Solve sint = cos2t, for –4π ≤ t ≤ –2π
e-lub [12.9K]

Answer:

-(23/6)π

-(19/6)π

-3π

Step-by-step explanation:

cos2t=cos^2t-sin^2t => cos^2t=1-sin^2t =>cos2t=1-2sin^2t

sint=1-2sin^2t, if x=sint, thenn we have 2x^2+x-1=0

Here x=0.5, x=-1, as x=sint => sint = -1 solutions for -4π to -2π is t=-3π,

sint = 0.5 solutions for -4π to -2π is t= -(23/6)*π, and t = -(19/6)*π

There are 3,250 buttons. If they are divided into groups of 8, how many buttons are there. Interpret the remainder. Show your wo
Andre45 [30]
I am going to assume that the question is asking how many buttons are in each of the 8 groups.

To find out how many buttons are in each of the 8 groups, we simply need to divide the amount of groups by the total amount of buttons.

3250 / 8 = 406.25

That is unlikely the answer, since buttons are hard to divide into quarters.

**************

This is the more likely solution. There are 8 groups of buttons, with 3250 buttons in each group. To find the total amount of buttons, we just need to multiply the number of groups of buttons there are by the amount of buttons there are in each group.

8 * 3250 = 26000

There are 26,000 buttons total.
Hope that helped =)

Beetle cellular offers cellular phone service for 39.95 a month plus one cent a minute. Salamander digital offers cellular phone
Ivahew [28]

Answer:

750 minutes

Step-by-step explanation:

Let the number of minutes be represented as x

1 cent = 0.01

Beetle cellular offers cellular phone service for 39.95 a month plus one cent a minute.

$39.95 + 0.01x

Salamander digital offers cellular phone service for 9.95 a month plus five cents a minute.

$9.95 + 0.05x

How many minutes would a person need to use a month for beetle cellular to cost the same as salamander digital?

This is calculated as:

Beetle cellular = Salamander digital

$39.95 + 0.01x = $9.95 + 0.05x

Collect like terms

$39.95 - $9.95 = 0.05x - 0.01x

$30.00 = 0.04x

x = $30.00/0.04

x = 750 minutes

A person need to use 750 minutes a month for beetle cellular to cost the same as salamander digital.
