What does 70.2 rounded to the nearest ten?

Answer:

Since r is the distance from the origin to (x,y), it is the magnitude r=√x2+y2. Alternatively, from the equation (1), one can calculate directly that x2+y2=r2cos2θ+r2sin2θ=r2(cos2θ+sin2θ)=r2.

Step-by-step explanation:

Answer: P= -60

Step-by-step explanation:

5/6p +1=3/4p -4

5/6p=3/4p-4.       Subtract 1 from both sides

5p=9/2p-30.        Trick( if there is a fraction multiply the denominator on both sides to make it a non fraction so life is easier, as I did I first multiply by 6)

10p=9p-60.           multiply the second denominator on both sides(multiple by 2)

P=-60.                     Subtract 9p on both sides and keep the sign and you’ll get -60

Answer: The answer is m= ≥4.50

The required inequality is m ≥ 4.50

A relationship between two expressions or values that are not equal to each other is called inequality.

Given that, A shirt that you want to buy costs $15.50. You can use a $5 discount coupon if you spend at least $20.

Cost of the shirt = $15.50

you can use a $5 discount coupon if you spend at least $20

The question requires you to find how much more you need to spend to be able to use the $5 discount coupon

The shirt already cost $15.50

Total amount you need to spend = $20

Let the amount remaining = m

m ≥ $20 - 15.50

m ≥ $4.50

Hence, you need to spend $4.50 in order to be able to use the $5 discount coupon.

Answer:

m=7

Step-by-step explanation:

step 1: -3m+6m-12=9

step 2: 3m-12=9

step 3: 3m=21

step 4: m=7

Answer:

m=7

Step-by-step explanation:

1. Simpilfy both sides of the equation & combine like terms

2.  Add 12 to both sides

3. Divide 3 from both sides

21 divided by 3 equals 7.

The above expression is not in its simplest form, and we need to simplify it, that is what asked in the question.

Given equation,

[tex](9 {x}^{2} - 3x + 7) + ( - 3 {x}^{2} + 2)[/tex]

First of all, let's open the parentheses to combine the like terms for simplifying.

[tex]9 {x}^{2} - 3x + 7 - 3 {x}^{2} + 2[/tex]

Arranging the like terms, x² with x², x with x and constant terms near to each other.

[tex]9 {x}^{2} - 3 {x}^{2} - 3x + 7 + 2[/tex]

Simplying further,

[tex](9 - 3) {x}^{2} - 3x + 9[/tex]

[tex]6 {x}^{2} - 3x + 9[/tex]

So, the correct option is C

Answer:

x=35

Step-by-step explanation:

Triangles always add up to 180 degrees, and so do straight lines. so 180-131=49, 49+96=145, 180-145=x, so x=35 degrees

Step-by-step explanation:

Answer:

C. 17

Step-by-step explanation:

I'm assuming you need the hypotenuse so to get that you do

The square root of a^2 + b^2

                            a squared + b squared

So it becomes square root of 8^2 + 15^2

                    =   square root of 64 + 225

                    =   square root of 289

                    =   17

Answer:

no To multiply three factors, we first multiply two of the factors together. Then we multiply the product we get by the third factor. Since multiplication is commutative, we may multiply numbers in any order.

Answer:

5:2

Step-by-step explanation:

In centimetres

convert 2 m to cm which will be 200 cm

then simplify 200 cm:80 cm --> 5:2

(we cancelled out the zero --> 20:8 then divide 20/2= 10 and 8/2= 4

again the same --> 10/2= 5 and 4/2= 2.

5 and 2 are prime numbers which have no other factor except for 1 and themselves so it cannot be simplified further.

Therefore your answer is 5:2

In metres

convert 80 cm to m which will be 0.8 m

the same steps: simplify 2:0.8

to remove the decimal move the decimal place one to the right --> 8

so you also have to move the decimal place to the right for the numerator: 20

20/8 = 5/2

Answer:

[tex]x=\pm 3\text{ or } x=\pm 2i[/tex]

Step-by-step explanation:

So we have the equation:

[tex]x^4-5x^2-36=0[/tex]

Let's let u equal x² so:

[tex]u^2-5u-36=0[/tex]

Factor. We can use -9 and 4. So:

[tex]u^2+4u-9u-36=0[/tex]

From the first two terms, factor out a u.

From the last two terms, factor out a -9. So:

[tex]u(u+4)-9(u+4)=0[/tex]

Grouping:

[tex](u-9)(u+4)=0[/tex]

Zero Product Property:

[tex]u-9=0 \text{ or } u+4=0[/tex]

On the left, add 9. On the right, subtract 4:

[tex]u=9\text{ or } u=-4[/tex]

Substitute back u:

[tex]x^2=9\text{ or } x^2=-4[/tex]

Take the square root:

[tex]x=\pm 3\text{ or } x=\pm 2i[/tex]

And we're done!

Answer:

TV or VT

Step-by-step explanation:

A line is defined by the two points lying on an infinitely long straight paths.

From the picture attached,

There are two endless paths 'l' and 'm' which contain (R, U) and (V, T), intersecting at a point S.

Therefore, line 'm' will be represented by VT or TV.

And line 'l' will be represented by RU or UR.
