7+(2+6) to the 2nd power * 4(1/2) to the 4th power

Answer:

1715= 1/3 x 3.14 x r x r x 63

= 65.94 x r^2

÷65.94

26.01 = r^2

Square root

Radius is 5.1

1080 = 1/3 x 3.14 x 5.1^2 x h

1080 = 27.22 x h

÷27.22

39.67 = h

(Haven't been actually rounding up in my calculation, when I divided.)

Check:

1/3 x 5.1^2 x 39.67 x 3.14 = 1079.968146.

So, height is about 39.67cm

Hope this helps!

Answer:

1/2(8*8)5

1/2* 320

ans= 160

is this answer is right??

Step-by-step explanation:

soln;

b1 = 5m

b2 = 8m

h = 8m

now,

a = 1/2(b1+b2)h

  = 1/2(5+8)8

  = 52 cm^2

Answer:

length and width of the photo are: w = 6cm l = 8cm

Step-by-step explanation:

Area = 168cm^2

Area = w • l

168 = (x + 3 + 3) • (x + 2 + 3 + 3)

168 = (x + 6) • (x + 8)

expand

168 = x^2 + 14x + 48

subtract 168 from both sides

0 = x^2 + 14x - 120

simplify

0 = (x - 6) • (x + 20)

x = 6 or -20

since we are dealing with a measurement of a physical object x > 0

x = 6cm

w = x = 6cm

l = x+2 = 8cm

Answer:

the actual profit after working expenses not included in the calculation of gross profit have been paid.

Step-by-step explanation:

To calculate the net profit figure, subtract the total expenses from the total revenue, as seen in the following equation: Net profit = Total Revenue - Total Expenses. In this equation, revenue represents the total amount of money earned from product sales in addition to income from other places, including investments.

Answer: B, D

Step-by-step explanation:

A parallelogram is a quadrilateral with 2 pairs of parallel sides, so if there are no parallel sides, it can't be a paralellogram.

D is true by the definition of a parallelogram.

Step-by-step explanation:

A is excluded because in the second() x² should be negative

B is excluded because if you solve it -(-x² give you + x²

C is excluded because in the second() 2x and 1 should be negative

so D is right

Step-by-step explanation:

1.12 times 25 is 28

1.28 times 3000

To find a line perpendicular to the original line, we must set the new slope as the negative reciprocal of the original slope, 2/5.

So the slope of the perpendicular line is -5/2

Now using the point slope form, we have the slope -5/2  and (3,6)

    [tex]y- 6 = \frac{-5}{2}(x-3)\\y-6 =\frac{-5}{2} x + \frac{15}{2} \\y = \frac{-5}{2} x + \frac{15}{2} + 6\\y= \frac{-5}{2} x + \frac{15}{2} + \frac{12}{2} \\y = \frac{-5}{2}x +\frac{27}{2}[/tex]

Hope that helps!

Hello.

We have a point that the line passes through:

[tex]\mathrm{(-5,-1)}[/tex]

We also have the line's slope:

[tex]\mathrm{4}[/tex]

Right now, we do not have enough information to write the equation of the line in slope-intercept form. We need to know the slope and the y-intercept. We do know the slope, but we do not know the y-intercept...yet.

We do have enough information to write the line's equation in Point-Slope Form:

[tex]\mathrm{y-y1=m(x-x1)}[/tex]

Plug in the values:

[tex]\mathrm{y-(-1)=4(x-(-5)}[/tex]

[tex]\mathrm{y+1=4(x+5)}[/tex]

Use the Distributive Property (a(b+c)=ab+ac) :

[tex]\mathrm{y+1=4x+20}[/tex]

Move 1 to the right:

[tex]\mathrm{y=4x+20-1}[/tex]

Subtract:

[tex]\mathrm{y=4x+19}[/tex]

Now we have the equation in slope-intercept form.

Therefore, the answer is

[tex]\mathrm{y=4x+19}[/tex]

I hope it helps.

Have a nice day.

Step-by-step explanation:

Plug the information into the Slope-Intercept Formula like so:

Answer:

(-2,11) (0,3) (2,-5) (4,-13)

Step-by-step explanation:

used desmos calculator

Answer:

  (a) 10

  (b) -3 3/4

  (c) -4/3

Step-by-step explanation:

Function values can be found by direct substitution of the argument into the function expression. Inverse function values can be found by solving the function equation for the variable value.

f(-2)= 3(-2)² -2 = 12 -2

f(-2) = 10

__

g^-1(-3/4)

-3/4 = x +3

-3 3/4 = x . . . . . . subtract 3

__

Substitute the expressions as required and solve for x.

  f(g(x)) = g(f(x))

  f(x+3) = g(3x² -2)

  3(x +3)² -2 = (3x² -2) +3

  3(x²2 +6x +9) -2 = 3x² +1

  3x² +18x +25 = 3x² +1

  18x = -24

  x = -24/18 = -4/3

_____

Additional comment

When solving an equation graphically, we like to write it in the form h(x) = 0 when possible. The graphing calculator easily identifies x-intercepts. This form makes each solution an x-intercept.

  f(g(x)) = g(f(x))   ⇔   f(g(x)) -g(f(x)) = 0

__

The value of the inverse function can be found similarly. We want to find x such that g(x) = -3/4, so we can look for the solution to g(x) +3/4 = 0.

Answer:

y = -3x² - 3x + 6

Step-by-step explanation:

main formula: r×(x² - (a + b)x + ab) = y

r×(x² - (-2 + 1)x -2×1) =y

r×(x² +x -2) = y

by using the point (0,6) →

r×(0² + 0 -2) = 6

r×-2 = 6

r= -3

so

y= -3x² -3x +6
