Can somebody help me with the Math's questions on Pythagoras Theorem? Thanks

Answer:

2.4 cans cost 47.4

If you cannot buy 2.4 cans, you must buy 3 cans, then you'll pay 59.25

Step-by-step explanation:

The lawn has trapezoidal shape, so find the area of the trapezoid using formula

$A=\text{Midline}\times \text{Height}$

In the diagram, ABED is rectangle, so BE = 12 m, thus ED = 20 m - 12 m = 8 m.

Consider right triangle EDC. By the Pythagorean theorem,

$ED^2+EC^2=CD^2\\ \\ED^2+8^2=17^2\\ \\ED^2=289-64\\ \\ED^2=225\\ \\ED=15\ m$

Thue,

Height = 15 m

Find the midline:

$\text{Midline}=\dfrac{AD+BC}{2}=\dfrac{12+20}{2}=16\ m$

Hence,

$A=16\cdot 15=240\ m^2$

One can cover $100\ m^2,$ to cover $240\ m^2$ is needed

$240:100=2.4$ cans

One can costs 19.75, so 2.4 cans cost

$19.75\cdot 2.4=47.4$

If you cannot buy 2.4 cans, you must buy 3 cans, then you'll pay

$19.75\cdot 3=59.25$

2(x1/2 -7)=-6 solve for x

Andru [333]

First divide by 2, then you have
1/2x-7=-3
Then add 7 to both sides
1/2x=4
Then then divide by 1/2(which is the same as multiplying by 2)
And
x=8

39. Suppose A is an m n matrix with the property that for all b in Rm the equation Ax D b has at most one solution. Use the defi

Anna [14]

Answer: trivial solution is the only solution to Ax = 0, therefore columns must be linearly independent.

Step-by-step explanation: Recall that the columns of A are linearly independent if and only Ax = 0 had only the trivial solution. Since Ax = b has at most one solution, therefore the only solution to Ax = 0 is the trivial solution and the column vectors must be linearly independent.
