check the picture below.

notice 2002, is just a tiny drop from the red line, 2000 is hardly below 2002, so is also close to the red line, and 1998 is also.

now, 1996 is a tad farther than 1998.

to be fair, I'd say 2002, 2001 and 1998, but off all the provided sets, 1998, 2002 and 2000 works.

The oblique pyramid has a square base with an edge length of 5 cm. The height of the pyramid is 7 cm.

Tamiku [17]

Answer:

58 cm³

Step-by-step explanation:

the volume (V) of a pyramid is calculated using the formula

V = $\frac{1}{3}$ × area of base × height

= $\frac{1}{3}$ × 5² × 7 ≈ 58 cm³

Which polar equation represents an ellipse?

tatuchka [14]

Answer:

$r=\frac{1}{3+2cos\theta}$

Step-by-step explanation:

Let us write the equations in standard form:

$r=\frac{1}{3+2cos\theta} \implies r=\frac{\frac{1}{3} }{1+\frac{2}{3}\cos \theta }$

We have

$e=\frac{2}{3}\:$ and

$ep=\frac{1}{3}$

Since the eccentricity of this conic is less than 1, the conic represents an ellipse.

The second equation is $r=\frac{3}{2+3\sin \theta}$ .

This is a hyperbola, because eccentricity is more than 1.

The third equation is $r=\frac{5}{2+2\sin \theta}$ .

This is a parabola, because eccentricity is 1.

The fourth equation is $r=\frac{2}{2-3\sin \theta}$ .

This is also a hyperbola, because eccentricity is more than 1.

Please help again I know I’m annoying with these it’s about angles ...

Helen [10]

Answer: 40°

Step-by-step explanation: angle XYW is 50°.XYW is made up of two angles XYZ and ZYW

So, XYZ+ZYW= XYW (equation 1)

Given XYZ= 10° and XYW= 50°

10°+ZYW= 50° (substituting the values of equation 1)

ZYW= 50-10

ZYW= 40°

What’s the answer. Picture is attached

Tanya [424]

y > -(1/2) x + 5 and y ≤ 3x - 2

(5,3):

3 >? -(1/2)(5) + 5 = 5-5/2 = 5/2; that's true

3 ≤ 3(5) - 2 = 13; that's true

(4,3)

3 >? -(1/2)4 +5 = 5 - 2 = 3; that's false

Answer: 2) (4,3)

Let's check the rest.

(3,4)

4 >? -(1/2)(3) + 5 = 5 - 3/2 = 7/2, true

4 ≤ 3(3) - 2 = 7, true

(4,4)

4 >? -(1/2)(4) + 5 = 5 - 2= 3, true

4 ≤ 3(4) - 2 = 10, true

Answer seems right.
