Answer:

The third one because it fails the vertical line test.

A vertical line would not touch the line more than once at any point on the graph, if it were a function.

Answer:

Step-by-step explanation:

Total amount of faces of object = 6

Surface area = length x height

2(4*10) + 2(10*17) + 2(4*17)

=2(40) + 2(170) + 2(68)

= 80 + 340 + 136

= 556cm^2

Answer the 21st one. this question is from the chapter exponents and powers.

Mila [183]

Answer: 729

Step-by-step explanation:

Move items with negative exponents from numerator to denominator or vice versa and change sign of exponent. Factorize composite numbers, say 10^3 = 2^3 × 5^3 and 81 = 3^4. Combine factors with same base, adding exponents. Cancel factors appearing in both numerator and denominator, subtracting exponents.

5^-3×6^-5×81×4/(3^-7×10^-3)

= 3^7×10^3×81×4/(5^3×6^5)

= 3^7×2^3×5^3×3^4×2^2/(5^3×2^5×3^5)

= 2^5×3^11×5^3/(2^5×3^5×5^3)

= 3^6

= 729

A box of popcorn weighs 15/16 pounds. The box contains 1/3 buttered popcorn and 2/3 cheesy popcorn. How much does the cheesy pop

ella [17]

we know that

To find the weight of the cheesy popcorn Multiply the total weight by the proportion of the cheesy popcorn

$\frac{15}{16} *\frac{2}{3}=\frac{30}{48}=\frac{5}{8}\ pounds$

therefore

<u>the answer is</u>

the weight of the cheesy popcorn is $\frac{5}{8}\ pounds$

Answer:

Step-by-step explanation:

This is a related rates problem from calculus using implicit differentiation. The main equation is Pythagorean's Theorem. Basically, what we are looking for is $\frac{dx}{dt}$ when y = 6 and $\frac{dy}{dt}=-2$ .

The equation for Pythagorean's Theorem is

$x^2+y^2=c^2$ where x and y are the legs and c is the hypotenuse. The length of the hypotenuse is 10, so when we find the derivative of this function with respect to time, and using implicit differentiation, we get:

$2x\frac{dx}{dt}+2y\frac{dy}{dt}=0$ and divide everything by 2 to simplify:

$x\frac{dx}{dt}+y\frac{dy}{dt}=0$ . Looking at that equation, it looks like we need a value for x, y, $\frac{dx}{dt}$ and $\frac{dy}{dt}$ .

Since we are looking for $\frac{dx}{dt}$ , that can be our only unknown and everything else has to have a value. So what do we know?

If we construct a right triangle with 10 as the hypotenuse and use 6 for y, we can solve for x (which is the only unknown we have, actually). Using Pythagorean's Theorem to solve for x:

$x^2+6^2=10^2$ and
