The first thing you should do is use the fact that the area of the triangle is:
A = b * h * (1/2).
From there you clear the height as a function of "c"
Then you will have a polynomial division which you must make to find the height of the triangle.
I attach the solution.
Answer:
d)
Step-by-step explanation:
c/d - 2c/5d = 5c/5d - 2c/5d = 3c/5d = x
3c/d = 5x
c/d = 5x/3 = 5/3 × x
Answer:
- f¯¹(x) =9x+18, for the pictorial(image) question
- what is the send question is it asking derivative or inverse
- If it is inverse f¯¹(x)=-x-2 as it is
- Or if it is derivative f'(x)=-1
Step-by-step explanation:
<h2>
For the image question f(x)=1/9x-2,f¯¹(x)=?</h2>
- f(x)=1/9x-2............given
- y=1/9x-2................swapping f(x) by y to Easily write
- x=1/9y-2................interchanging x and y
- 1/9y-2=x................changeling side of equation
- 9(1/9y-2)=(x)9.......multiplying both sides by 9 to override the fraction on the right side
- y-18=9x
- y=9x-18.................Return to where it were
- <em><u>f¯¹(x)=9x+18</u></em>..........swap back f¯¹(x) in the y
<h2>
For the question f(x)=-x-2,f¯¹(x)=?</h2>
- following the ☝️ arrangement
- y=-x-2
- x=-y-2
- -y-2=x
- -y=x+2
- y=-x-2
- f¯¹(x)=-x-2
Answer:
4.2 x 10⁶
Step-by-step explanation:
The problem says that there are 6x 10² times as many red blood cells as white blood cells. This means that you will need to multiply the given number of white blood cells, which is 7 x 10³ by 6x 10².
To do this, first you multiply the coefficients:
7 x 6 = 42
Next you combine the exponents of the 10s, because their bases are the same, we just add the exponents when you multiply them and copy the base:
10² x 10³ = 10⁵
So the result would be:
42 x 10⁵
However the following the form of scientific notation, you need to move the decimal one more time so that means you add one more to the exponent of 10.
4.2 x 10⁶
