Answers

Answer 1

Answer:

Part A:

given that cos β = 3/5

that means the base line is 3 and the hypotenuse is 5

Note that, The base line 3 is adjacent to β and opposite to α.

Sin α = opposite / adjacent

sin α = 3 /5

Part B:

α and β are complementary angles

Phillipe has 320 pieces of
candy that he wants to
hand out to the class. If he
has 27 classmates, how
many pieces will be left
over after giving everyone
an equal amount?
25

Answers

The number of candies that will be left over after giving everyone an equal amount is equal to 23.

Given the following data:

Total number of candy = 320 piecesNumber of classmates = 27 classmates

To calculate the number of candies that will be left over after giving everyone an equal amount:

In this exercise, you're required to determine the number of candies Phillipe would have as left over after giving everyone in his class an equal amount of candies.

How to solve this word problem.

Thus, we would find the number of times 27 would divide 320 without any remainder.

[tex]\frac{320}{27} = 11 \frac{23}{27} [/tex]

From the mixed fraction, we can deduce that the remainder is 23.

Therefore, the number of candies that will be left over after giving everyone an equal amount is equal to 23.

Identify the cross section that results from slicing the three-dimensional figure.
A)
pyramid
B)
prism
C)
square
D)
triangle

Answers

Answer: C) Square

Explanation:

You have the correct answer. The blue plane is basically a knife that cuts the pyramid into two pieces. The top portion is a smaller similar pyramid (same shape, smaller size). The bottom portion is a pyramidal frustum.

Where the cut happens in the blue plane, a square forms. This square is the base of the upper pyramid and the roof of the frustum.

We can think of the blue stuff like water. Then allow that water to freeze to form a block of ice. Then carefully slide the block of ice upward and there should be a square hole in the center. So this is another way to see how we have a square cross section. The square cross section is due to the pyramid's base being a square. This means that if we had say a hexagonal base, then the cross section would be hexagonal.

All of this only applies if the cutting plane is parallel to the base of the pyramid.

A string is wound symmetrically Around a circular rod The string goes exactly 5 times around the rod The circumference Of the rod is 4cm And its length is 15cm Find the length of the string in cm​

Answers

The length of the string in cm is; 20 cm

Circumference of a circle

We are told that the string is wound symmetrically around a circular rod.

Now, the circumference of the rod is 4 cm and length is 15 cm.

Now, circumference is also the length of a circle. Thus, one wound of the string will be equal to the circumference of the rod.

Thus, one wound = 4 cm

Since the string makes 5 turns about the rod, then;

Length of string = 5 × 4 = 20 cm

The area of a rectangle is 20 cm². The height is 4 cm longer than thrice the width.
Find the width of the rectangle.

cm

Answers

Answer:

width = 2 cm

Step-by-step explanation:

are of rectangle is equal to length times width

x is the width, then length is 3x + 4

so x(3x + 4) = 20

3x^2 + 4x = 20

3x^2 + 4x - 20 = 0

The formula to solve a quadratic equation of the form ax^2 + bx + c = 0 is equal to x = [-b +/-√(b^2 - 4ac)]/2a

so a = 3

    b = 4

    c = -20

substitute in the formula

x = [-4 +/-√(4^2 - 4(3)(-20))]/2(3)

x = [-4 +/- √(16 + 240)]/6

x = [-4 +/- 16]/6

x1 = (-4 + 16)/6 = 2

x2 = (-4 - 16)/6 = -20/6

since the width can't be a negative number, x2 is not the right answer

so x = 2

or, x - 3x + 3x = 6 - 6

-3x and 3x will cancel out and also 6 and -6 will also get cancelled out.

Which of the following graphs could represent a quartic function?
A.
B.
D.
A. Graph A
Ο Ο Ο
B. Graph B
C. Graph C
D. Graph D

Answers

Answer:

D

Step-by-step explanation:

a quartic function is a polynomial of the 4th degree. that means that in the function expression the highest exponent of a term of x is 4.

y = ax⁴ + bx³ + cx² + dx + e

with a not 0.

the degree of a polynomial expression defines also how many zeroes (x values that create y = 0, that means points where the graph intersects the x-axis) there are.

a function has as many zeroes as the degree of the polynomial.

so, we are looking for potentially 4 zeroes.

the only graph that fulfills that is D.

the left "touch" of the graph on the x-axis counts for 2 (but equal) zeroes.

you can always test by virtually shifting the graph up or down and see, what are the max. x-axis intersections you can create.

if shifting D down a little bit you see, that this left "touch" turns into 2 intersections.

the same would apply for a "bend" or turn in the graph that does not even touch the x-axis.

if the original graph has not enough real x-axis intersections, it means that the remaining zeroes are then "imaginary" complex numbers (based on the sqrt(-1) = i).

a polynomial of the nth degree, must have n zeroes.

as a consequence it must have n-1 turns (even if the corresponding curve segments don't intersect with the x-axis in the real number space).

Shawn drew a number line that went from - 10 to 10 and used it to compare

Answers

ANSWER

The integer -1000000 is not going to be in the graph.

EXPLANATION

First take one million. Add 5 to it and then multiply it by 3. After that take the

square root of 7 and add it to 120. Now angle ABC is 41*. So then you multiply

42* by 5. After that divide -6*F by -30*C  and take the square root of the

quotient and find the calculus of it. after that multiply it by infinity and then pi.

Once done add it all together. After that take 2 million and convert to

negative 2 million. Then divide it all together.

And that is how you find out that -1000000 is not going to be in the graph.
