Is the following statement true? Explain.
" For any two angles A and B, cos (A+B)=cos (A)+cos (B) "
Step-by-step explanation:
We can prove the statement is false by proof of contradiction:
We know that cos0° = 1 and cos90° = 0.
Let A = 0° and B = 90°.
Left-Hand Side:
cos(A + B) = cos(0° + 90°) = cos90° = 0.
Right-Hand Side:
cos(A) + cos(B) = cos(0°) + cos(90°)
= 1 + 0 = 1.
Since LHS =/= RHS, by proof of contradiction,
the statement is false.
This recipe makes 18 shortbread fingers.
Rose follows this recipe, but only wants to make 3 fingers.
How much of each ingredient does she need?
Recipe: Makes 18
120 g butter
60 g sugar
180 g flour
(I don't know if this is the method you are supposed to use, but I believe you will still get the same answer!)
Answer: 20 g butter, 10 g sugar, 30 g flour
Step-by-step explanation: First off, if we look at 3 and 18, you notice that three is a factor or 18, going into the number 6 times.
So, if you are making 6 times less of the original amount, divide each measurement by six to give you your answer.
120/6 = 20
60/6 = 10
180/6 = 30
Please hurry; The number of bacteria in a culture grows exponentially. It can be modeled with the function f(x) = 20 (2^x).

What type of transformation transforms (a, b) to (-a, b)?
a reflection over the y-axis
a translation of 1 unit down
a reflection over the x-axis
a translation of 1 unit up
Answer:
A reflection over the y axis .
Step-by-step explanation:
Given : Transforms (a,b) to (-a,b).
To find : What type of transformation.
Solution : We have given
Parent function : (a,b) .
Transformed : (-a ,b).
Transformation rule of reflection over y axis : ( x, y) →→ ( -x ,y).
Then we can say in transformation (a,b) →→→→ (-a,b).
Therefore, A reflection over the y axis

A line has a slope of -1/10
and includes the points (1, -6) and (t, -5). What is the value of t?
Answer:
-9
Step-by-step explanation:
Here we use the slope formula: m= y2-y1/x2-x1. We simply plug in the numbers we know: -1/10 = -5+6/t-1. Then we solve for t. Multiply both sides by (t-1) so -1/10 (t-1)= 1. Then multiply both sides by -1/10 so t-1= -10 and then add one to both sides so t=-9.

In a marketplace, a box of peaches can be purchased for $77.95 per box. One box
contains 78 peaches. How much would you have to pay to buy 4 peaches?
(Hint: Convert 4 peaches into dollars.)
Round your answer to the nearest hundredth. Do not type the units ($) in the space
below.
Answer:
4
Step-by-step explanation:
This question can be solved by proportions, using rule of three.
We have that:
You buy 78 peaches for $77.95. How much you pay to buy 4 peaches?
78 peaches - $77.95
4 peaches - x
[tex]78x = 4*77.95[/tex]
[tex]x = \frac{4*77.95}{78}[/tex]
[tex]x = 4[/tex]
You pay $4 for 4 peaches.

you need 1661.06 ft squared of carpet to completely cover the floor or a round room. what is the diameter of the room.
Answer:
46 ft
Step-by-step explanation:
A = π×d²/4

= √4×1611.06 / 3.14
=√ 2116
= 46 ft
Answer:
46 feet squared

A = π×d²/4
d² = √(4×A /π)
= √(4×1611.06 / 3.14)
= 2116
= 46 ft squared
