Answer:

#1 x = 31°

#2 x = 125°

Step by Step Explanation:

By the theorem of intersecting secants outside of the circle, we have:

$x=\frac{1}{2}(103\degree-41\degree)$

$\implies x=\frac{1}{2}(62\degree)$

$\implies \red{\bold{x=31\degree}}$

By the theorem of intersecting chords, we have:

$x=\frac{1}{2}(96\degree+154\degree)$

$\implies x=\frac{1}{2}(250\degree)$

$\implies \purple{\bold{x=125\degree}}$

A local grocery story has strawberries on sale for $1.45 per pound. How much would it cost to buy 5.5 pounds of strawberries? Ro

myrzilka [38]

Answer: The cost of 5.5 pounds strawberries =$ 7.98

Step-by-step explanation:

Given: A local grocery story has strawberries on sale for $1.45 per pound.

i.e. Cost for 1 pound strawberries = $1.45

Now, Cost of 5.5 pounds strawberries = 5.5 x (Cost for 1 pound strawberries)

= $ (5.5 x 1.45)

= $ 7.975 ≈ $ 7.98 [ Round to the nearest penny]

Hence, the cost of 5.5 pounds strawberries =$ 7.98

What number must be added to the expression below to complete the<br> square?<br> x² - 18x

kiruha [24]

Answer:

$\boxed {\boxed {\sf 81}}$

Step-by-step explanation:

The standard form of a quadratic is:

$ax^2+bx+c$

To complete the square, the a (leading coefficient) must be 1 and there can only be terms with variables on one side.

The expression given:

$x^2-18x$

follows these rules. Next, we divide the b (linear coefficient) by 2, then square it. Basically:

$(\frac{b}{2})^2$

The b in the expression is -18.

$(\frac{-18}{2})^2$

$(-9)^2= -9*-9= 81$

This is the number that is added.

The answer is B) -x^2-3
This is because you have an exponential graph that is flipped, hence the negative sign, and down 3.
