Find the area of the figure with Heron’s formula

Answer:

you just have to add 5x+120=180 , since all the angles should add to 180. Doing that, and x will be 12.

Step-by-step explanation:

[tex]180 - 60 - 60 = 5x \\ 5x = 60 \\ x = 12[/tex]

Five days later the wool blanket would cost $ 1,400,000.

Given that in Zimbabwe the rate of inflation hit 90 sextillion percent in 2009, with prices increasing tenfold every day, to determine, at that rate, how much would a $ 14 wool blanket cost five days later, the following calculation must be performed:

Future price = (current price) * (inflation rate) ^ number of days

X = 14 x 10 ^ 5

X = 14 x 100,000

X = 1,400,000

Therefore, five days later the wool blanket would cost $ 1,400,000.

The sale price of suit will be $196.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

A $280 suit is marked down by 30%.

Now,

Since, A $280 suit is marked down by 30%.

Hence, The sale price = $280 - 30% of 280

                                  = $280 - 30/100 × 280

                                  = $280 - $84

                                  = $196

Thus, The sale price of suit = $196.

Answer:

Step-by-step explanation:

Using the chain rule

Given

y = f(g(x)), then

[tex]\frac{dy}{dx}[/tex] = f'(g(x))  × g'(x) ← chain rule

and the standard derivatives

[tex]\frac{d}{dx}[/tex] ([tex]log_{a}[/tex] x ) = [tex]\frac{1}{xlna}[/tex] , [tex]\frac{d}{dx}[/tex](lnx) = [tex]\frac{1}{x}[/tex]

(a)

Given

y = [tex]log_{a}[/tex][tex]\sqrt{(1+x)}[/tex]

[tex]\frac{dy}{dx}[/tex] = [tex]\frac{1}{lna\sqrt{(1+x)} }[/tex] × [tex]\frac{d}{dx}[/tex] ([tex](1+x)^{\frac{1}{2} }[/tex]

   = [tex]\frac{1}{lna\sqrt{(1+x)} }[/tex] × [tex]\frac{1}{2}[/tex] [tex](1+x)^{-\frac{1}{2} }[/tex] × [tex]\frac{d}{dx}[/tex] (1 + x)

   = [tex]\frac{1}{lna\sqrt{(1+x)} }[/tex] × [tex]\frac{1}{2\sqrt{(1+x)} }[/tex] × 1

   = [tex]\frac{1}{2lna(1+x)}[/tex]

   = [tex]\frac{1}{(1+x)lna^2}[/tex]

(b)

Given

y = ln sinx

[tex]\frac{dy}{dx}[/tex] = [tex]\frac{1}{sinx}[/tex] × [tex]\frac{d}{dx}[/tex](sinx)

   = [tex]\frac{1}{sinx}[/tex] × cosx

   = [tex]\frac{cosx}{sinx}[/tex]

D. x = 2, y = 2

Step-by-step explanation:

Show Solution. Start by writing the equation of the parabola in standard form. The standard form that applies to the given equation is (x−h)2=4p(y−k) ( x − h ) 2 = 4 p ( y − k ) . Thus, the axis of symmetry is parallel to the y-axis.

Step-by-step explanation:

Volume of water in sphere is 2,143.57 cm³

Radius of sphere = 8 cm

Value of π = 3.14

Volume of water in sphere

Volume of sphere = (4/3)πr³

Volume of water in sphere = (4/3)(3.14)(8)³

Volume of water in sphere = (4/3)(3.14)(512)

Volume of water in sphere = 2,143.57 cm³

Answer:

Each day, you record the high temperature* (you don't necessarily need to say that it is for a science project). On Day 1, it was 4* less than Day 10**. It hit 62* F on Day 10. What was the high temperature on Day 1?

Because we know that on Day 1, the temperature was 4* less than on Day 10, and the high temperature on Day 10 was 62*, the high temperature on Day 1 was therefore 58*. Because 62 - 4 = 58.

Step-by-step explanation:

*You don't necessarily need to say that it was for a science project.

**The information for Day 4 is irrelevant too because we are not given the temperature for Day 4, therefore it does not help us find the answer.

Answer:

12

Step-by-step explanation:

So if the difference between the two number is 16 and the distance between the two numbers in the ratio is 4, that means the real numbers are 4 times greater than the ratio (because 4 * 4 = 16).

This means that you can multiply both sides of the ratio by 4 to get the two numbers 3: 7 --> 3*4: 7 * 4 --> 12: 28.

This means that the smaller number is 12.
