Now, if you notice the picture below

the amplitude of the graph we have above, is squished by half, what in sin(θ) would be an amplitude of 1 above the red midline and 1 below it, for the graph above became 1/2 above the midline and 1/2 below it, for an amplitude of 1/2

now, sin(θ) starts off from 0 and goes up then down, now, if you simply give it a negative leading coefficient, the graph will flip upside-down, or -1/2

if we look at the period of the graph above, is 2π, and the period of sin(θ) is also 2π, so, no change on the period

but the graph above is shifted, from a midline at y = 0, to y = -2, so it has a vertical shift of -2

thus \bf y=-\cfrac{1}{2}sin(\theta)-2

PLZ help!!
Paladinen [302]

Answer:

Step-by-step explanation:

At the self employed store, her monthly expense would be

y = $835

Which would plot as a horizontal line

At the franchise store here expense would be

y = 5x where x is the number of haircuts completed.

This would plot as a straight line of slope 5

The two would intersect when the two y values are equal

5 x = 835

so the same cost per month would occur at y = 835

at the franchise, she would have completed 835/5 = 167 haircuts.

If she plans on doing fewer than 167 haircuts per month, she nets more money at the franchise,

If she completes more than 167 haircuts per month, the self employed store deal keeps more money in her pocket.

Question below. Please answer it, its math.
AleksAgata [21]

Answer:

- 0.8

Step-by-step explanation:

The first thing we want to do here is simplify the expression -

\frac{3}{5}( 2x + 5 ) - 2x, Distribute the " \frac{3}{5} " to elements within the parenthesis

= \frac{3}{5} * 2x + \frac{3}{5} * 5 - 2x, Focus on simplifying the expression " \frac{3}{5} * 2x + \frac{3}{5} * 5 "

= 2\cdot \frac{3}{5}x+5\cdot \frac{3}{5} - 2x

= \frac{6x}{5}+3 - 2x, Combine fractions

= -\frac{4x}{5} + 3

= -\frac{4}{5}x + 3

So we have our simplified expression "  -\frac{4}{5}x + 3, " with -\frac{4}{5} being the coefficient of x. Our requirements are that this fraction should be expressed as a decimal, so we can simply divide the numerator by the denominator to figure that out,

- 4 / 5 = - 0.8,

Solution = - 0.8

Find the perimeter of a rectangle with a length of
Luba_88 [7]

Answer:

P = 8\sqrt{2} + 10 + 2\sqrt{6}

Can only be simplified through calculator using decimal equivalents.

Step-by-step explanation:

The perimeter of a rectangle is the formula P=2l+2w. Here l=4\sqrt{2} and w=5+\sqrt{6}. So the perimeter is:

P= 2l+2w\\P = 2(4\sqrt{2} ) + 2(5+\sqrt{6} )\\P = 8\sqrt{2} + 10 + 2\sqrt{6}

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!HELP PLEASE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Reptile [31]

Step-by-step explanation:

18% compounded monthly

vs

charges 18% compounded semi-annually.

#1 is worse than #2 because...

Since the nominal rates are the same, the card with the more frequent compounding so it would have the higher effective rat.

Let's compare them!:

(1 + .18/12)^12 = 1.19562 ---> effective rate is 19.562 per annum

(1+.18/2)² = 1.1881

1.1881 has the effective rate of 18.88% per annum

(1 + /17/4)^4 = 1.18114.. --> effective rate is 18.114% per annum

18% monthly is .18 over 12 each month = 0.015/month

so every month multiply by 1.015

total cost = $607.99 * 1.01^number of months

18% semi annual = .18/2 every six months = .09 /half year

so every half year (6 months) multiply by 1.09

total cost = $607.99 * 1.09^ (number of months/6)

17% quarterly = .17/4 every 3 months = .0425 /quarter year

so every quarter year (3 months) multiply by 1.0425

total cost = $607.99 * 1.025^(number of months/3)

HOPE THIS HELPS YOU HAVE A GREAT GREAT GREAT FANTASTIC FRIDAY!
