Hey can someone tell me what -3x^2(14x^2-2x-8) equals

Answer:

Step-by-step explanation:

In verse variation would be 3  = k / 2.4   so k  = 7.2

So we have  y = 7.2 / 5  = 1.44

Answer is 1.44.

Answer:

Hence, the value of y is:

1.44

Step-by-step explanation:

It is given that:

The pair of points is on the graph of an inverse variation.

(2.4, 3) and (5, y)

We have to find the missing value y in the point.

As we know that in the inverse variation the value of y is the inverse value of x by some k.

i.e. in first point (2.4,3) let 'k' be a number such that:

Hence, the inverse is k=7.2

Now in the second point (5,y) we find the value of y as:

Hence, the value of y is:

1.44

Variation can be direct, inverse, joint or combined.

The missing value of y is (b) 1.44

The points are said to represent inverse variation.

So, we have:

[tex]x_1 \times y_1 = x_2 \times y_2[/tex]

Substitute x and y values in the equation

[tex]2.4 \times 3 = 5\times y_2[/tex]

Multiply 2.4 and 3

[tex]7.2= 5\times y_2[/tex]

Divide both sides by 5

[tex]1.44 = y_2[/tex]

Rewrite as:

[tex]y_2 = 1.44[/tex]

Hence, the missing value of y is (b) 1.44

Answer:

q = 2

Step-by-step explanation:

p α 1/q

p = k/q

Where, k = constant of proportionality

p = 14 ; q = 12

We can obtain the value of k

p = k/q

14 = k/12

k = 14 * 12

k = 168

p = 168/q

pq = 168

q = 168 / p

Value of q, when p = 84

q = 168 / 84

q = 2

Answer:

A=368 miles

B= 356.3 miles

Step-by-step explanation:

Given data

Let the two trains be A and B

A+B=724.3----------1

A-B=11.7--------------2

From eqn 1

A= 724.3-B

put this in place of A in eqn 2

724.3-B-B= 11.7

724.3-2B= 11.7

724.3-11.7= 2B

712.6=2B

B= 712.6/2

B= 356.3 miles

Put B=356.3 in eqn 1

A+356.3=724.3----------1

A= 724.3-356.3

A=368 miles

Answer:   534

Step-by-step explanation:

an=a1+(n-1)d

Here,

d is the common difference

=>a2-a1=12-3=9

&  a1=3

a60=3+(60-1)9

a60=3+(59)*9

a60=3+531

a60=534

60th term is 534.

Answer:

60th term = 534

Step-by-step explanation:

The easier way:

3 + (60 -1) (9)

3 + (59) (9)

3 + (531) = 534

Answer:

648 cm³

Step-by-step explanation:

For Cuboid

l = 12cm

b = 9cm

h = 6cm

Now, The volume of a cube is

l × b × h

12 × 9 × 6 cm

108 × 6 cm

648 cm³

Thus, The volume of a cuboid 12cm long 9 sm broad and 6 cm high is 648 cm³

Answer:

Step-by-step explanation:

The square root of 9 is 3, while the square root of 4 is 2

3 x 2 = 6

So

A is true

B is true

C is true because we can multiply the two terms of the root and mantain the same root. In fact √36 = 6

D is wrong because the result of the expression is not 6

E is wrong for the same reason of D

F wrong because the result of the expression is 12

Answer:

Answer:

x = 80°

Step-by-step explanation:

The measure of the angles of the inside of a triangle, when added result in 180°

58° + 42° + x = 180°

x = 180° - 42° - 58°

x = 80°
