Answer:

1) [tex]-10x^2[/tex]

2) [tex]64x^2[/tex]

Step-by-step explanation:

First question:

-2x . 5x = [tex]-10x^2[/tex]

Second question:

[tex](8x)^2=8x.8x= 64x^2[/tex]

Answer:

a. V = 3M

b. T = 5S

c. Y = 17x

d. H = 12M

e. P = 0.5N

Step-by-step explanation:

a. V= 12 when M =4

12/4 = 3, so in this case, V is 3 times M, that is, V = 3M

b. T= 5 when S=1

5/1 = 5, so in this case, T is 5 times S, that is, T = 5S

c. Y= 34 when x=2

34/2 = 17, so in this case, Y is 17 times x, that is, Y = 17x

d. H=48 when M=4

48/4 = 12, so in this case, H is 12 times M, that is, H = 12M

e. P= 5 when N=10

5/10 = 1/2 = 0.5, so in this case, P is half of N, that is, P = 0.5N

Answer:

5

Step-by-step explanation:

5+12= 17

Equation/Question:

P+12=17 What does P equal in this situation?

Answer/Steps to answer:

1. Subtract 12 from both sides.

p=17-12

2. Simplify  17-12 to  5.

p=5

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

Checking:

P+12=17

1. Let p=5.

5+12=17

2. Simplify  5+12 to 17.

17=17

Answer:  

Use continuity to evaluate the limit.

lim 16+radical x/ radical 16+x

1+9

Consider the intervals for which the numerator and the denominator are continuous.

The numerator 16+ radical x is contintuous on the interval

[0,00)

0

The denominator V16 + I is continuous and nonzero on the interval

(16,00)

X

The interval for which the quotient is continuous is the intersection of the above intervals.

16+

Therefore, the quotient

is continuous on the interval

716 +1

[-16,0]

X

Since 2

9 is in the interval (0, 0), then fis continuous at x = 9. Therefore,

Step-by-step explanation:

Given:

The scale on a map is 1:25000.

To find:

How many km on the ground is represented by 6cm on the map?

Solution:

Let x be the km on the ground.

We know that,

1 km = 1000 m

1 m = 100 cm

So,

1 km = 100,000 cm

x km = 100,000x cm

The scale on a map is 1:25000. It means the ratio of map and ground is equal to 1:25000.

[tex]\dfrac{1}{25000}=\dfrac{6}{100,000x}[/tex]

[tex]\dfrac{100,000x}{25000}=6[/tex]

[tex]4x=6[/tex]

[tex]x=\dfrac{6}{4}[/tex]

[tex]x=1.5[/tex]

Therefore, 1.5 km on the ground is represented by 6cm on the map.

Answer:

(1/2)x+(1/4)=x

x=0.5

3x+3=2(x+7)

x=11

2(x-5)+7=x+8

x=11

0.8x+5=0.2(40-x)

x=3

5(x-1)-6x=-11x

x=0.5

6(x+2)-x=4(x+4)+7

x=11

(1/2)(x+8)+(3/2)x=10

x=3

Step-by-step explanation:

(1/2)x+(1/4)=x

x-0.5x=0.25

0.5x=0.25

x=0.5

3x+3=2(x+7)

3x+3=2x+14

3x-2x=14-3

x=11

2(x-5)+7=x+8

2x-10+7=x+8

2x-x=8+10-7

x=11

0.8x+5=0.2(40-x)

0.8x+5=8-0.2x

0.8x+0.2x=8-5

x=3

5(x-1)-6x=-11x

5x-5-6x=-11x

11x-x=5

10x=5

x=0.5

6(x+2)-x=4(x+4)+7

6x+12-x=4x+16+7

6x-4x-x=16+7-12

x=11

(1/2)(x+8)+(3/2)x=10

Well on my end i got 47.12, with pi included

Step-by-step explanation:

The surface area of the cylinder with the diameter 2cm and height 15cm  is [tex]100.48 \; cm^2[/tex]

Calculation to find Surface area of cylinder:

Given the diameter of the cylinder is 2cm and height  15cm

Formula :

The surface area of the cylinder =[tex]2\pi r^2+2\pi rh[/tex]

where 'r' is the radius and 'h' is the height of the cylinder

Diameter = 2cm

[tex]radius =\frac{diameter }{2} =\frac{2}{2} =1[/tex]

radius = 1cm and height is 15 cm

the value of pi is 3.14

Substiute all the values

[tex]SA = 2\pi r^2+2\pi rh\\SA=2(3.14)(1)^2+2(3.14)(1)(15)\\SA=6.28+94.2\\SA=100.48 cm^2[/tex]

The surface area of the cylinder with the diameter 2cm and height 15cm  is [tex]100.48 \; cm^2[/tex]

The range of the function is the set of all positive real numbers, or y > 0.

The range of a function is the set of all possible values that the function can output.

The function is given in the question as:

y = √(x+7+5)

In the case of the function y = √x + 7 + 5, the range is the set of all possible values of y that can be obtained by substituting different values of x into the function.

To find the range of this function, we need to consider the values of x that can be used in the function. The square root of a number must be non-negative, so x must be greater than or equal to 0.

In other words, the domain of the function is x ≥ 0.

We can now substitute different values of x into the function to find the range.

For example, if x = 0, then y = √0 + 7 + 5 = 7 + 5 = 12. If x = 1, then y = √1 + 7 + 5 = 8 + 5 = 13. And so on.

We can see that as we increase the value of x, the value of y also increases. This means that the range of the function is the set of all positive real numbers, or y > 0.

Therefore, the range of y = √x + 7 + 5 is y > 0.

Answer:  b - edge

Step-by-step explanation:

Answer:

x = 1

y = -2

Step-by-step explanation:

5x - 2y = 9 -----------(I)

2x + 7y = -12 --------------(II)

Multiply (I) by 7          35x - 14y = 63

Multiply (II) by 2         4x + 14y  = - 24   {Now add and thus y will be eliminated}

                                  39x         =      39

                                          x = 39/39

x = 1

Plugin x = 1 in equation(I)

5*1 - 2y = 9

5 -2y = 9

    -2y = 9 -5

    -2y = 4

        y = 4/-2

        y = -2
