Which ordered pair is a solution of the equation y = 10x?

A. (−6, −60)
B. (8, 90)
C. (8, 70)
D. (−10, −80)

Answers

Answer 1
A is a solution.
Basically, you have to plug in your coordinate to the equation. Plug in -60 for y and -6 for x. Now it should look like:
-60 = 10(-6)
Multiply 10 by -6 to get:
-60 = -60
That is a true statement because -60 equals -60. So, A is a solution to the equation. Hope this helped!

Solve the following equation:
1.3(a + 2) + 5.6 = 17.3

Answers

Answer:

a=7

Step by step Explanation:

Step 1: Simplify both sides of the equation.

1.3(a+2)+5.6=17.3

(1.3)(a)+(1.3)(2)+5.6=17.3(Distribute)

1.3a+2.6+5.6=17.3

(1.3a)+(2.6+5.6)=17.3(Combine Like Terms)

1.3a+8.2=17.3

1.3a+8.2=17.3

Step 2: Subtract 8.2 from both sides.

1.3a+8.2−8.2=17.3−8.2

1.3a=9.1

Step 3: Divide both sides by 1.3.

1.3a      9.1

1.3     =   1.3

a = 7

Answer:

Conduction is the transfer of thermal energy through direct contact between particles of of a substance, without moving the particles to a new location. Conduction usually occurs in solids. Convection is the transfer of thermal energy through movement of particles from one location to another. Convection usually occurs in liquids. Radiation is the emission of energy as waves or particles or rays. Radiant energy is either reflected or absorbed by matter. Convection causes things like the rain cycle and radiation comes from things like the sun.

If a bowling ball is dropped out of an airplane,
what will its speed (velocity) be after 3.4
seconds, assuming no air resistance? (Hint: Use
the equation v = 32t).

Answers

Answer: The velocity of the ball is 108.8 ft/s downwards.

Step-by-step explanation:

When the ball is dropped, the only force acting on the ball will be the gravitational force. Then the acceleration of the ball will be the gravitational acceleration, that is something like:

g = 32 ft/s^2

To get the velocity equation we need to integrate over time, to get:

v(t) = (32ft/s^2)*t + v0

where v0 is the initial velocity of the ball. (t = 0s is when the ball is dropped)

Because it is dropped, the initial velocity is equal to zero, then we get:

v(t) = (32ft/s^2)*t

Which is the same equation that we can see in the hint.

Now we want to find the velocity 3.4 seconds after the ball is dropped, then we just replace t by 3.4s, then we get:

v(3.4s) = (32ft/s^2)*3.4s = 108.8 ft/s

The velocity of the ball is 108.8 ft/s downwards.

Which are solutions of the equation x2 - 16 = 0? Check all that apply.
O x=-8
O x=-4
O x= -2
O x=2
Ox=4
O x=8

Answers

Last one
Because you have to substitute it
So you do X times 2 - 16 = 0
And the only X that works is the last one cause 8 X 2 = 16 and 16 -16=0

The solutions of the given equation are x=4 and x=-4. Therefore, options B and E are the correct answers.

What is the solution of a quadratic equation?

The solutions to the quadratic equation are the values of the unknown variable x, which satisfy the equation. These solutions are called roots or zeros of quadratic equations. The roots of any polynomial are the solutions for the given equation.

The given quadratic equation is x²-16=0.

Here, x²=16

x=±√16

x=±4

So, the solutions are x=4 and x=-4.

Therefore, options B and E are the correct answers.

B)

[tex]\sqrt{53}\approx7.3\text{ units}[/tex]

Step-by-step explanation:

To find the distance between any two points, we can use the distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]

Problem 1)

We have the two points (-4, 5) and (7, 18).

Let (-4, 5) be (x₁, y₁) and let (7, 18) be (x₂, y₂).

Substitute:

[tex]d=\sqrt{(7-(-4))^2+(18-5)^2}[/tex]

Evaluate:

[tex]\begin{aligned}d&=\sqrt{(11)^2+(13)^2}\\&=\sqrt{121+169}\\&=\sqrt{290}\approx17.0\end{aligned}[/tex]

Problem 2)

We have the two points (-2, -3) and (-4, 4).

Similarly, we will let (-2, -3) be (x₁, y₁) and (-4, 4) be (x₂, y₂).

Substitute:

[tex]d=\sqrt{(-4-(-2))^2+(4-(-3))^2[/tex]

Evaluate:

[tex]\begin{aligned}d&=\sqrt{(-2)^2+(7)^2}\\&=\sqrt{4+49}\\&=\sqrt{53}\approx7.3\end{aligned}[/tex]
