Answer:
When rotating a point 90 degrees counterclockwise about the origin the point (7,4) becomes (-4,7).
Step-by-step explanation:
In other words, just switch x and y and make y negative.
The point will be inverted when (7,4) is rotated 90° counterclockwise i.e., the new point will be (4,7).
It is given that a point (7,4) is rotated 90° counterclockwise about origin.
We have to find the new point after rotation.
What do you mean by rotation counterclockwise ?
If something is moving counterclockwise that meant it is moving in the opposite direction to the direction in which the hands of a clock move.
As per the question ;
A point (7,4) is rotated of 90° counterclockwise about origin.
Let's assume (7,4) = (x , y)
If we rotate it 90°counterclockwise ; then the point will be inverted ; i.e.,
(x , y ) ⇒ ( y , x)
So ;
( 7 , 4 ) = ( 4 , 7 )
So ;
The new point will be ;
= ( 4 , 7 )
Thus , the point will be inverted when (7,4) is rotated 90° counterclockwise i.e., the new point will be (4,7).

write the equation of a line parallel to the line 2x-3y=6 that passes through (-4,-1)
Answer:
2x+3y=6 is -2/3
A line passing through 0,4 does have the same slope Because they are both parallel. Which is from a slope-intercept form. This is needed in an equation of a line.

A scuba diver descends in the water at a rate of 20 1/2 feet per minute for 2.8 minutes. He immediately changes course when he sees a large fish and ascends at a rate of 25 feet per minute for 2 minutes. What is the scuba diver's position relative to sea level after the 4.8 minutes?
Answer:
7.4 feet below sea levelStep-by-step explanation:
Assumed the starting point is the sea level 0.
After 2.8 min the diver is at position:
20 1/2 * 2.8 = 20.5 * 2.8 = 57.4 feet below sea levelThe position change after next 2 minutes:
25*2 = 50 feetThe position of the diver after 4.8 min:
57.4 - 50 = 7.4 feet below sea levelAnswer:

Question : The total cost (in dollars) for a company to manufacture and sell x items per week is C(x) = 70x + 300. If the revenue brought in by selling all x items is R(x) = 90x - 0.03x^2 find the weekly profit. How much profit will be made by producing and selling 70 items each week? Hint : P(x) = R(x) - C(x)
P(x) = ______
P(70) = $ _______
Answer:
p(x)=20x+300+0.03x^2
p(70)=1553 dollars
You've poured some 8% (by mass) alcohol solution and some 12% alcohol solution into a large glass mixing container. Now you have 760
grams of 10% alcohol solution. How many grams of 8% solution and how many grams of 12% solution did you pour into the mixing container?
Step-by-step explanation:
you mixed an 8% and a 12% solution together.
so, you get (8%×mass1 + 12%×mass2)/((mass1 + mass2)/2) as resulting % of the combined solution.
since the result is 10%, which is precisely the arithmetic middle
(8 + 12)/2
we see that mass1 = mass2.
in other words : the same quantity (mass) of the 8% solution and the 12% solution was mixed together.
so, 760g = 2×mass
=>
mass = 380g
380g of the 8% solution and 380g of the 12% solution were mixed together.

10. Insert three numbers between 24 and 44 to give five numbers in an arithmetic progression. Consider: a = 24 and 44 as the last term. Calculate the difference (d) to insert the three numbers.
Answer:
29,34,39
Step-by-step explanation:
t1=24
tn=t1+(n-1)d
t5=24+(5-1)d
t5=44
44-24=20
(5-1)*d=20
d=5
t5=24+5(5-1)=44
so sub it for 2,3,4
t2=24+5(2-1)=29
t3=24+5(3-1)=34
t4=24+5(4-1)=39
Someone help me PLEASE it’s DUE
Answer:
20 inches
Step-by-step explanation:
When the instructions say a triangle is similar, it basically means they are exactly the same unless otherwise specified.
With this, we just need to find the ratio.
We can see that DE is 6 inches while AB is 18 inches.
This means that the ratio between DEC and ABC is 1:3, respectively.
So if AC is 30, that means DC should be 10.
All we have to do now is subtract DC from AC to find AD
30 - 10 = 20
So AD is 20 inches
I'm pretty sure there is a more mathematical approach to this but this is good enough to solve any problem like this.
Answer:
20 inches
Step-by-step explanation:
Set up a proportion
BA/AC = ED/DC
You are given that BA = 18, AC = 30, ED = 6
18/30=6/
18/6 = 3
30/3 = 10 = DC
Sense DC = 10
AC-DC
30-10=20

Distributive PropertiesWe want to solve;
1568 × 184 - 1568 × 84
Now, to solve this, we need to understand distributive property which is;
a(b + c) = ab + ac
Thus, applying distributive property to our question, we will have;
1568(184 - 84)
>> 1568(100)
>> 156800
