From the diagram below, if AC =40, CD=10, and DB=8, then what would be the length of AB?
saveliy_v [14]

The length of AB would be 38 units

<h3>How to determine the length AB?</h3>

The attached image represents the missing piece in the question

Considering the triangle BCD;

Calculate the length BC using the following Pythagoras theorem

BC^2 = CD^2 + BD^2

This gives

BC^2 = 10^2 + 8^2

Evaluate

BC^2 = 164

Considering the triangle CBA;

Calculate the length AB using the following Pythagoras theorem

AB^2 = AC^2 - BC^2

This gives

AB^2 = 40^2 - 164

Evaluate

AB^2 = 1436

Take the square root

AB = 38 (approximated)

Hence, the length of AB would be 38 units

H(t) = –16t2 + 14t find the maximum height
guajiro [1.7K]
The height is represented as y and the time is represented as x. 


To find the maximum height (since this is a parabola that faces downwards) we need to find the vertex.


Vertex (x) = \frac{-(b)}{2a}

b = 14
a = -16

Substitute
\frac{-14}{2(-16)} =  \frac{-14}{-32}  =  \frac{7}{8}

Now plug 7/8 to t 
-16(7/8)^2 + 14(7/8)
-16(49/64) + 14(7/8)
-12.25 + 12.25

Find the equation of the line with the given properties. Passes through (4, -5) with a slope of -1\2
Setler [38]

y=-\frac{1}{2}x-3

Explanation

when you know the slope and a passing point of the line, you can find the equation of the line by replacing in the slope-point equation ,it is given by:

\begin{gathered} y-y_1=m(x-x_1) \\ \text{where } \\ m\text{ is the slope} \\ \text{and} \\ (x_1,y_1)\text{ is a point from the line } \end{gathered}

then

Step 1

a)Let

\begin{gathered} \text{slope}=-\frac{1}{2} \\ \text{ Point=(4,-5)} \end{gathered}

now,replace and solve for y

\begin{gathered} y-y_1=m(x-x_1) \\ y-(-5)=-\frac{1}{2}(x-4) \\ y+5=-\frac{1}{2}x+\frac{4}{2} \\ y+5=-\frac{1}{2}x+2 \\ \text{subtract 5 in both sides} \\ y+5-5=-\frac{1}{2}x+2-5 \\ y=-\frac{1}{2}x-3 \end{gathered}

therefore, the answer is

y=-\frac{1}{2}x-3

I hope this helps you

( PLEASE HELP WITH THIS QUESTION)
Ostrovityanka [42]

Answer: Yes it is possible

Example: Yeast is a single-celled fungus.

There are probably other types of fungus that are single-celled. However, some other fungi are multi-celled. You will likely need more information about the organism under the microscrope before you can classify it properly.
