Answer:

  y = -5x +13

Step-by-step explanation:

We know from the slope-intercept equation ...

  y = mx + b

that the y-intercept b can be found as ...

  b = y - mx

Filling in the given values of m and (x, y), we find ...

  b = -2 -(-5)(3) = 13

Then the equation is ...

  y = -5x +13

Answer: D

Step-by-step explanation:

Substitute values for x until they all work.

A. y = 2 x 2 + 5 = 9 fail

B. y = 2 x 2 - 6 = -2 fail

C. y = -2 x 2 - 5 = -9 fail

D. y = -0.5 x 2 - 5 = -6 ok

y = -0.5 x 5 - 5 = -7.5 ok

y = -0.5 x 6 - 5 = -8 ok

Answer:

113

Step-by-step explanation:

The volume of a sphere is [tex]\frac{4}{3}\pi r^3[/tex], where [tex]r[/tex] is the radius of the sphere. The radius of the given sphere is 3 ft, so its volume is [tex]\frac{4}{3} \pi \cdot 3^3 = 36\pi[/tex]. Using 3.14 for [tex]\pi[/tex], this is approximately equal to 113.04. Rounding to the nearest whole number, the answer is 113 cubic feet.

Answer: 113 (rounded)

Step-by-step explanation:

Hey!

So for this we just use our sphere formula and follow the steps.

Volume= 4/3 πr^3

R= radius (half of diameter)

For pi we are going to use 3.14.

Let’s work this out now.

Radius is 3 so since it is cubed, we multiply it by itself 3 times. We get 27. Now, let’s multiply this by 3.14 and get 84.78.

Lastly, multiply by 4/3. We get 112.9333. This is the volume.

Hope this helped! :D

Find the Inverse of a 3x3 Matrix.

First

Find the Determinant of A(The coefficients of e

Proceed towards finding the CO FACTOR of the 3x3 Matrix.

+. - +

A= [ 1 -1 -1 ]

[ -1 2 3 ]

[ 1 1 4 ]

The determinant of this is 1.

Find the co factor

After Evaluating The Determinant of each 2x 2 Matrix

You'll have

[ 5 7 -3]

[3 5 -2 ]

[-1 -2 1]

Reflect this along the diagonal( Keep 5,5 -2)

Then switching positions of other value

No need of Multiplying by the determinant because its value is 1 from calculation.

After this

Our Inverse Matrix Would be

[ 5 3 -1 ]

[7 5 -2 ]

[ -3 -2 1]

THIS IS OUR INVERSE.

Given:

A right angle triangle with angles 45, 45, 90 degrees.

Hypotenuse of the triangle = [tex]7\sqrt{2}[/tex] mm

Base of the triangle = t

To find:

The value of t.

Solution:

In a right angle triangle,

[tex]\cos \theta=\dfrac{Base}{Hypotenuse}[/tex]

Using this trigonometric ratio in the given triangle, we get

[tex]\cos (45^\circ)=\dfrac{t}{7\sqrt{2}}[/tex]

[tex]\dfrac{1}{\sqrt{2}}=\dfrac{t}{7\sqrt{2}}[/tex]

[tex]\dfrac{7\sqrt{2}}{\sqrt{2}}=t[/tex]

[tex]7=t[/tex]

Therefore, the value of t is 7 millimetres.

Answer:

The volume of a cube is the side length cubed.

V = s x s x s  where s is the length of the side = s x s^2 = 6s^2 so s must be 6.

The side length is 6 ,

Therefore the surface area is 6 times the area of each side = 6 x 6^2 = 6 x 36

Answer:

0.944

Step-by-step explanation:

First of all, are you sure the datas are alright? We have a count of 1054 defendants while adding up all these numbers.

Assuming the datas are true, out of the 1054 defendants:

- 399 are sent to prison and guilty

- 567+29 = 596 aren't sent to prison.

Since we are looking for the probability that a randomly selected defendant either pled guilty or was not sent in prison, it means we have

[tex] \frac{399+596}{1054} = \frac{995}{1054} = 0.944[/tex]

(rounded to three decimal places).

Answer:

Step-by-step explanation:

they both add up to 180 since they're both on line BI

Answer:

<EDH

Step-by-step explanation:

When two angles are supplementary they sum to 180. This means together they form a straight line. So, to find the answer find the angle that connects to <HDI to create one straight line. In this case, that is <EDH because line EI is straight and the two aforementioned angles are the ones that create the line.

Answer:

the rate at which the temperature drops

the day of the week

Step-by-step explanation:

Since we can choose the number of hour, it is dependent on us.

If we set time = 2, then it would 5 x 2 = 10 degree

Similarly, if we change time, the temperature changes. Thus, it is dependent.

Temperature is dropping at a rate of five degrees per hour.

If t = 1, T = 5*1 = 5°, rate = 5

if t = 2, T = 5*2 = 10°, rate = 5

if t = 3, T = 5*3 = 15°, rate = 5

Notice that rate doesnt change, even the temperature and time changes.

Thus, rate is independent.

There are six sides to a die and only one side has a two, so the probability of rolling a 2 is 1/6.

There are two sides to a coin and only one side has a head, so the probability of its coming up heads is 1/2.

The two events (rolling a die and flipping a coin) are independent, so the probability of both events occurring is (1/6)(1/2) = 1/12

Answer:

5/2

Step-by-step explanation:

cscθ = 1/sinθ = 1/(2/5) = 1 x (5/2) = 5/2

We know,

[tex] \boxed{sin( \theta) = \frac{1}{csc( \theta)} }[/tex]

So,

=》

[tex] \dfrac{2}{5} = \dfrac{1}{ \csc( \theta) } [/tex]

The perimeter of the considered isosceles triangle is  28.8 in. approx.

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

Considering the attached image below, which has same isosceles triangle with same measurements, we see that:

|AC| = |AB| (because perpendicular dropped leaves two congruent triangles in ABC, as ADC and ADB)

similarly, we have:

|BD| = |DC|

But |BC| = 6 =  |BD| + |DC|,

Thus, 6 = |BD| + |DC| = |BD| + |BD| =2|BD|

|BD| = 6/2 = 3 inches = |DC|

From Pythagoras theorem for triangle ADB, we get:

[tex]|AB|^2 = |AD|^2 + |BD|^2\\|AB|^2 = 11^2 + 3^2 = 121 + 9 = 130\\|AB| = \sqrt{130} \approx 11.4 \: \rm in. = |AC|[/tex]

(positive square root since |AB| is length, which is a non-negative measure).

Thus, we get:

Perimeter of the rectangle = |AB| + |BC| + |AC| ≈ 11.4 + 6 + 11.4 = 28.8 in.
