Ada

If Ada was born in 1970, Ngozi was born:

= 1970 - 3

= 1967
