HELP ASAP!!!!!!!!!!!!!!!!!!What is the distance between the points (–3, 4) and (–7, 4)?

2 answers:

7 0

By the Pythagorean Theorem:

c^2=a^2+b^2

And then some refer to this as the distance formula...

d^2=x^2+y^2

And when you are dealing with two points...

d^2=(dx)^2+(dy)^2

In this case:

d^2=(-7--3)+(4-4)^2

d^2=(-4)^2+0^2

d^2=16

d=4

So the distance between the two point is 4 units.

(We could have just noticed that the y coordinates were the same and said the distance was just -3--7=4 :P, but the way I worked it is how you will almost always have to.)

Find the exact volume of a cone 6yd height 5yd base

Verdich [7]

Answer:

The exact volume of a cone is 10 yd³.

Step-by-step explanation:

Given:

Height of cone (h) is 6 yd and base (b) is 5 yd.

Now, to get the volume we need to find the radius.

So, to find radius we put the formula of base:

Let the radius be $r$

Base= $\pi r^2$

$b=\pi\times r^{2}$

$5=\pi\times r^{2}$

Dividing both sides by π and using square root on both the sides:

$5\div \pi=(\pi \times r^{2}) \div \pi$

$\frac{5}{\pi}=r^{2}$

$r^{2}=\frac{5}{\pi}-----1$

Now, putting the formula for getting the volume (v) of cone:

Volume = $\pi r^2\frac{h}{3}$

$v=\pi\times r^{2}\times \frac{6}{3}$

$v=\pi\times r^{2}\times 2$

Substituting the value of $r^2$ from equation (1), we get:

$v=\pi\times \frac{5}{\pi}\times 2$

$v=10$ yd³

Volume of cone is 10 yd³

Therefore, the exact volume of a cone is 10 yd³.

Help please! The division Axiom would allow us to say which two angles are equal?

ryzh [129]

Answer:

The correct option is;

(3) ∠ADB and ∠BDC

Step-by-step explanation:

From the division axiom, we have;

(a+a)/a = 2·a/a = 2

The given parameters are;

m∠ADC = m∠ABC

$\overline {BD}$ bisects ∠ADC and ∠ABC

Therefore;

∠ADB ≅ ∠BDC

∠ABD ≅ ∠CBD

Therefore;

∠ADB/∠CBD = ∠BDC/∠ABD

Given that m∠ADC = m∠ABC and ∠CBD = 1/2 × m∠ABC = 1/2 × m∠ADC = ∠ABD, we are allowed to say, ∠ADB and ∠BDC are equal.

50 = 5G + 2 – G What is this answer

Naya [18.7K]

Answer:

g=12

Step-by-step explanation:

50=5g+2-g

One solution was found :

g = 12

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

50-(5*g+2-g)=0

Step by step solution :

Step 1 :

Pulling out like terms :

1.1 Pull out like factors :

48 - 4g = -4 • (g - 12)

Equation at the end of step 1 :

Step 2 :

Equations which are never true :

2.1 Solve : -4 = 0

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2 Solve : g-12 = 0

Add 12 to both sides of the equation :

g = 12

One solution was found :

g = 12
