Por lo tanto, los valores de y correspondientes son 3, 2, 4 y 8
Explicación paso a paso:
Dada la función f (x) = -5x + 3
Cuando x = 0
f (0) = -5 (0) + 3
f (0) = 0 + 3
f (0) = 3
Cuando x = 1/5
f (1/5) = -5 (1/5) + 3
f (1/5) = -1 + 3
f (1/5) = 2
Cuando x = -1/5
f (-1/5) = -5 (-1/5) + 3
f (-1/5) = 1 + 3
f (-1/5) = 4
Cuando x = -1
f (-1) = -5 (-1) + 3
f (-1) = 5 + 3
f (-1) = 8
Answer:
squaare root of 70<pi squared<10
Step-by-step explanation:
Talking about square root of 70, you can take the answer by approximation. u know square of eight is sixty four and square of nine is eighty one. so 70's square root shluld be between eight and nine. And as the value of pi is 3.14... when square of pi is considerd it should be >9 but <10 as pi>3. So 10 become te greatest
Nine year olds --> 36
ten year olds ----> 48
then simpifly this as if you would to a fraction
6/8 so the ratio would be 6:8
Answer:1
Step-by-step explanation:
To find the ratio of the volume of sphere A to B
We get
A:B
V=4/3πr^3:4/3πr^3
4/3πr^3×3/4πr^3
Ratio of A to B
=1
