A. What are the coordinates of the vertices of the triangle below?

Viktor [21]

Answer:

Solution given:

A.coordinate are

A(-2,3)

B(0,-3)

C(4,5)

B.Each length are :

we have

length $\sqrt{(x2-x1)²+(y2-y1)²}$

now

AB: $\sqrt{(-2-0)²+(3+3)²}$ = $2\sqrt{10}$ units

BC: $\sqrt{(0-4)²+(-3-5)²}$ = $4\sqrt{5}$ units

AC: $\sqrt{(-2-4)²+(3-5)²}$ = $2\sqrt{10}$ units

C. the figure:

By using Pythagoras law

base[b]=AB=perpendicular [p]=AC

hypotenuse [h]=BC

we have

h²=p²+b²

substituting value

( $4\sqrt{5}$ )²=2p²

16*5=2*( $2\sqrt{10}$ )²

80=2*4*10

80=80

SO IT IS RIGHT ANGLED ISOSCELES TRIANGLE.

This figure is a right triangular prism. The sides of its triangular bases are each 5 cm and the height of the triangular base i

lapo4ka [179]

Answer:

86cm³

Step-by-step explanation:

The area of the triangle is 1/2(b)(h)*2. The 1/2 and 2 cancel out as we’re doubling the small triangle to make the big triangle. Then you just multiply it times the length of the prism. So the formula ends up:

2.5*4.3*8=86cm³

Simplify the following expression as much as possible (3+I)-(5-7i)(-2+2i

Pavel [41]

Answer:

- 1 - 23i

Step-by-step explanation:

The expression is

(3+i)-(5-7i)(-2+2i)

The answer to your question can be found in the image attached below.

We need to multiply the terms and add them together

(3+i) - [ (5)(-2+2i) +(-7i)(-2+2i) ]

= (3+i) - [ -10 +10i + 14i -14i^2]

= (3+i) - [ -10 +10i + 14i +(14)]

= (3+i) - [ 4 + 24i ]

= (3+i) - 4 - 24i

= - 1 - 23i

How many license plates can be made using 3 digits and 3 letters of repeated digits and letters are allowed? how many can be mad

BARSIC [14]

26 total letters, 10 total digits

with repeated letters/numbers:

26 * 26 *26 * 10* 10*10 = 17,576,000 ways

without repeats:

26 *25*24 *10 *9*8 = 11,232,000 ways
