Step-by-step explanation:

area of front face=(12+8)/2 ×8=80 cm²

volume=80×22=1760 cm³

Answer:

+6 and -6.

Step-by-step explanation:

x^2 - 10 = 26​

x^2  = 26  + 10 = 36

x = +/- 6.

The two values which x can have will be +6 and -6

What is Quadratic Equation?

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c =0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

Given data ,

Let the equation be f ( x )

The equation f ( x ) is x² - 10 = 26

Now , adding 10 on both sides , we get

x² = 36

Taking square roots on both sides , we get

x = ±6

We know , (-6)² = 36 and (+6)² = 36

Therefore , x can have 2 solutions , which is ±6

Hence ,  the two values which x can have will be +6 and -6

Answer:

 (c + 2d) • (9d - 2c)

Step-by-step:

Step  1  :

Equation at the end of step  1  :

 ((c + 2d)2) -  (c + 2d) • (3c - 7d)

Step  2  :

Pulling out like terms :

2.1      Pull out     c+2d

After pulling out, we are left with :

     (c+2d) • ( (c+2d) +( (-1)  *  (3c-7d) ))

Answer:

(c+2d)(9d - 2c) = [tex]5dc - 2c^{2} + 18d^{2}[/tex]

Step-by-step explanation:

[tex](c+2d)^{2} - (c+2d)(3c-7d)[/tex]

[tex](c+2d)(c+2d) - (c+2d)(3c-7d)[/tex]

Both sides have (c+2d) so pull out (c+2d)

(c+2d) [(c+2d) - (3c-7d)]

(c+2d) [c+2d - 3c +7d]

(c+2d) [-2c + 9d] = (c+2d)(9d - 2c)

(c+2d)(9d - 2c) = [tex]9dc - 2c^{2} + 18d^{2} -4dc[/tex] = [tex]5dc - 2c^{2} + 18d^{2}[/tex]

Answer:

3.2  (and the equation is 3.4 + x = 6.6)

Step-by-step explanation:

the word problem is written as:

3.4 + x = 6.6

we want to solve for x.

to isolate x by itself, subtract 3.4 from both sides. (3.4 - 3.4=0 & 6.6 - 3.4 = 3.2)

now we have     x = 3.2

so x equals 3.2

Answer:

A. Inside the circle

Step-by-step explanation:

K(0, 0), U (6, - 4), V ([tex] \sqrt 2,\: 7)[/tex]

In order to determine whether point V lie inside, outside or on the circle, first we will find the distances between points K & U and then K & V.

KU would be radius of the circle.

[tex]d(KU) = \sqrt{ {(6 - 0)}^{2} + {( - 4 - 0)}^{2} } \\ = \sqrt{ {6}^{2} + {( - 4)}^{2} } \\ = \sqrt{36 + 16} \\ \red{ \bold{ d(KU)= \sqrt{52} }} \\ \\ d(KV) = \sqrt{ {( \sqrt{2} - 0)}^{2} + {( 7 - 0)}^{2} } \\ = \sqrt{ {( \sqrt{2)} }^{2} + {(7)}^{2} } \\ = \sqrt{2 + 49} \\ \purple{ \bold{ d(KV)= \sqrt{51} }} \\ \\ \because \: d(KU) > d(KV) \\ [/tex]

Hence point V lie inside of the circle.

Answer:

Carmen received $7.14 for each hour she worked.

Step-by-step explanation:

$350 for 49 hours of work

Write an equation, with hours as the variable

$350 = 49h

Divide both sides of the equation by 49 to find the unit rate

h = $7.14

Carmen received $7.14 for each hour she worked.

Answer:

2010 cu ft to the nearest whole number.

Step-by-step explanation:

Volume = π r^2 h

= 3.14 * 4^3 * 10

= 2009.6

The volume of the water tank is approximately 502 cubic feet.

A cylinder is a 3-D figure that has a radius and a height.

The volume of a cylinder is given as πr²h.

Example:

The volume of a cup with a height of 5 cm and a radius of 2 cm is

Volume.

= 3.14 x 2 x 2 x 5

= 62.8 cm³

We have,

The volume V of a cylinder can be calculated using the formula V = πr²h, where r is the radius of the base and h is the height.

Substituting the given values, we get:

V = π (4 ft)² (10 ft)

V = 3.14 (16 ft²) (10 ft)

V = 502.4 ft³

Rounding this answer to the nearest whole number gives a final answer of V = 502 ft^3.

Therefore,

The volume of the water tank is approximately 502 cubic feet.

Answer:

121

Step-by-step explanation:

Given

f(x) = - (x + 8)(x - 14) ← expand factors using FOIL

     = - (x² - 6x - 112) ← distribute by - 1

     = - x² + 6x + 112

Given a quadratic in standard form. y = ax² + bx + c : a ≠ 0

Then the x- coordinate of the vertex is

[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]

f(x) = - x² + 6x + 112 ← is in standard form

with a = - 1 and b = 6, thus

[tex]x_{vertex}[/tex] = - [tex]\frac{6}{-2}[/tex] = 3

Substitute x = 3 into f(x) for corresponding value of y

f(3) = - (3)² + 6(3) + 112 = - 9 + 18 + 112 = 121

vertex = (3, 121 ) ← with y = 121

2/5

Step-by-step explanation:

Answer:

1/6

Step-by-step explanation:

Out of these four card choices, for the first pick there are two even cards and four cards in total. This means that on the first pick there is a 2/4=1/2 chance that you pick an even card. On the second pick, if you do not replace the card, then there is 1 even card remaining, and 3 cards in total, leaving a probability of 1/3. Multiplying these two probabilities together, you get an overall chance of 1/6. Hope this helps!

Answer: x = 12 degrees.

Step-by-step explanation:

The triangle ABC is a right triangle, which means that it has a right angle of 90 degrees.

This is represented by the small square on the bottom-left corner of the triangle.

The angle DBC is 78 degrees. There is also the angle of ABD, which is represented by X.

The right angle is equivalent to 78 degrees and x. You can represent this in an equation, where the sum of 78 degrees and x = 90 degrees, the right angle:

78 + x = 90

x = 12
