Alexandra has a stand in the marketplace where she sells ground cumin. She has a fixed amount of weekly expenses, and she sells her cumin for \$7.20$7.20dollar sign, 7, point, 20 per kilogram. If she sells 909090 kilograms of cumin, her weekly net profit is \$414$414dollar sign, 414.

Answer:

sin = o/h = 5/13

cos = a/h = 12/13

tan = o/a = 5/12

o - opposite

a- adjacent

h - hypotenuse

Step-by-step explanation:

I guess method 1 means to deal with whole factors.

x + 5 = (x - 2)(x + 5)

for (x + 5) <> 0 we can divide both sides by this factor :

1 = x - 2

x = 3

for the second solution we deal with

x + 5 = 0

x = -5

so, for x = -5 and x = 3 both functions deliver the same output, and these are the intersection points.

method 2 : we multiply the expression out and solve it then

x + 5 = (x - 2)(x + 5)

x + 5 = x² + 5x - 2x - 10 = x² + 3x - 10

0 = x² + 2x - 15

the general solution to such a square equation is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

a = 1

b = 2

c = -15

x = (-2 ± sqrt(2² - 4×1×-15))/(2×1) =

= (-2 ± sqrt(4 + 60))/2 = (-2 ± sqrt(64))/2 = (-2 ± 8)/2 =

= -1 ± 4

x1 = -1 + 4 = 3

x2 = -1 - 4 = -5

and you get the 2 solutions again. as expected, they are the same as with method 1, of course.

Answer:

3 i think

Step-by-step explanation:

so we substitute -5 to g(x)

g(x) = -4(-5) + 3

= 20 + 3

= 23

now we substitute it to f(x)

f(x) = -2x + 49

= -2(23) + 49

= -46 + 49

= 3

Answer:

3

Step-by-step explanation:

f(x) = -2x + 49

g(x) = -4x + 3

(fºg)(x) = f(g(x)) = -2(-4x + 3) + 49

(fºg)(x) = 8x - 6 + 49

(fºg)(x) = 8x + 43

(fºg)(-5) = 8(-5) + 43

(fºg)(-5) = 3

Answer:

x=14

y=7

Step-by-step explanation:

this is a 30-60-90 triangle -- u can tell bc there is a right angle marker (90 degrees) and one angle is 30, so the other angle is 60

in a 30-60-90 triangle,,

the long leg = x√3

short leg = x

hypotenuse (the side opposite the right angle marker) = 2x

since u know the long leg is 7√3, the short leg = 7

and since the hypotenuse is 2x (twice the short leg), 7 times 2 = 14

The total amount paid by Kate as a portion of interest will be $12932.

The compound interest is the interest levied upon both the principal amount and the interest from the previous periods.

The formula for the calculation of the compound interest will be given as

[tex]A=P(1+\dfrac{r}{100^} )^n[/tex]

here,

A= Amount

P= priciple

r=Rate of interest

n=Time period

Now it is given that,

P=$9710

r=5.9%

n=5

Then putting the values in the formula we get

[tex]A=9710(1+\dfrac{5.9}{100})^5[/tex]

A=$12932

Hence the total amount paid by Kate as a portion of interest will be $12932.

It would be cheaper to use the online store

Step-by-step explanation:

the physical store added up to $129.04 and the online store was $128.82.

It would cost less to purchase the items from the physical store.

The correct option is C.

A ratio or value that may be stated as a fraction of 100 is called a percentage. Moreover, it is indicated by the symbol "%."

To calculate the total cost for each store, we need to take into account the discounts, taxes, and shipping fees.

For the physical store:

Batteries: 2 packs x $5.99/pack = $11.98

Stereo: 1 system x $100.00/system = $100.00

CDs: 3 CDs x $7.95/CD = $23.85

Subtotal: $135.83

After the 10% discount: $135.83 - 10% = $122.25

Sales tax: $122.25 x 5% = $6.11

Total cost: $122.25 + $6.11 = $128.36

For the online store:

Batteries: 2 packs x $4.99/pack = $9.98

Stereo: 1 system x $90.00/system = $90.00

CDs: 3 CDs x $8.95/CD = $26.85

Subtotal: $126.83

After the $5.00 discount: $126.83 - $5.00 = $121.83

Shipping fee: $6.99

Total cost: $121.83 + $6.99 = $128.82

Therefore, it would cost less to purchase the items from the physical store.

Collinear points are the points which are formed on a straight line, whether they are close or far away.

If three or more points are collinear, then they form on the same line.

The slope of each pair of points will be same.

Here if A, B and C are collinear,

Slope of AB = Slope of BC

(4 - 0) / (7 - 9) = (q - 4) / (1 - 7)

-2 = (q - 4) / -6

q - 4 = 12

q = 16
