which two number does the square root of 61 lie between on a number line?

Answer:

Step-by-step explanation:

(a - b)² + 4ab = a² + b² - 2ab + 4ab

Combine like terms

                    = a² + b² + 2ab

                    = (a +b)²

                    = (a +b)(a + b)

Answer:

6

Step-by-step explanation:

1/2 of 12 is 6

Zeke ate twice as much as Niko, so he ate 12 and Niko ate 6.

This makes 18 cookies eaten in total.

Answer:

1.2 feet

Step-by-step explanation:

30 feet* 1/25 = 6/5 feet = 1.2 feet

Step-by-step explanation:

correct answer is 168.

hope this helps you.

Hey there!

56 × 3

= 56 + 56 + 56

= 112 + 56

= 168

Basically you had to multiply 6(3), which gave you 18, right? Okay, so you BRING DOWN your 8 and CARRY the 1 OVER your 5. Then you MULTIPLY 5(3), which is 15, right? Then you ADD 15 + 1, which is 16,right?

Thus, that’s why: [168] is most likely your result. (Look at the picture below for better steps )

Good luck on your assignment & enjoy your day!

Answer:

a)  (6, 6)  and  (7, 4)

b)  [tex]t(n)=-2n+18[/tex]

c)  see attached

Step-by-step explanation:

From inspection of the table, we can see that as n increases by 2, t(n) decreases by 4.  Therefore, as this a directly proportional relationship, it is a linear function.

So as n increases by 1, t(n) will decrease by 2.

Therefore, the remaining two ordered pairs are:

(6, 6)

(7, 4)

We know that the function decreases by 2 each time n increases by 1, so the slope (gradient) of the linear function will be -2.

Using the point-slope formula:  [tex]y-y_1=m(x-x_1)[/tex]

(where [tex]m[/tex] is the slope and [tex](x_1,y_1)[/tex] is a point on the line)

Given:

[tex]\implies y-16=-2(x-1)[/tex]

[tex]\implies y=-2x+18[/tex]

[tex]\implies t(n)=-2n+18[/tex]

Graphing

To find the y-intercept, substitute [tex]n=0[/tex] into the equation:

[tex]\implies t(0)=-2(0)+18=18[/tex]

Therefore, the y-intercept is (0, 18)

To find where the line crosses the x-axis, set the equation to zero and solve for n:

[tex]\implies -2n+18=0[/tex]

[tex]\implies 2n=18[/tex]

[tex]\implies n=9[/tex]

Therefore, the line crosses the x-axis at (9, 0)

Step-by-step explanation:

a) The area of Australian desert is 3,830,040km²

b)The approximate number of dingos will be  517,055

a) Given the following parameters;

Area of Sahara desert = 9,000,000km²

If the Australian desert is 42.556% of the size of the Sahara desert in Africa, then the area of the Australian desert is expressed as:

Area of Australian desert = 0.42556 * 9,000,000

Area of Australian desert = 3,830,040km²

b) If dingo density is approximately 0.135 animals km² during the dry season, the approximate number of dingos in the Australian desert during this season. will be:

number of dingos =  0.135 * 3,830,040km²

number of dingos = 517,055.4

Hence the approximate number of dingos will be  517,055

Step-by-step explanation:

Hi!

In any quadratic in the form you have given ([tex]ax^2+bx+c=0[/tex]), the discriminant is ALWAYS

[tex]b^2-4ac[/tex]

Given the quadratic formula:

[tex]x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}[/tex]

-------------------------------------------------------------------------------------------------------------

The discriminant would be the part of the equation that is under the square root.

-------------------------------------------------------------------------------------------------------------

Therefore, your answer is [tex]b^2-4ac[/tex]

Answer:

180 sq cm

Step-by-step explanation:

Square 1 formed on hypotenuse of the triangle, squares 2 and 3 are formed on the perpendicular legs of the triangle. Thus, by Pythagoras Theorem, A(square 1) will be equal to the sum of the areas of (square 2) and (square 3).

[tex]\implies A(square \:1) =A(square \:2)+A(square \:3) \\ \\ \implies \: A(square \:1) =100 + 80\\ \\ \implies \: A(square \:1) =180 \: {cm}^{2} [/tex]
