Answer:

Since this is a right triangle with one angle and hypotenuse given and opposite side unknown, we can use the definition of sine to find the unknown side.

sin 17 = x/hypotenuse = x/19

x = 19sin17 = 5.6

What is the length of CD to the nearest 10th?
Snezhnost [94]

Answer:

\huge \boxed{\mathrm{10.3 \ units}}

Step-by-step explanation:

To solve for <em>CD</em>, we can create a right triangle.

Where <em>CD</em> becomes the hypotenuse.

The length of the base of the triangle is 9 units.

The length of the height of the triangle is 5 units.

Apply Pythagorean theorem to solve for the hypotenuse.

\sf hypotenuse = \sqrt{(base )^2 +(height )^2 }

c=\sqrt{9^2 +5^2 }

c=\sqrt{106}

c \approx 10.29

Use the discriminant to describe the roots of each equation. Then select the best description.
Marrrta [24]
Let's find the discriminant of <span>x^2+9x+14=0.  Here, a=1, b=9 and c=14.

The discriminant is b^2-4ac.  Substituting the above numeric values,
                                9^2-4(1)(14) = 81-56 = 25

The sqrt of 25 is 5.  Thus, your polynomial has two unequal, real roots.

Off the point example:  If the discriminant were zero, your poly would have two real, equal roots.</span>

in a cookie jar,1/5 of the cookies are chocolate chip and 1/2 of the rest are peanut butter.What fraction of all the cookies is
Tamiku [17]
If 1/5 are chocolate chip, then 4/5 are not chocolate chip because 1 - 1/5 = 4/5.

Half of 4/5 are peanut butter. Half of 4/5 is 2/5, so 2/5 of the cookies are peanut butter.

wolverine [178]

Good morning

______

Answer:

2/3 < 3/4​

___________________

Step-by-step explanation:

2/3 = (2*4)/(3*4)=8/12

3/4 = (3*3)/(4*3)=9/12

Since 9/12>8/12 then 3/4>2/3
