Answer:

The slope is 1 and the y-intercept is -1.

Step-by-step explanation:

$\frac{y{2} }{x[2] } -\frac{y_{1} }{x_{1} }$

Then plug in the numbers:

$\frac{-1}{0} -\frac{-4}{3}$

And then solve it: you'll get $\frac{3}{3}$ = 1.

And the y-intercept is -1.

Solve seven 2/3-1 2/4+3 6/8 choose the numbers to complete complete the next number numbers may be used once or not at all

Bezzdna [24]

Answer:

9 11/12

Step-by-step explanation:

Solve 7 2/3-1 2/4+3 6/8

We are to the above fractions

7 2/3 - 1 2/4 + 3 6/8

The Lowest Common Denominator = 24

(7 - 1 + 3) + ( 2/3 - 2/4 + 6/8)

9 + (16 - 12 + 18/24)

9 + 22/24

Given: m∠A = m∠C = 90° AB ║ DC Prove: ∆ABD ≅ ∆CBD

Genrish500 [490]

Answer:

Angle-Angle-Side (AAS)

Step-by-step explanation:

Given triangles; ΔABD and ΔCBD

<A = <C = $90^{0}$ (right angle property)

AB ║ DC (given)

Then,

DA ║ CB

<B ≅ <D (congruent property)

DB ≅ BD (similarity property)

<D + <B = <B + <D (complementary angles, and property of triangles)

Therefore by Angle-Angle-Side (AAS),

∆ABD ≅ ∆CBD

What is the surface area of a cylinder that is 5 centimeters high and has a diameter of 1.5 centimeters?

olchik [2.2K]

The surface area of cylinder is 8.625 $\pi$ $cm^{2}$ , if the cylinder has 5 centimeters high and 1.5 cm of diameter.

Step-by-step explanation:

The given is,

Cylinder has a 5 centimeters height

Diameter of the cylinder is 1.5 centimeters

Step:1

Formula for the surface area of cylinder is,

$A=2\pi r h + 2\pi r^{2}$ ......................................(1)

Where,

h - Height of cylinder

r - Radius of cylinder

From the values of h and r,

$r=\frac{d}{2}$

= $\frac{1.5}{2}$

r = 0.75 cm

From the formula,

= ( 2 × $\pi$ × 0.75 × 5 ) + ( 2 × $\pi$ × $0.75^{2}$ )

= ( 7.5 $\pi$ ) + ( 1.125 $\pi$ )

A = 8.625 $\pi$ $cm^{2}$

Result:

The surface area of cylinder is 8.625 $\pi$ $cm^{2}$ , if the cylinder has 5 centimeters high and 1.5 cm of diameter.
