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:

1 square unit

Step-by-step explanation:

Plug in s = 1/4 into the formula.

A = 16(1/4)^2

= 16(1/16) (since 4^2=16)

= 1 (cancel out the 16s)

The required perimeter of the given shape is given as 14π.

Given that,
To determine the perimeter of the given shape,

Perimeter is the measure of the figure on its circumference.

Here,
The perimeter of the semi-circle is given as πr.
Since there are 4 sub circles, with a radius of 6, 4, 3, and 1 unit
The perimeter of the circles is given as = 6π + 4π + 3π + π = 14π

Thus, the required perimeter of the given shape is given as 14π units.

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

Answer:

Greater than.

Step-by-step explanation:

Let the original value be x.

A 50% increase in x is given by

x + 50%x

=> x + 0.5x

=> 1.5x

Followed by a 33 [tex]\frac{1}{3}[/tex] % decrease in the value gives:

1.5x - 33 [tex]\frac{1}{3}[/tex] %(1.5x)

=> 1.5x - 0.33(1.5x)

=> 1.5x - 0.495x

=> 1.005x

Since 1.005x is greater than the original value, x, then:

A 50% increase followed by a 33 [tex]\frac{1}{3}[/tex] % decrease gives a value that is greater than the original.

Pythagorean Theorem

The Pythagorean Theorem, also known as Pythagoras' theorem, is a fundamental relation between the three sides of a right triangle. Given a right triangle, which is a triangle in which one of the angles is 90°, the Pythagorean theorem states that the area of the square formed by the longest side of the right triangle (the hypotenuse) is equal to the sum of the area of the squares formed by the other two sides of the right triangle:

In other words, given that the longest side c = the hypotenuse, and a and b = the other sides of the triangle:

a2 + b2 = c2

This is known as the Pythagorean equation, named after the ancient Greek thinker Pythagoras. This relationship is useful because if two sides of a right triangle are known, the Pythagorean theorem can be used to determine the length of the third side. Referencing the above diagram, if

a = 3 and b = 4

the length of c can be determined as:

c = √a2 + b2 = √32+42 = √25 = 5

It follows that the length of a and b can also be determined if the lengths of the other two sides are known using the following relationships:

a = √c2 - b2

b = √c2 - a2

The law of cosines is a generalization of the Pythagorean theorem that can be used to determine the length of any side of a triangle if the lengths and angles of the other two sides of the triangle are known. If the angle between the other sides is a right angle, the law of cosines reduces to the Pythagorean equation.

There are a multitude of proofs for the Pythagorean theorem, possibly even the greatest number of any mathematical theorem.

Algebraic proof:

In the figure above, there are two orientations of copies of right triangles used to form a smaller and larger square, labeled i and ii, that depict two algebraic proofs of the Pythagorean theorem.

In the first one, i, the four copies of the same triangle are arranged around a square with sides c. This results in the formation of a larger square with sides of length b + a, and area of (b + a)2. The sum of the area of these four triangles and the smaller square must equal the area of the larger square such that:

(b + a)2 = c2 + 4  

ab

2

= c2 + 2ab

which yields:

c2 = (b + a)2 - 2ab

= b2 + 2ab + a2 - 2ab

= a2 + b2

which is the Pythagorean equation.

In the second orientation shown in the figure, ii, the four copies of the same triangle are arranged such that they form an enclosed square with sides of length b - a, and area (b - a)2. The four triangles with area ab  2 also form a larger square with sides of length c. The area of the larger square must then equal the sum of the areas of the four triangles and the smaller square such that:

(b - a)2 + 4  

ab

2

=

(b - a)2 + 2ab

= b2 - 2ab + a2 + 2ab

= a2 + b2

Since the larger square has sides c and area c2, the above can be rewritten as:

c2 = a2 + b2

which is again, the Pythagorean equation.

There are numerous other proofs ranging from algebraic and geometric proofs to proofs using differentials, but the above are two of the simplest versions.

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

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.

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

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.
