Answer:

The answer to your question is: letter D

Step-by-step explanation:

The interval graph is (5, 9] , open five, nine close. As an inequality this interval is:

5 < x ≤ 9

a) Letter A is incorrect because it suggests that two sections in the graph must be shaded and in this graph there is only one section shaded.

b) Letter B is incorrect because in the graph we observe that before 5 there must be a parenthesis because the point is open and the point in 9 is shaded so it must be follow by a ].

c) Letter c is alos incorrect because it suggests two sections shaded in the graph and it shows only one.

The volume of a right cone is 3525\piπ units^3

Greeley [361]

The height of the right cone given its volume and its diameter is 47 units.

<h3>What is the height?</h3>

A cone is a three-dimensional object that has a circular base and a vertex.

Height of the cone = Volume of a cone ÷ 1/3(πr²)

Where:

π = 22/7
r = radius = diameter / 2 = 30 / 2 = 15 units
h = height

3525π÷ (1/3 x π x 15²) = 47 units

Will Mark Brainlest Help pls

vampirchik [111]

Answer:

x=2,y=2

Step-by-step explanation:

3y-1 = 5

or, 3y = 5+1

or, y = 6/3

y = 2

2x+1 = 3y-1

or, 2x = 3×2-1-1

or, 2x = 4

or, x = 2

Calvin has $8.80 in pennies and nickels. If there are twice as many nickels as pennies, how many pennies does Calvin have? How m

Ray Of Light [21]

Let X = the number of pennies.

The number of nickels would be 2X

A penny is 0.01 and a nickel is 0.05

Now you have:

0.01x + 2(0.05x) = 8.80

Simplify:

0.01x + 0.10x = 8.80

Combine like terms:

0.11x = 8.80

Divide both sides by 0.11:

x = 8.80 / 0.11

x = 80

Pennies = X = 80 total pennies.

Nickels = 2x = 2 *80 = 160 nickels.

Write in standard form 2+4i over 1+i

Levart [38]

So hmm a conjugate, is pretty much just, the same binomial, but with a different sign in the middle, so, a + b, has a conjugate of a - b
or -a + b, has a conjugate of - a - b, or c - d, has a conjugate of c +d, and so on

anyway, the idea being, to "rationalize" the expression, namely, getting rid of the pesky radical in the denominator

so, we'll multiply the expression by 1, since anything times 1 is just itself

however, bear in mind, that 1, can be a/a, or b/b, or cheese/cheese, or anything/anything

so, we'll multiply the top and bottom of the fraction, by the conjugate of the denominator

anyhow, that said $\bf \cfrac{2+4i}{1+i}\cdot \cfrac{1-i}{1-i}\implies \cfrac{(2+4i)(1-i)}{(1+i)(1-i)}\implies \cfrac{2-2i+4i-4i^2}{1-i^2}\\\\
-----------------------------\\\\
\textit{recall that }i^2=-1\\\\
-----------------------------\\\\
 \cfrac{2-2i+4i-4(-1)}{1-(-1)}\implies \cfrac{2+2i+4}{2}\implies \cfrac{6+2i}{2}\implies \cfrac{6}{2}+\cfrac{2i}{2}
\\\\\\
\boxed{3+i}$
