O is the centre of the circle, EF is a tangent, angle BCE=28 degrees, angle ACD=31 degrees.
Yuki888 [10]

Answer:

a. 28˚

b. 76˚

c. 104˚

d. 56˚

Step-by-step explanation

a. because angle between tangent and chord is equal to the angle(s) in alternate segment.

b. because angles in triangles add up to 180˚, 180-28=152 and because isosceles triangle, 152/2=76˚

c. because angles in triangles add up to 180˚ and opposite angles in a cyclic quadrilateral add up to 180˚, 31+76=107, 180-107=73, 73-28=45, angles in triangle so 180-(31+45)=104˚

d. 28*2=56˚ because angles at circumference are half angles at centre

The vertices of quadrilateral MNPQ are M(-3,-2), N(-1,4), P(2,4), Q(4,-2). Translate quadrilateral MNPQ using the rule (x,y)-&gt
notsponge [240]

Answer:

Here's what I get.

Step-by-step explanation:

The rule is (x, y) ⟶ (x + 3, y + 4).

That means you must move each point three units to the right and four units up.  Thus,

M(-3, -2) ⟶ M'(0, 2)

N(-1, 4)  ⟶ N'(2, 8)

P(2, 4)    ⟶ P'(5, 8)

Q(4, -2)  ⟶ Q'(7, 2)  

Your quadrilateral is a trapezoid. Both MNPQ and its image M'N'P'Q' are shown in the Figure below.

Simplify each expression using Product to a Power Property a. (9a)^2 b. ( 3x)^2
antiseptic1488 [7]
\begin{gathered} a)81a^2 \\ b)9x^2 \end{gathered}

1) Let's simplify those expressions making use of exponents rules:

(9a)^2=81a^2

Note that the exponent outside the parenthesis is 'distributed' over each term inside.

2) Similarly for the second expression we can state that:

(3x)^2=9x^2
