No, the top one would be 33. You're adding the brick next to another brick together for example; 3 and 4 are together; makes 7. 4 and 5 are together makes 9. 5 and 3 are together makes 8.

2. That's unit rate; You have to divide 225 by 15 which gives you 15. 15 x 15 = 225 so, 15 x ( 1 hour ) = 15 hours.

6. Y = 34. 98 + 4 = 102. 102 divided by 3 = 34. 102 - 4 = 98.

That's all I can do sorry

Find the absolute maximum and minimum of the function on the given domain. f (x comma y )equals 8 x squared plus 7 y squared on

pickupchik [31]

Answer:

the maximum value is 7

The minimum value is 0

Step-by-step explanation:

Step One : Interpret the question

The above question can be written like

The Equation

$f(x,y) = 8x^2 +7y^2$

The diagram of the triangular plate and the bounded lines is shown on the first uploaded image

From the diagram $f(0,0) = 8(0)^2 +7(0)^2 =0$

$f(1,0) =8(1)^2 + 7(0)^2 = 8$

$f(0,1) =8(0)^2 + 7(1)^2 = 7$

Partial differentiation of the equation w.r.x

$A =\frac{\delta f}{\delta x } = 16x$

Partial differentiation of the equation w.r.y

$B =\frac{\delta f}{\delta y } = 14y$

Looking at the diagram the maximum value is 7 i.e at (x , y) = (0,1)

The minimum value is 0 i.e (x , y) = (0,0)

Is the square root of 15 greater than, less then , or equal to 4?

Sever21 [200]

Answer:

less than 4

Step-by-step explanation:

the closest perfect square root to 15 is the square root of 16, which produces the number 4. since 16 is greater than 15, the value of the square root of 15 is less than 4.

hope this helps!

Find the equation of the circle in standard form for the given center (h, k) and radius r: (h, k) = (5, 4), r = 2

kenny6666 [7]

If cente ris (h,k) and radius is r then
equatn is (x-h)^2+(y-k)^2=r^2

so

center (5,4)
r=2
h=5
k=4

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

first option

Pleaseeeeee helppppppppppp

Ok so we have the first portion. We need to do cross multiplication first. So that would be 20(2x - 9) and 10(9)

So
20(2x - 9)=90
40x - 180=90
Then add 180 to itself then to 90
40x=270
X=6.75

Now let’s set the next one up knowing what we know from the previous one.

18(3x + 4)= 12(15)
54x + 72=180
Subtract 72 from it’s self and 180
54x=108
X=2
