Answer:

y=4, -4

Step-by-step explanation:

2^2 + (2√3)^2 = y^2

4+ (2√3)^2 = y^2

y^2=4+12 (here we square the values inside bracket which turns 2 into 4 and when you square a square root it gets rid of the root so you are left with 3 which is multiplied to 4 and you get 12.)

y^2= 16

y=4, -4 (when you square root a positive value you get one positive and one negative answer because here (-4) x (-4) = 16 (because multiplying two negatives gives us a positive.

<h3>What is linear equation?</h3>

Linear equation is equation in which each term has at max one degree. Linear equation in variable x and y can be written in the form y = mx + c

Linear equation with two variables, when graphed on Cartesian plane with axes of those variables, give a straight line.

For the given graph the equation can be written as, y = mx+c, this is because the graph is a line which means the relationship is linear. Therefore, the equation can be written as,

y = mx + c

Now, there are two points that are on the line and the coordinates of this points are,

A = (4, 9.5)

B = (7.25, 16)

Further the slope of the equation is,

m = (16-9.5) / (7.25 - 4) = 2.0769

Since c is the y-intercept of the graph, therefore, the value of c is 1.5.

Thus, the function that can represent the given graph is y=2.0769x + 1.5.

The tent shown below has fabric covering all four sides and the floor. What is the minimum amount of fabric needed to construct

fenix001 [56]

Answer:

I believe the answer is 152 ft

Step-by-step explanation:

On the side, you would find the area of the square (8x5=40). Then, you would find the area of the triangular front (6x4=24 divded by 2 so it's 12). There are two sides of each, so 24+80=104. Then, you dfind the aarea of the bottom square (6x8=48) and add them all together to make 152

Find the 52nd term of the following arithmetic sequence.<br> 3, 9, 15, 21,

Alex Ar [27]

Answer:

309

Step-by-step explanation:

a = 3, d = 6, n 52

Nth term of an Arithmetic sequence is given as:

$t_n=a +(n-1)d \\ \therefore \: t_{52}=3 +(52-1) \times 6 \\ \therefore \: t_{52}=3 +51\times 6 \\ \therefore \: t_{52}=3 +306 \\ \huge \red{ \boxed{\therefore \: t_{52}=309 }}\\$

Simplify the following expression 4x + 3t - 2x- 4

allochka39001 [22]

Answer:

2x + 3t - 4

Step-by-step explanation:

Hi,

To simplify the expression, we must combine like terms. To start, let's combine all of the x-values.

4x + 3t - 2x - 4

When we combine 4x and -2x we get 2x.

2x + 3t - 4

We can't combine anything else. They don't have the same variables and 4 doesn't even have a variable, so 2x + 3t -4 is the simplified expression.

I hope this helps :)
