Answer:
10:9
Step-by-step explanation:
First ratio is 5:4. 4 is equal to Henry class
If you múltiply the ratio by 2 you get
10:8, This ratio can be compared because now Henry class has 8
2(5:4)
10:8
8:9
Meaning that the answer is 10:9
The surface area of the triangle is 1/2 * 6*8 so it is 24 sq units
The whole thing is 24* 7.5 so it is 180 sq units
Answer:
The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.
Step-by-step explanation:
Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.
hope this helps a little
Answer:
It is a factor
Step-by-step explanation:
[x³ -7x² + 8x + 16] ÷ (x + 1)
[x³ + x² - 8x² - 8x + 16x + 16] ÷ (x + 1)
[x²(x + 1) - 8x(x + 1) + 16(x + 1)] ÷ (x + 1)
x² - 8x + 16 and tye remainder is 0.
So, yes (x + 1) is a factor
The answer is C, because 10.5(10 1/2) x 7.5 (7 1/2) x 2.5 (2 1/2)= 196.875= 196 7/8
