Answer:

z = 58

Step-by-step explanation:

Since SU is a midsegment of QRT, the length of SU is one-half the length of RQ.

[tex] \frac{1}{2} (z - 40) = z - 49[/tex]

[tex]z - 40 = 2z - 98[/tex]

Answer:

x = 3 ± [tex]\frac{\sqrt{10} }{-2}[/tex]

Step-by-step explanation:

To find the roots of this equation, we can either use facotring or the quadratic formula. Because this equation isn't facotrable, we will use the quadratic formula to solve it

-2[tex]x^2[/tex] + 12x - 13 = 0

x = [tex]\frac{-12 +- \sqrt{12^2 - 4(-13)(-2)} }{-4}[/tex]

x = [tex]\frac{-12 +- \sqrt{144-104} }{-4}[/tex]

x = [tex]-\frac{-12 +- \sqrt{40} }{-4}[/tex]

x = 3 ± [tex]\frac{\sqrt{10} }{-2}[/tex]

Answer:

base = 3

Step-by-step explanation:

The area of triangle is calculated using the following formula:

1/2*b*h (b: base, h: height)

The area and height is given, to find the base we can make the following equation:

1/2*b*9 = 54

9b/2 = 54 multiply both sides by 2

9b = 27 divide both sides by 9

b = 3

Answer:

the area for

a=16pi or 50.26548...

b=64pi or 201.061329...

c= 169pi or 530.929158...

d=100pi or 314.159265

d is 19.7392088... or 6.25pi times greater than a

Step-by-step explanation:

the decimal values are more accurate for the d is greater than circle a

so you start with a=4 in radius then b=a+4, c=b+5, d=c-3

then solve the equation a=4, b=8, c=13, d=10

then you solve for the area using the formula radius squared pi

getting the answers above

as for the second answer you would divide d to a getting the amount of times more above for circle d and circle a

An expression is defined as a set of numbers, variables, and mathematical operations. The value(s) for which the rational expression (10w−5)/(2w²+11w+5) is undefined is -1/2 and -5.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The value for which the function will not be defined is the value of w which will make the denominator of the rational function zero. This values can be found by factorizing the denominator of the function. Therefore,

2w² + 11w + 5 = 0

2w² + 10w + 1w + 5 = 0

2w(w+5) + 1(w+5) = 0

(2w+1)(w+5) = 0

w = -1/2 , -5

Hence, the value(s) for which the rational expression (10w−5)/(2w²+11w+5) is undefined is -1/2 and -5.

Answer:

Step-by-step explanation:

At Box-r-us, they have 3*4*5=60 different boxes.

At Ship to go they have 6*2*7=84 different boxes

Therefore the number of boxes that box r us has is less than the number of boxes that Ship to go has.

The value of n is 3, value of m is 2 and the value de m + n + p is -2.

In this question we must analyze a null polynomial and determine three unknown variables. A null polynomial is those whose coefficients are equal to zero.

Therefore, we must resolve the following system of linear equations:

3 · n - 9 = 0   (1)

m - 2 = 0       (2)

p + 7 = 0       (3)

The solution of this system of linear equations is: n = 3, m = 2, p = -7. The value of n is 3, value of m is 2 and the value de m + n + p is -2. [tex]\blacksquare[/tex]

Answer:

Step-by-step explanation:

We want to model the growth of a population of bacteria using an exponential function. We find it convenient to use an "exact" exponential function that relies directly on the numbers given in the problem statement. That function has the form ...

  p(t) = (initial population) × (growth factor)^(t/(growth period))

where the "growth factor" is the multiplying factor of the population in period "growth period."

__

Here, the "growth factor" is 4800/4000 = 1.2, and the corresponding "growth period" is 5 hours. Then the population function can be ...

  p(t) = 4000×1.2^(t/5)

__

The population after 15 hours is ...

  p(15) = 4000×1.2^(15/3) = 4000×1.728

  p(15) = 6912

__

To change this to the form ae^(kt), we find the value of k to be ...

  k = ln(1.2^(1/5)) = ln(1.2)/5 ≈ 0.036463

Then the desired form of the function for p is ...

  p(t) = 4000·e^(0.036463t)

_____

Additional comment

In the form p=ae^(kt) the value of k is often rounded to 3 or 4 decimal places. We believe that best accuracy is obtained if k has at least the number of significant digits expected in the answer. Here, the population of almost 7000 has 4 significant digits, so we choose to express k to 5 significant figures. That still gives a small error relative to the first formula that is only "corrected" by rounding the result to an integer.

Jonathan will need a warping paper of 420.78m^2

Data;

To find the amount of warping paper used, we can use the formula of surface area of an equilateral triangle since the triangle used here is an equilateral triangle.

[tex]Surface Area = base area + \frac{1}{2}(perimeter * slant height)[/tex]

Let's calculate the base area and perimeter of the triangle.

base area of an equilateral triangle is given as

[tex]B.A = \frac{\sqrt{3} }{4} a^2[/tex]

Let's substitute the value and solve

[tex]B.A = \frac{\sqrt{3} }{4} a^2\\B.A = \frac{\sqrt{3} }{4}*10.39^2\\B.A = 46.74m^2[/tex]

The base area is 46.74m^2

Let's calculate the perimeter of the triangle

[tex]P = 3a\\[/tex]

Substitute the value into the equation and solve

[tex]P = 3a \\P = 3 * 10.39\\P = 31.17m^2[/tex]

We can proceed to substitute the values of the base area and perimeter of the triangle into the formula of the surface area of an equilateral triangle.

[tex]S.A = base area + \frac{1}{2}(perimeter * slant height)\\S.A = 46.74 + \frac{1}{2}(31.17*12)\\S.A = 46.74 + 374.04\\S.A = 420.78m^2[/tex]

The surface area of the equilateral triangle is 420.78m^2
