What will the sale price be of a t-shirt that has an original price of $24.99 and is on sale for 30% off
Leviafan [203]

Original price $24.99

Now it's on sale with 30% off

So the price now will be 24.99 - 30% of 24.99

Or we can say that it will be 70% of the initial price

So:

24,99 . 70% = 24,99 . 70/100 = 17,493

The price will be $17,493

Use the remainder theorem to find the remainder for (x ^5 + 32) divided by (x+2) and state whether or not the binomial is a fact
marta [7]

x+2 is a factor of x^5+32 because (by the remainder theorem) the remainder upon dividing x^5+32 by x+2 is (-2)^5+32=0.

There's also the sum of fifth powers formula,

a^5+b^5=(a+b)(a^4-a^3b+a^2b^2-ab^3+b^4)

Determine the value of a so that the line whose equation is ax+y-4=0 is perpendicular to the line containing the points (2,-5) a
soldi70 [24.7K]
First, write the equation of the line containing the points <span>(2,-5) and (-3,2).

We can use 2 point form, or point-slope form.

Let's use </span>point-slope form.

the slope m is \frac{-5-2}{2-(-3)}= \frac{-7}{5}, then use any of the points to write the equation. (ex, pick (2, -5))

y-(-5)=(-7/5)(x-2)

y+5=(-7/5)x+14/5

y= (-7/5)x+14/5 - 5 =(-7/5)x+14/5 - 25/5 =(-7/5)x-11/5


Thus, the lines are 

i) y=-ax+4      and  ii) y=(-7/5)x-11/5

the slopes are the coefficients of x: -a and (-7/5),

the product of the slopes of 2 perpendicular lines is -1, 

so 

(-a)(-7/5)=-1

7/5a=-1

a=-1/(7/5)=-5/7


Answer: -5/7
