For the number 7, begin by solving for k.
Remember your discriminant rules:
k is greater than 0, there are 2 real solutions
k is equal to 0, there is one real solution
k is less than 0, there are no real solutions

On number 8, solve for a, and then figure out the number of solutions using the rules above.

Hope this helps!

A light bulb consumes 3600 watt-hours in 3 days and 18 hours. How many watt-hours does it consume per day?

Tasya [4]

18 hours = 18/24 reduces to 3/4 of a day

3/4 = 0.75

so 3600/3.75 = 960 watts per day

Determine whether

lora16 [44]

Answer:

(a) and (b) are not equivalent

(c) is equivalent

Step-by-step explanation:

Given

$\frac{25^m}{5}$

Required

Determine an equivalent or nonequivalent expression

$(a)\ 25^{m-1$

We have:

$25^{m-1$

Apply law of indices

$25^{m-1} = \frac{25^m}{25}$

<em>This is not equivalent to </em> $\frac{25^m}{5}$ <em></em>

$(b)\ 25^{2m - 1}$

We have:

$25^{2m - 1}$

Apply law of indices

$25^{2m - 1} = \frac{25^{2m}}{25}$

<em>This is not equivalent to </em> $\frac{25^m}{5}$ <em></em>

<em></em>

<em /> $(c)\ 5^{2m-1}$ <em />

We have:

<em /> $5^{2m-1}$ <em />

Apply law of indices

<em /> $5^{2m-1} = \frac{5^{2m}}{5^1}$ <em />

<em /> $5^{2m-1} = \frac{5^{2m}}{5}$ <em />

<em>Evaluate the numerator</em>

<em /> $5^{2m-1} = \frac{25m}{5}$ <em />

<em />

<em>This is an equivalent expression</em>
