Read all of the statements about scale drawings below.

Mathematics
1 answer:
Sever21 [200]3 years ago
7 0

Answer:

The first and second statements are true

Step-by-step explanation:

Scale drawings are easier to work with than the actual object because they help a person understand the measurement better because they have scales

They should have the same proportion as the actual object in order to help calculate the real measurement of the object using the scale ratio

Maggie’s brother is 12 years younger that three times her age . The sun of their ages is 44 . How old is Maggie
meriva
I'm not sure if this is right but you can set up an equation and solve to find Maggie's age:

Maggie's brother's age = b
Maggie's age = m

b = 12 - 3m
44 = 12-3m
12-3m = 44
-12 -12
-3m = 32
÷ 3 ÷3
m = 10.67

So this would be Maggie's age

I hope this helped :)

Which of the following is NOT equivalent to 40/100?
frozen [14]

Answer:

Option C

Step-by-step explanation:

40/10 simplifies to 4.

40/100 simplifies to 0.40.

\frac{40/10}{10/10} =\frac{4}{1} =4

\frac{40}{100} =0.40

Therefore:

\frac{40}{10}\neq  \frac{40}{100}

Option C should the the correct answer.

Over which interval is the graph of f(x) = –x2 + 3x + 8 increasing?
vivado [14]
Hello there!

To find the increasing intervals for this graph just based on the equation, we should find the turning points first.

Take the derivative of f(x)...
f(x)=-x²+3x+8
f'(x)=-2x+3

Set f'(x) equal to 0...
0=-2x+3
-3=-2x
3/2=x

This means that the x-value of our turning point is 3/2. Now we need to analyze the equation to figure out the end behavior of this graph as x approaches infinity and negative infinity.
Since the leading coefficient is -1, as x approaches ∞, f(x) approaches -∞ Because the exponent of the leading term is even, the end behavior of f(x) as x approaches -∞ is also -∞.

This means that the interval by which this parabola is increasing is...
(-∞,3/2)

PLEASE DON'T include 3/2 on the increasing interval because it's a turning point. The slope of the tangent line to the turning point is 0 so the graph isn't increasing OR decreasing at this point.

I really hope this helps!
Best wishes :)
