Comparing the temperature of a coolant before and after use in a machining process.

Step-by-step explanation:

The temperature of a coolant in the polar region was found to be modeled by the equation t=(8x-55)° where t is the final fluid temperature after being used for cooling ,x is the time the fluid is applied on the cutting edge and -55 is the normal temperature of the fluids used for cooling processes in a machine garage.

If m varies directly as v² and m =3, when v=2, calculate the value of m when v=9

KonstantinChe [14]

Answer:

m=243/4 when v=9.

Step-by-step explanation:

We know that when y varies directly with x², the formula of direct proportion is

y=kx²

where 'k' is the constant of variation.

As m varies directly with v², and m=3 when v=2

m=kv²

k=m/v²

= 3/(2)²

=3/4

Hence, k=3/4

so when v=9 then the expression becomes

m=kv²

substituting v=9 and k=3/4

m= 3/4(9)²

=3/4 × 81

=243/4

Therefore, m=243/4 when v=9.

A cube whose edge is 20 cm 1 point

Sav [38]

Answer:

Unpainted surface area = 514.28 cm²

Step-by-step explanation:

Given:

Side of cube = 20 Cm

Radius of circle = 20 / 2 = 10 Cm

Find:

Unpainted surface area

Computation:

Unpainted surface area = Surface area of cube - 6(Area of circle)

Unpainted surface area = 6a² - 6[πr²]

Unpainted surface area = 6[a² - πr²]

Unpainted surface area = 6[20² - π10²]

Unpainted surface area = 6[400 - 314.285714]

Unpainted surface area = 514.28 cm²

Given that Y= 3x – 8, what is the sum of the gradient and intercept of the linear equation? *

chubhunter [2.5K]

Answer:

- 5

Step-by-step explanation:

The equation of a line in slope - intercept form is

y = mx + c ( m is the slope (gradient) and c the t- intercept )

y = 3x - 8 ← is in slope- intercept form

with gradient m = 3 and y- intercept c = - 8 , thus

m + c = 3 + (- 8) = 3 - 8 = - 5
