What's the answer?????????????

Answer:

BD = 12 :)

Step-by-step explanation:

Alright, we'll need the Pythagorean theorem for this!

So, the length of AC is 10. That means the lengths of AD and DC are both half of that, which is 5 :)

DC = 5

We already know that BC = 13, so we can plug in these values into the pythagorean theorem for the right triangle BDC:

BD^2 + DC^2 = BC^2

BD^2 + 5^2 = 13^2

BD^2 + 25 = 169

BD^2 = 169 - 25 = 144

BD = √144 = 12 :)

Can I get an answer?

Reil [10]

coordinate of B= (2+3,0) = (5,0)

by pythagoras' theorem,

height of triangle^2 + half length of AB^2 = AC^2

height of triangle^2 = 3^2-1.5^2

height of triangle ^2= 6.75

height of triangle= √6.75

coordinates of C= (1.5,√6.75)

What is the domain of the function f(x) =x+1/<br> X^2-6x+8?

SpyIntel [72]

Answer:

The domain of the function is all real values of x, except $x = 4$ and $x = 2$

Step-by-step explanation:

We are given the following function:

$f(x) = \frac{x+1}{x^2-6x+8}$

It's a fraction, so the domain is all the real values except those in which the denominator is 0.

Denominator:

Quadratic equation with $a = 1, b = -6, c = 8$

Using bhaskara, the denominator is 0 for these following values of x:

$\Delta = (-6)^2 - 4(1)(8) = 36-32 = 4$

$x_{1} = \frac{-(-6) + \sqrt{4}}{2} = 4$

$x_{2} = \frac{-(-6) - \sqrt{4}}{2} = 2$

The domain of the function is all real values of x, except $x = 4$ and $x = 2$

Jose is baking cakes. He needs 3/4 of butter for each cake. One stick of butter is a 1/2 of a cup. How many sticks do he need to

Anastaziya [24]

Answer: 6 sticks

Step-by-step explanation:

Given

Joe needs $\frac{3}{4}$ butter for each cake

One stick of butter is equivalent to 0.5 cup

So, joe need

$\dfrac{3}{4}\times \dfrac{1}{2}=\dfrac{3}{8}\ \text{cup}$

for each cake

To bake 8 cakes, it is

$\Rightarrow \dfrac{3}{4}\times 8=6\ \text{sticks}$
