A. 17
B. 32
C. 255
D. 544

Answers

Lets set the two numbers as 'a' and 'b'

Now let us set up some equations based on the information:

sum of two numbers 49 -->  a + b = 49difference of the two numbers is 15 --> a -b =15

Equations

 a + b = 49 -- equation 1

 a - b = 15 -- equation 2

Solve:

 (equation 1) + (equation 2)

    2a = 64

      a = 32 -- equation 3

 (equation 3)'s value of a into (equation 2)

  32 - b = 15

    b = 17

The products of 'a' and 'b' is 544

Answer/Step-by-step explanation:

The exponential function modeling the number of lions ⇒  the years passed since 2010 is appointed as

[tex]f(x)=2^1^+^2^x[/tex]

Well, If you have an question like what is exponential function?

Let's me tell you:

exponential functions which are expressed as some constant raised to the power of the argument called exponential function.

You might be asking how to find which function can model the given question..

[tex]\mathrm{Since \;2012 - 2010 = 2 \;and\; the\; number \;of\;lions = 32 =2^5}[/tex]

[tex]\mathrm{and \;2013 -2010 = 3\; and\; the\; number \;of\; lions\; =128 = 2^7}[/tex]

Hence, there is increment of 2 exponent as 1 year was changed.

Now, we have:

[tex]f(x)=2^2^x^+^a[/tex]

[tex]\mathrm{Thus,\; it\; increases \;every \;year \;by\; a \;ratio \;of \;2^(^2^)}[/tex]

[tex]\mathrm{Thus, \;in \;2011, \;it \;was \;2^(^5^) - 2^(^2^) = 2^(^3^)\; lions}[/tex]

[tex]\mathrm{In\; 2010, it\; was 2^(^3^) - 2^(^2^) = 2}[/tex]

Since Lions were introduced in the park in 2010, using f(x), it means;

[tex]x = 0, f(x) = 2[/tex]

[tex]x = 1, f(x) = 2^(^3^)[/tex]

[tex]x = 2, f(x) = 2^(^5^)[/tex]

[tex]x = 3, f(x) = 2^(^7^)[/tex]

Let's use the generic formula: y = ab^(x)

At x = 0 and y = 2, we have:

[tex]2 = a * b^(^0^)[/tex]

Thus,a = 2

At x = 1, y = 2^3

b = 8/2

b = 4

So the exponential equation is;

[tex]y = 2(4^(^x^))[/tex]

6. Quadrilateral ABCD has vertices at A(0,6), B(4, -1), C(-4,0) and D(-8,7). Prove that:

(a) ABCD is a rhombus using the distance formula

Answers

Step-by-step explanation:

AB = sqrt((4-0)^2 + (6-(-1))^2) = sqrt(16+49)=sqrt(65)

CD=sqrt((-8-(-4))^2 + (0-7)^2) = sqrt(49+16)=sqrt(65)

Therefore, sides AB and CD are congruent because they have the same measure.

BC = sqrt((4-(-4)^2 + (-1-0)^2) = sqrt(64+1)=sqrt(65)

AD=sqrt((0-(-8))^2 + (7-6)^2) = sqrt(64+1)=sqrt(65)

Therefore, sides BC and AD were congruent because they have the same measure.

This means ABCD is a parallelogram because there are two pairs of opposite congruent sides.

Now, notice that AB=BC, meaning sides AB and BC are congruent.

This means that parallelogram ABCD has one pair of consecutive congruent sides, and is thus a rhombus.

Two​ trains, Train A and Train​ B, weigh a total of 479 tons. Train A is heavier than Train B. The difference of their weights is 357 tons. What is the weight of each​ train?

Answers

Answer: Train A weighs 418 tons and Train B weighs 61 tons

Step-by-step explanation:

Let a represent the weight of Train A, and let b represent the weight of Train B.

We can set up a system of equations.

a + b = 479

a - b = 357 ( as we are given that a is heavier than b )

We can add the two equations:

a + b + a - b = 479 + 357

Combine like terms (which cancels out the b):

2a = 836

Divide both sides by 2:

a = 418

We can plug this back into the first equation:

418 + b = 479

Subtract 418 from both sides:

b = 61

A+B= 479tons
Thus representing the total weight of train A and B
Let make train A =A and train B = B
It says the difference of their weight is 357tons
I am going to devise equations out of it

357+A=B……equation 1
A+B=479……..equation 2

Since B is the subject of equation 1 already we would put in into equation 2

A+(357+A)=479
2A=479-357. 2A=122

Divide both side by 2
2A/2=122/2
A=61

Train As weight is 61
And we Can find Train Bs weight as

357+61=B

B=418

) 6 students are going on a field trip and 35 students are staying at school. What is the ratio of
the number of students who are going on the field trip to the total number of students?

Answers

Answer:

6:41

Step-by-step explanation:

We know that the number of students going on the field trip is 6.

To find the total number of students, add the number of students going on the trip and the number of students staying at the school: 6 + 35 = 41

So the ratio of the number of students going on the field trip to the total number of students is 6:41
