The side lengths of a square measure 25.3 cm. Estimate the area of the square.

s2008m [1.1K]

Estimate, ok
area=side^2
if we round
25^2=625
25.3 is slighly bigger so maybe 632 squaer centimters or something

Please i need help on my math

Kamila [148]

Answer:

$V = \pi (2.5)^2h$

Step-by-step explanation:

The formula for the volume of a cylinder, is V = π r^2 h. It shows that the diameter is 5. But we need the radius. The radius is half of the diameter. So, 5/2. This gets you 2.5.

The equation is now:

V = π(2.5)^2h

This is the answer.

$V = \pi (2.5)^2h$

Let T:R²->R² be a linear transformation ,and assume that T (1,2)=(-1,1) and T(1,-1)=(2,3)

zavuch27 [327]

Answer:

(-4,-1)

Step-by-step explanation:

We are given T(1,2)=(-1,1) and T(1,-1)=(2,3) and T is a linear transformation.

This implies for scalars a and b that

T(a(1,2)+b(-1,1))=aT(1,2)+bT(-1,1)

T((a,2a)+(-b,b))=a(-1,1)+b(2,3)

T((a-b,2a+b))=(-a,a)+(2b,3b)

T((a-b,2a+b))=(-a+2b,a+3b)

This means we should be able to solve the system below to find a and b for T(3,3):

a-b=3 and 2a+b=3

Add equations to eliminate b and solve for a:

3a=6

Divide 3 on both sides:

a=2

If a-b=3 and a=2, then b=-1.

Plug in a=2, b=-1:

T((a-b,2a+b))=(-a+2b,a+3b)

T((2--1,2×2+-1)=(-2+2×-1,2+3×-1)

T(3,3)=(-4,-1).

The list shows the price of a gallon of gasoline at 11 gas stations. $4.20, $4.09, $4.35, $4.39, $4.79, $4.55, $4.50, $4.22, $4.

Sauron [17]

The range of a list of numbers is the biggest number minus the smallest number. In this case, it is $4.79-$4.09 which equals $0.70.
