An art exhibit at a local museum features several similarly shaped metal cubes welded together to make a sculpture. The smallest

borishaifa [10]

Answer: Length of other edges will be 7.5 inches, 8 inches, 9 inches, 10.5 inches, 12 inches.

Explanation:

Length of smallest cube = 6 inches

Ratio of similarity to the smallest cube is given as follows:

1) 1.25

So, length of other edge will be

$1.25\times 6=7.5\ inches$

2) 4:3

So, the length of other edge will be

$\frac{4}{3}\times 6=8\ inches$

3) 1.5

So, length of other edge will be

$1.5\times 6=9\ inches$

4) 7:4

So, length of other edge will be

$\frac{7}{4}\times 6=10.5\ inches$

5) 2

So, length of other edge will be

$2\times 6=12\ inches$

Write in slope intercept form an equation of the line that passes through the given points

Tpy6a [65]

Answer:

The desired equation is y = x + 8.

Step-by-step explanation:

As we move right from (-2,6) to (4,12), x increases by 6 and y also increases by 6. Thus, the slope, m, m = rise / run, is m = 6/6, or just m = 1.

Start with the slope intercept form y = mx + b. Since m = 1, we now have y = x + b. Subbing 4 for x, 12 for y, we can find b: 12 = 4 + b. Thus, b = 8.

The desired equation is y = x + 8.

The tangent line to y= f(x) at (4,-6) passes through the point (10,9) Compute the following, f(4) and f'(4)

Anni [7]

The solution to your problem is as follows:

The tangent line passes through (4,-6), so x = 4 when y = -6

=> f(4) = -6

The tangent line will have a constant gradient.

gradient is m = (-6 - 9)/(4 - 10) => 5/2

Equation is y - 9 = (5/2)(x - 10)

=> y - 9 = (5/2)(x-10)

i.e. y = (5/2)(x-10) + 9
 y = (5/2)x - 25 + 9 = y = (5/2)x - 16

Now, f '(x) = dy/dx = 5/2

so, f '(4) = 5/2....i.e. gradient is 5/2 whatever the value of x.

I hope my answer has come to your help. Thank you for posting your question here in Brainly.
