Answer: 42.5 m
Step-by-step explanation:
Split the figure into a rectangle and a triangle.
Find the areas of the rectangle and the triangle seperately and add them together.
Rectangle: 7 x 5 = 35
Triangle: 5 x 3/2 = 7.5
35+7.5= 42.5m
Let A be attendance, t the temperature and n the number of days. Then,
A


A=k

Where k is a constant of proportionality;
If A=3200, T=88 and n=8, then k,
3200=

3200=11k
k=

Rewriting the equation and replacing the value of k,
A=

When t=92 and n=12
The A=

A=

A= 2231
Answer: G=4
Step-by-step explanation:
We will break this down into its parts:
We know that this is a fraction where the numerator is √(-1) = i
The denominator:
4 - 3i - (2 + 5i); we put 2 + 5i in brackets because we are to subtract its quantity.
Simplifying the denominator:
4 - 3i - 2 - 5i
= 2 - 8i
Now, we write the expression in fractional form:
i / (2 - 8i)
To remove an imaginary number from the denominator, we multiply and divide by its conjugate. The conjugate of a + bi is a - bi
i(2 + 8i) / (2² - (8i)²)
= (-8 + 2i) / (4 + 64)
= -2/17 + i/34
