10⁴ is 10,000 written as a power with a base of 10

Answer:

10^3

Step-by-step explanation:

10 has a decimal point at the end of it. You have to jump 3 places to get 10,000. So, the answer would be 10 to the third power, ,or 10^3

Answer:

  a) n(A∪B) = 20

  b) n(A) = 31

Step-by-step explanation:

The relevant formula is ...

  n(A∪B) = n(A) +n(B) -n(A∩B)

__

a) n(A∪B) = 5 +18 -3 = 20

b) 32 = n(A) +14 -13   ⇒   n(A) = 31

Answer:

Answer:

20,600,000,000

Step-by-step explanation:

When writing a number in standard notation from scientific notation, counting decimal places is important. In this case, the exponent of 10 is 10. That means the decimal place must be moved 10 places; since it is positive the decimal place should be moved to the right. Finally, fill any empty spaces when moving the decimal point with zeros.

The cost of Ferry ticket is $9.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, the train ticket costs $45.

Let the cost of Ferry ticket be x.

The train ticket costs 5 times as much as the Ferry ticket.

Now, the cost of train ticket =5x

45=5x

x=$9

Therefore, the cost of Ferry ticket is $9.

Answer:

equation is y= 50 + 3f

57F

15 Minutes

Step-by-step explanation:

a) the equation above because 50 is the starting temp and every 3 minutes is another degree F

b) if the temp rises 1 degree every 3 minutes, then 21/3 is 7 degrees hotter plus 50, which is 57 F.

c) if 50 plus 3f is the equation, then 3 times 5 will make 55 degrees. After 15 minutes, the temp will be 55 F.

Answer:

71. 19  72. 100  73. 9  74.1  75. 90  76. 4

Step-by-step explanation:

#71.

Start with 2b-a

Plug in the given numbers where the variables are.

Now the equation is 2(12) - 5

Solve 2(12) - 5

2(12) = 24      24 - 5 = 19

#72.

Start with d(ab-c)

Plug in the given numbers where the variables are.

Now the equation is 2((5×12) - 10)

Solve in the parenthesis first.

5×12= 60    60-10=50    2(50)= 100

#73.

Start with 3+ [tex]\frac{b}{d}[/tex]

Plug in the given numbers where the variables are.

Now the equation is 3+ [tex]\frac{12}{2}[/tex]

Solve.

[tex]\frac{12}{2}[/tex] = 6    3+6 = 9

#74.

Start with [tex]\frac{4a}{b+4d}[/tex]

Plug in the given numbers where the variables are.

Now the equation is [tex]\frac{4(5)}{12+(4x2)}[/tex]

Solve.

4(5)= 20    

(4×2)= 8    12+8= 20

Now the fraction is  [tex]\frac{20}{20}[/tex] = 1

#75.

Start with 2a² - c

Plug in the given numbers where the variables are.

Now the equation is 2(5)² - 10

Solve 2(5) = 10      10² = 100  100-10= 90

#76.

Start with b - c + d

Plug in the given numbers where the variables are.

Now the equation is 12 - 10 + 2

Solve.

12 - 10 = 2     2 + 2 = 4

Let start with some basic theory of quadratics

If  f(x)=ax2+bx+c  a,b,c ∈R  a≠0    f(x)=ax2+bx+c  a,b,c ∈R  a≠0  has   2    2   roots   r1    r1  and   r2    r2  than it can take the form f(x)=a(x−r1)(x−r2).f(x)=a(x−r1)(x−r2).

The maximum or minimum value of  f(x)    f(x)   is   M=−(b2–4ac)4a  M=−(b2–4ac)4a

If   a>0    a>0  then  M    M  is the minimum value and if   a<0    a<0   then   M    M  is the maximum value.

Lets go now to the question

Since  2    2  and   7    7  are the roots our function will be  f(x)=a(x−2)(x−7),  a∈R  f(x)=a(x−2)(x−7),  a∈R

so   f(x)=a(x2

Answer:

W = 1.06 MJ

Step-by-step explanation:

- We will use differential calculus to solve this problem.

- Make a differential volume of water in the tank with thickness dx. We see as we traverse up or down the differential volume of water the side length is always constant, hence, its always 8.

- As for the width of the part w we see that it varies as we move up and down the differential element. We will draw a rectangle whose base axis is x and vertical axis is y. we will find the equation of the slant line that comes out to be y = 0.5*x. And the width spans towards both of the sides its going to be 2*y = x.

If the vectors [tex]\{\mathbf v_1,\mathbf v_2,\ldots,\mathbf v_p\}[/tex] span [tex]\mathbb R^n[/tex], then any vector [tex]\mathbf x\in\mathbb R^n[/tex] can be expressed as a linear combination of these vectors. This means there exist scalars [tex]\{c_1,c_2,\ldots,c_p\}[/tex] such that

[tex]\mathbf x = c_1\mathbf v_1 + c_2\mathbf v_2 + \cdots + c_p\mathbf v_p[/tex]

Since T is a linear transformation, we have for all x,

[tex]T(\mathbf x) = T(c_1\mathbf v_1 + c_2\mathbf v_2 + \cdots + c_p\mathbf v_p) \\\\ T(\mathbf x) = c_1T(\mathbf v_1) + c_2T(\mathbf v_2) + \cdots + c_pT(\mathbf v_p) \\\\ T(\mathbf x) = \mathbf 0 + \mathbf 0 + \cdots + \mathbf 0 = \mathbf 0[/tex]
