Answer:

Robert bought 13 colored pencils and 2 pencils

Step-by-step explanation:

13 x 0.60 = 7.8
2 x 0.45 = 0.9

7.8 + 0.9 = 8.70

13 colored pencils are $7.80

2 pencils are $0.9

15 total is $8.70

Write two polynomials whose sum is x to the second power and whose difference is 1
Alex777 [14]

Answer:

Therefore, the  first polynomial is:

Z=\frac{1}{2}x^2+\frac{1}{2}\\

the second polynomial is:

Y=\frac{1}{2}x^2-\frac{1}{2}\\

Step-by-step explanation:

We assume that: Z is first polynomial and Y is second polynomial.

Therefore, we have

Z+Y=x^2\\\\Z-Y=1\\\\\implies Z+Y+Z-Y=x^2+1\\\\2Z=x^2+1\\\\Z=\frac{1}{2}x^2+\frac{1}{2}\\

now, we get

\implies Z+Y-Z+Y=x^2-1\\\\2Y=x^2-1\\\\Y=\frac{1}{2}x^2 -\frac{1}{2}

Therefore, the  first polynomial is:

Z=\frac{1}{2}x^2+\frac{1}{2}\\

the second polynomial is:

Y=\frac{1}{2}x^2-\frac{1}{2}\\

the perimeter of a rectangle is 222 millimeters if the length of the rectangle is 60 millimeters what is the width of the rectan
trapecia [35]
Perimiter=legnth+legnth+width+width=2lengt+2width

lesngh=60
perimiter=60+60+2width
perimiter=120+2widht
222=120+2width
subtract 120 from both sdies
102=2width
divide by 2
51 mm=width

For the function y=-3+4cos (5pi/6 (x+4)), what is the minimum value
Elena L [17]
Function y is a function of cosine transformed by some operations, so cos can take values from interval <-1;1>, which means that this function can take values from interval <-7;-1>. The minimum value is -7. The graph will be very helpuf in this task to understand.

Examine the graph of the logarithmic function f(x).
Eduardwww [97]

Answer:

The function f(x) has a vertical asymptote at x = 3

Step-by-step explanation:

We can define an asymptote as an infinite aproximation to given value, such that the value is never actually reached.

For example, in the case of the natural logarithm, it is not defined for x = 0.

Then Ln(x) has an asymptote at x = 0 that tends to negative infinity, (but never reaches it, as again, Ln(x) is not defined for x = 0)

So a vertical asymptote will be a vertical tendency at a given x-value.

In the graph is quite easy to see it, it occurs at x = 3 (the graph goes down infinitely, never actually reaching the value x = 3)

Then:

The function f(x) has a vertical asymptote at x = 3
