Answer:

5 and -8

Step-by-step explanation:

One number must be negative since the product of the 2 number is negative (5 x -8 = -40). They both cannot be negative, if they were the product would then be positive. The negative number must have a absolute value that is larger than the positive, the negative numbers distance from 0 must be larger than the positive, -8 has a distance of 8 and 5 has a distance of 5. The sum of the two numbers is

=5 + (-8)

=5 - 8  

= -3

Answer:

x = 0, y = 3

Step-by-step explanation:

When using graphing to solve a system of equations, the intersection point is the solution. Most points on a graph follow a certain way of writing them and it looks like this: (x, y).

Here, the coordinates of the intersection point is: (0, 3). Thus the solution would be:

(x, y)

(0, 3)

x = 0, y = 3

Answer:

Stocks = 4500

Bonds = 9500

Step-by-step explanation:

Given that:

Total interest earned = 1257

Interest rate of stock = 2.6% = 0.026

Interest rate on bond = 12% = 0.12

Total amount invested = 14000

Let amount invested in stock = x

Amount invested in bond = 14000 - x

Using the relation :

Principal * rate * time

Stocks :

x * 0.026 = 0.026x

Bonds:

(14000 - x) * 0.12 = 1680 - 0.12x

0.026x + 1680 - 0.12x = 1257

−0.094x = 1257 - 1680

-0.094x = - 423

x = 423 / 0.094

= 4500

14000 - x = 14000 - 4500 = 9500

Stocks = 4500

Bonds = 9500

Answer:

Answer:

It depends on how much percent the test is worth and everything you might be missing but more than likely no you'd have to do really well on the test and a few assignments . There's a way you can calculate your grade with whatever you might be missing and the grade you're trying to get in the class.

you'd have to divide your grade in each category by 100 then multiple it by the percentage and add everything together for example:

Homework is 20% of a grade . I have a 90 in the homework category . 90/100 times 20 which will give me 18 then put the 18 over 20. 18/20

Projects are 30% of a grade. You have a 50 out of 80 do 50/80x30. which is 18.75 out of 30.

Final is 50% lets say you get a perfect score on the final meaning you get 50 points.

add 18+18.75+50= 86.75

add 20+30+50=100

you'd make a 86.75 in the class so a B. hopefully this helps . So if you need 14 points you should go to your assignments/tests and it should say how much there worth.

Answer:

(C) x^3+11x^2+34x+24

Step-by-step explanation:

The volume of a rectangular prism is V=lwh

x+4=L

x+1=W

x+6=H

Thus:

(x+4)(x+1)(x+6)

(x^2+5x+4)(x+6)

x^3+5x^2+4x+6x^2+30x+24

x^3+11x^2+34x+24

Therefore, the correct answer is (C) x^3+11x^2+34x+24

this was a hard question and I do not understand it.

Answer:

C The magnitude is 7.94, and the direction angle is N 49.91° E.

magnitude formula: sqrt x^2+y^2

                                 sqrt 6^2+5.2^2

                                 7.94

direction angle: tan^-1(x/y)

                          tan^-1(6/5.2)

                          49.91                      (convert radians to degrees)

The direction angle and magnitude of the position vector are 34 degrees and 7.93 respectively.

The direction of a vector is the orientation of the vector, that is the angle it makes with the x- axis.

If  position vector v = <a, b>, then the magnitude is given by

[tex]|v| = \sqrt{a^{2}+b^{2} }[/tex]

If θ is the angle formed with the x- axis or y axis  ,then direction is given by

θ = [tex]tan^{-1}\frac{b}{a}[/tex]

According to the given question

We have

Position vector (6, 5.2)

So, the magnitude of the position vector = [tex]\sqrt{6^{2}+(5.2)^{2} }[/tex] = [tex]\sqrt{36+27.04}[/tex]

= [tex]\sqrt{63.04} =7.93[/tex]

Now, the direction angle of the vector is given by

[tex]tan\alpha =\frac{6}{5.2} \\ tan\alpha =1.15\\\alpha =tan^{-1} (1.5) = 56degrees.[/tex]

Therefore,

θ = 90 -56 = 34degrees.

Hence, the direction angle and magnitude of the position vector are 34degrees and 7.93 respectively.

Step-by-step explanation:

I like to work these considering the difference in ratio units.

The age ratio is 5 : 7.

The age difference in ratio units is 7 - 5 = 2. The difference in years is 6, so each ratio unit must be 6/2 = 3 years. Multiplying the ratio numbers by 3, we get the actual ages as ...

  5 : 7 = (3·5) : (3·7) = 15 : 21

Answer:

-5

Step-by-step explanation

Given the function  f(x)=-4x^2+2x-5, the y intercept occurs at x = 0

Substitute x = 0 into the function and find y as shown;

f(x)=-4x^2+2x-5

f(0)=-(0)^2+2(0)-5

f(0)=0-5

f(0) = -5

The coordinate point is (0, -5)

Hence the value of the y coordinated is -5
