QRST IS AN ISOSCELES TRAPEZOID FIND YZ

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:

19 folders

Step-by-step explanation:

8 + 6 + 5 = 19

Answer:

a)12/20

because 5 × 4 = 20 so, 3 also needs to multiply by 4

b)5/6

because 30 ÷ 6 = 5, and 6 × 5 = 30,so, 25 needs to ÷ with 5

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]

   = cotx

Answer:

105

160

150

Step-by-step explanation:

This is just simple subtraction.

180-75=105

180-20=160

180-30=150

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.

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:

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.

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.
