By definition of the derivative,

[tex]\displaystyle t'(x) = \lim_{h\to0} \frac{t(x+h) - t(x)}h[/tex]

[tex]\displaystyle t'(x) = \lim_{h\to0} \frac{\sqrt{-3(x+h)-7} - \sqrt{-3x-7}}h[/tex]

Rationalize the numerator by multiplying the fraction uniformly by its conjugate:

[tex]\displaystyle t'(x) = \lim_{h\to0} \frac{\sqrt{-3(x+h)-7} - \sqrt{-3x-7}}h \times \dfrac{\sqrt{-3(x+h)-7} + \sqrt{-3x - 7}}{\sqrt{-3(x+h)-7} + \sqrt{-3x - 7}}[/tex]

[tex]\displaystyle t'(x) = \lim_{h\to0} \frac{\left(\sqrt{-3(x+h)-7}\right)^2 - \left(\sqrt{-3x-7}\right)^2}{h \left(\sqrt{-3(x+h)-7} + \sqrt{-3x - 7}\right)}[/tex]

[tex]\displaystyle t'(x) = \lim_{h\to0} \frac{(-3(x+h)-7) - (-3x-7)}{h \left(\sqrt{-3(x+h)-7} + \sqrt{-3x - 7}\right)}[/tex]

[tex]\displaystyle t'(x) = \lim_{h\to0} \frac{-3h}{h \left(\sqrt{-3(x+h)-7} + \sqrt{-3x - 7}\right)}[/tex]

[tex]\displaystyle t'(x) = -3 \lim_{h\to0} \frac1{\sqrt{-3(x+h)-7} + \sqrt{-3x - 7}}[/tex]

The remaining limand is continuous at h = 0, so we can substitute h = 0 directly and get a limit/derivative of

[tex]\displaystyle t'(x) = -\frac3{\sqrt{-3(x+0)-7} + \sqrt{-3x - 7}} = \boxed{-\frac3{2\sqrt{-3x-7}}}[/tex]

Answer:

x = 12√3

y = 12

Step-by-step explanation:

=>> x/24 = perpendicular/hypotenuse

=>> x/24 = sin 60°

=>> x/24 = √3/2

=>> x = 24√3/2

=>> x = 12√3

now the value of y

=>> y/24 = cos 60°

=>> y/24 = 1/2

=>> y = 12

Mr. and Mrs. Bailey need to invest $2906.50 for eleven years so as to be able to contribute $7500 their son education.

Compound interest is given by:

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]

where A is the final amount, P is principal, r is the rate and n is the times compounded per year, t is the time

Given that t = 11, n = 1, r = 9% = 0.09, A = $7500 . Hence:

[tex]7500=P(1+\frac{0.09}{1} )^{1*11}\\\\P=\$2906.50[/tex]

Number of red marbles = 13

Number of green marbles = 12

Number of blue marbles = 5

Total Number of marbles = 13+12+5

Total Number of Marbles = 30 marbles

[tex]\sf \dashrightarrow \: probability \: of \: blue \: marble = \frac{5}{30} \\ \\ \sf \dashrightarrow \: probability \: of \: blue \: marble = \cancel \frac{5}{30} \\ \\ \sf \dashrightarrow \: probability \: of \: blue \: marble = \frac{1}{6} [/tex]

So, the probability of blue marbles would be ⅙ .

Answer:

1/6 chance of getting blue

Step-by-step explanation:

find your total (30) that will be your denominator

the number of blue marbles will be your numerator (5)

then simplify 5/30 to 1/6

The image point for the given rule and preimage is (6 - 8)

When we apply a rule T<a, b> to a preimage point (x, y) we get the image (x + a, y + b), so this is like a translation.

So if we apply the rule T<4, -1> to the preimage point (2, -7), the image will be:

(2 + 4, - 7 + (-1)) = (6 - 8)

Concluding, the image point is (6 - 8)

Answer:

an= a1 +(n-1)*4

Step-by-step explanation:

a1 = 1, a2 =5, a3 = 9, a4= 13,... an= ?

we see that each term is getting bigger so usually that will happen because of addition or multiplication-in our case add 4 to previous term

a1 = 1,

a2 = a1+(2-1) 4 = 1+4 = 5,

a3 = a1 + (3-1)*4 = a1+8 = 1 + 8 = 9,

a4= a1 + (4-1)*4 = a1 + 12 = 1+12= 13,

...

an= a1 +(n-1)*4

Answer:

13,260.22 mm²

Step-by-step explanation:

the area of the shaded region is the area of the larger circle minus the area of the smaller one

to find the area of the larger we will use half of 62 plus 41 as the radius:

Area (larger) = 3.14(72)²

= 16,277.76

Area (smaller) = 3.14(31)²

= 3,017.54

Area (shaded region) is 16277.76 - 3017.54 = 13,260.22 mm²

Using the together rate, it is found that it takes 144.5 hours to fill the empty pool when only the input pipe is open.

It is the sum of each separate rate.

In this problem:

Hence:

[tex]\frac{1}{x} + \frac{1}{x - 1} = \frac{1}{72}[/tex]

[tex]\frac{x - 1 + x}{x(x - 1)} = \frac{1}{72}[/tex]

[tex]x^2 - x = 144x - 72[/tex]

[tex]x^2 - 145x + 72 = 0[/tex]

Which is a quadratic equation with coefficients a = 1, b = -145, c = 72, hence:

[tex]\Delta = b^2 - 4ac = (-145)^2 - 4(1)(72) = 20737[/tex]

[tex]x_1 = \frac{145 + \sqrt{20737}}{2} = 144.5[/tex]

[tex]x_2 = \frac{145 - \sqrt{20737}}{2} = -0.5[/tex]

Time is a positive measure, hence, it takes 144.5 hours to fill the empty pool when only the input pipe is open.

The factors of the equation [tex]\rm x^3+x^2+x+1\\\\[/tex] are [tex]\rm (x^2 +1)(x +1)[/tex].

A factor is a number that divides another number leaving no remainder. In other words, if multiplying two whole numbers gives us a product, then the numbers we are multiplying are factors of the product because they are divisible by the product.

Given

The equation is;

[tex]\rm x^3+x^2+x+1[/tex]

The factors of the equation are given by;
