Answer:

y  = 112

Step-by-step explanation:

If  y varies directly as the square of x

mathematically;

y ∝ x²

y = kx² where 'k' is the constant of proportionality

let u know the value of k for this equation by making k the subject of the formular from y = kx²

divide both sides by x²

k = y / x²

given that  y = 567 x = 9

k = 567/(9)²

k = 567/81

k = 7

now to get the value of  y when x = 4

from the equation conneting x, y,

y = kx²

y = 7 × (4)²

y = 7 × 16

y  = 112

Can someone help me? ​
Rasek [7]

Step-by-step explanation:

given \:  - 5n = 4m

making m the subject first by dividing through by 4

\frac{ - 5}{n}  =  \frac{4m}{4}

m =  \frac{ - 5n}{4}

from the question, given n = -1 ,0 ,1

so when n= -1

m =  \frac{ - 5( - 1)}{4}

m =  \frac{5}{4}

when n=0

m =  \frac{ - 5(0)}{4}

m =  \frac{0}{4}

m = 0

when n=1

m =  \frac{ - 5(1)}{4}

m =  \frac{ - 5}{4}

How to find a volume of a triangular prism​
arlik [135]

Answer:

Remember the formula for calculating volume is: Volume = Area by height. V = A X h.

For a triangle the area is calculated using the formula: Area = half of base by altitude. A = 0.5 X b X a.

So to calculate the volume of a triangular prism, the formula is: V = 0.5 X b X a X h.

Step-by-step explanation:

hope it helps <33!

If m 24 is 53°, what is the m26?
hodyreva [135]

Answer:

m∠8 = 49°

Step-by-step explanation:

∠7 and ∠8 are same-side interior angles.

Remember, same-side interior angles are supplementary. This means that the sum of the angles is 180°.

Let's use the variable 'x' to represent the unknown measure of angle ∠8.

131 +x=180

131-131=0 (cancels itself out)

180-131=49

x=49

Therefore, the measure of ∠8 is 49°.
