9514 1404 393

Answer:

  154 kPa

Step-by-step explanation:

The volume and pressure are given as inversely related. The volume increases by a factor of 10/4, so the pressure will decrease by the factor 4/10.

  (4/10)(385 kPa) = 154 kPa

A TV has an original price of $499. What is the new price after a 15% increase?
liubo4ka [24]

Given:

Original price of a TV = $499

Price increased by 15%.

To find:

The new price of the TV.

Solution:

According to the question,

New price of the TV = Original price + 15% of its original price.

\text{New price of the TV}=499+\dfrac{15}{100}(499)

\text{New price of the TV}=499+74.85

\text{New price of the TV}=573.85

Therefore, the new price of the TV is $573.85.

(g/p)(-3)<br> g(x)=2x^2+5<br> p(x)=x^2-2x
trapecia [35]

Answer:

23/15

Step-by-step explanation:

find g(-3)

    g(-3) = 2(-3)² + 5 = 2(9) + 5 = 18 + 5 = 23

Now find p(-3)

    p(-3) = (-3)² - 2(-3) = 9 - (-6) = 9 + 6 = 15

Now find g(-3)/p(-3)

  23/15

Write an equation, in slope intercept form, that passes through the points (-16,8 )
krek1111 [17]

It would be: y-y1 = m(x-x1)

y-8 = m(x+16)

y-8 = mx+16m

y = mx+16m+8

you have to calculate m, which can be possible if two coordinates are given otherwise it's the final possible answer...
