How do I solve for x? (the picture has the problem)

Mathematics

schepotkina [342]2 years ago

Step-by-step explanation:

imagine this right-angled triangle is the sine and cosine scenario in a circle. just turn it in your mind or on the paper until it looks like this.

the point with the 36° angle is the center of this circle.

x is the radius of the circle, that is under 36° connecting the center of the circle with the arc of the circle.

17 is the cosine of the angle multiplied by the radius (as the standard cosine function is normed for the standard circle with radius 1).

and the other leg is the sine of the angle multiplied by the radius (this is FYI, we don't need that for the solution here).

so,

17 = cos(36) × x

x = 17/cos(36) = 21.01315562...

Answer:

x = 21.013155617496

Step-by-step explanation:

we have a right triangle then ,

\cos \left( 36\right)  =\frac{17}{x}

Then

x=\frac{17}{\cos \left( 36\right)  } = 21.013155617496

Then

x ≈ 21

A new shopping mall records 120 total shoppers on their first day of business. Each day after that, the number of shoppers is 10
Marta_Voda [28]

Answer:

1138

Step-by-step explanation:

From the information given:

We can represent it perfectly in an exponential form:

m  = p(q)^x

where;

p = initial value = 120

q = base of the exponential form

q = 1 + r

here; r = rate in decimal = 10% = 0.1

Then q can now be = 1 + 0.1 = 1.1

Replacing it into the exponential form, we get:

m = 120(1.1)^x

where;

x = number of days and m = number of shoppers

Thus:

For the first day:

m = 120(1.1)^x

m = 120

For the second day:

m = 120(1.1)^1

m = 132

For the third day:

m = 120(1.1)^2

m = 145.2

For the fourth day

m = 120(1.1)^3

m = 159.72

For the  fifth-day

m = 120(1.1)^4

m = 175.692

For the sixth-day

m = 120(1.1)^5

m = 193.2612

For the seventh-day

m = 120(1.1)^6

m = 212.58732

Thus; the total numbers of shoppers for the first 7 days is:

= 120+ 132 + 145.2 + 159.72 + 175.692+193.2612+212.58732

= 1138.46052

≅ 1138

The flagpole is 20 ft high and casts an 8 foot shadow, the oak tree casts a 12 foot shadow. How tall is the oak tree
Fudgin [204]
Answer: 4.8 ft

To answer this question you need to know how much shadow: actual height ratio. Flagpole is having 8 ft shadow with 20 ft actual height. The ratio should be= 8 ft: 20 ft= 0.4

Then multiply the ratio with the oak tree shadow. The equation would be:
0.4 x 12 ft= 4.8 ft
