[tex]V=\pi r^{2}h[/tex]

[tex]V= A \frac{r}{2} -\pi r^{2} =1890 *\frac{9}{2} -\pi *9^{3} = 6214.77896[/tex]

Answer:

0.8

Step-by-step explanation:

I'm  just writing this

The answer is

for parallel : x-4=0

for perpendicular: y+4=0

The slope-intercept form is written as y = mx+b, where m is the slope and b is the y-intercept (the point where the line crosses the y-axis). It's usually easy to graph a line using y=mx+b.

Given line: x=-7

The slope of line x=7 is infinite

The equation of line passing through point (4,-4) and having slope infinite is

0.y+x=-7

So, 0.y= 4

hence, x=4

slope intercept form

x-4=0

Now, for perpendicular lines:

swap the coefficients on x and y with negative sign of x in x=-7

This is a vertical line, so the perpendicular line will be a horizontal line of the form y=b.

Since we are given that the line should pass through the point (4,−4), then the equation of the line is y=−4.

By taking the product between the rate and the time, we will see that he does not finish the book.

We know that he can read 5 pages in 15 minutes. Then in one hour he can read 4 times that: 4*5 pages = 20 pages.

We conclude that Carter reads 20 pages per day, then, if he reads for 14 hours, then he reads a total of:

20*14 = 280

So he will read 280 pages in these 14 hours, which means that he will not finish the book.

please read the explanation... it always helps!!

Step-by-step explanation:

alrighty..

so the total budget is 1200, and we want to know how much is 62% of that

so you follow the percent formula as follows:

1200/100= 12 --> 12 x 62= 744 (which is the answer!)

For the exponential expression, [tex]16^{1/4}[/tex] the simplified value is 2.

First, we need to remember a rule for exponential expressions, it says that:

[tex]x^{1/n} = \sqrt[n]{x}[/tex]

Then we can rewrite the given exponential expression as:

[tex]16^{1/4} =\sqrt[4]{16}[/tex]

So, we just need to find a number that when multiplied by itself 4 times, is equal to 16.

We know that:

2*2 = 4

Then:

2*2*2*2 = 2⁴ = 4*4 = 16

Then we can conclude that:

[tex]16^{1/4} =\sqrt[4]{16} = 2[/tex]

So the simplified value of the exponential expression is 2.

The roots of this equation equation are:

x1 = 4

x2 = 8

This sentence given in the statement of this question is: Equation of the Second Degree. There are a few ways to solve it, but let's calculate by the factorization method.

Equation given: x² - 12x + 36 = 4

x² - 12x + 36 = 4

12x ➯ 2x . x6

36 ➯ 6²

x² - 2x . x6 + 6²

( x - 6 )² = 4

( x - 6 )² = 4

x - 6 = ±√4

x - 6 = ±2

x - 6 = ±2

x - 6 = -2

x - 6 = +2

x - 6 = -2

x = -2 + 6

x = 4

x - 6 = +2

x = 2 + 6

x = 8

Therefore, the correct results of this equation, will be:

x1 = 4

x2 = 8

Answer:

slope = - 1

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given

x + y = - 7 ( subtract x from both sides )

y = - x - 7 ← in slope- intercept form

with slope m = - 1

Parallel lines have equal slopes

then the slope of a line parallel to it is - 1

The population (number of bacteria in the colony), 950 hours from that time, will be 260 bacteria

From the question, we are to determine what the population will be after 950 hours

From the given information,

The number of bacteria in a colony doubles every 475 hours

The current population is 65 bacteria

∴ After 475 hours, the new population will be 2 × 65 bacteria

New population after 475 hours = 130 bacteria

After another 475 hours (that is, 950 hours from the initial time),

The population will be 2 × 130 bacteria = 260 bacteria

Hence, the population, 950 hours from that time, will be 260 bacteria
