Answer: Rectangle and Trapezium

Step-by-step explanation:

If you have the slopes, then you can tell when two lines are parallel.

A rectangle has two pairs of parallel sides

A trapezium has exactly one pair of parallel sides

Find the perimeter of an isosceles triangle ABC. Side AB=4, and the base BC=3. Angles B & C are both 70 degrees.
MA_775_DIABLO [31]

Answer:

11 units

Step-by-step explanation:

Since <em>∆ABC is isosceles, it means that at least two sides are congruent/equal in length</em>.

<em>Sides CA and AB are congruent</em>, since BC is the base. So, <em>CA = 4</em>.

That means the perimeter is <em>4 + 4 + 3 </em>= 11 un

Select the two binomials that are factors of 64x^2 – 36.
lara [203]
64x² - 36 factors to be (8x + 6)(8x - 6)

Option C is your answer. 

HOWEVER, I cannot tell what the operation is supposed to be performed because of the way it is showing up above (see attached pic). So I can also just simplify it.

64x² - 36 becomes 4(16x² - 9) or 4(4x - 3)(4x + 3)

64x² + 36 becomes 4(16x² + 9)

A ball is thrown straight up from a height of 3 ft with a speed of 32 ft/s. Its height above the ground after x seconds is given
IceJOKER [234]

Answer:

19ft

Step-by-step explanation:

Given the height of a ball above the ground after x seconds given by the quadratic function y = -16x2 + 32x + 3, we can find the maximum height reached by the ball since we are not told what to look for.

The velocity of the ball is zero at maximum height and it is expressed as:

V(x) = dy/dx

V(x) = -32x+32

Since v(x) = 0

0 = -32x+32

32x = 32

x = 32/32

x = 1s

Get the height y

Recall that y = -16x² + 32x + 3.

Substitute x = 1

y = -16(1)²+32(1)+3

y = -16+32+3

y = -16+35

y = 19ft

Hence the maximum height reached by the ball is 19ft
