HELP<br> Use the definition of continuity and the properties of limits to show that’s the function…
Solnce55 [7]

Answer with Step-by-step explanation:

We are given that

g(x)=(x^2-3x-10)(x^2+2x^2-5x+4)

x=-1

Using property of limit

\lim_{x\rightarrow -1}g(x)=\lim_{x\rightarrow -1}(x^2-3x-10)(3x^2-5x+4)

=(1+3-10)(3+5+4)

=(-6)(12)

=-72

g(-1)=(1+3-10)(1+2+5+4)

g(-1)=(-6)(12)=-72

\lim_{x\rightarrow -1}g(x)=g(-1)

Hence, the function is continuous at x=-1

Sidana [21]

Answer:

She will earn £9.01 per hour after the pay rise

Step-by-step explanation:

Here, we want to calculate a value, given the percentage of the pay rise

The pay rise is thus;

8.50 + 6% of 8.50

= 8.50 + (6*8.5)/100

= 8.50 + 0.51

= £9.01

1. The nominal rate on Sandra's loan is 7.125%. If the interest is compounded monthly, what rate of
Mrrafil [7]

Answer:

She is actually paying a rate of 7.36% of interest.

Step-by-step explanation:

The real interest rate, as a decimal, is given by:

I = (1 + \frac{r}{n})^{n}

In which r is the interest rate and n is the number of compoundings during an year.

The nominal rate on Sandra's loan is 7.125%, compounded monthly:

This means that r = 0.07125, n = 12

So

I = (1 + \frac{0.07125}{12})^{12} = 1.0736

As a percentage: 1.0736*100 = 107.36% - 100% = 7.36%

She is actually paying a rate of 7.36% of interest.
