Find the surface area of the above solid

Answer:

12

Step-by-step explanation:

Answer:

A) 33+3i

Step-by-step explanation:

Use the FOIL method: (a+b)(c+d)=ac+ad+bc+bd(a+b)(c+d)=ac+ad+bc+bd.

15−15i+18i+18

combine like terms

(15+18)+(−15i+18i)

simplify

33+3i

Answer:

[tex] 88 \: {in}^{2} [/tex]

Step-by-step explanation:

Area of the figure = Area of rectangle with dimensions 16 in and 4 in + Area of two right triangles with base (7 - 4 = 3) 3 in and height 8 in

[tex] = 16 \times 4 + 2 \times \frac{1}{2} \times 3 \times 8 \\ \\ = 64 + 24 \\ \\ = 88 \: {in}^{2} [/tex]

Answer:

-9; 1

Step-by-step explanation:

x+4=5

x=5-4

x=1

x+4=-5

x=-5-4

x=-9

The solution of the quadratic equation (x + 4)^2 = 25 is x = -9 and x = 1

The correct answer is option (C)

"It is a polynomial with degree 2. The general form of quadratic equation is ax²+ b x + c =0, where a, b, c are real numbers with a ≠ 0."

For given example,

We need to find the solution of the quadratic equation (x + 4)^2 = 25.

⇒ (x + 4)^2 = 25

⇒ x² + 2(4)(x) + (4)² = 25

⇒ x² + 8x + 16 = 25

⇒ x² + 8x - 9 = 0

⇒ x² + 9x - x - 9 = 0

⇒ x(x + 9) - 1(x + 9) = 0

⇒ (x + 9)(x - 1) = 0

⇒ x + 9 = 0   and x - 1 = 0

⇒ x = -9 and x = 1

The correct answer is option (C)

Answer:

5 ≤ h < 10        = 2

15 ≤ h < 20    = 10

20 ≤ h < 25    = 2

Answer:

50°

Step-by-step explanation:

Let :

Let the angle = x

Second angle = x + 10

Third angle = x - 10

Sum of angles in a triangle = 180

x + (x + 10) + (x - 10) = 180

x + x + 10 + x - 10 = 180

3x = 180

x = 180 / 3

x = 60

Smallest angle :

x - 10 = 60 - 10 = 50°

Answer:

3x - (15 x 3) = 90

or

3x - 45 = 90

Explanation:

there are 3 boxes. We don't know how many are in them yet, so we write this as 3x. However, we know that we give away 15 to 3 different teachers. 15 x 3 = 45

Therefore the first part is 3x - 45

We also know that in the end we have 90 left.

So our final equation is:

3x - 45 = 90

Answer:

D

Step-by-step explanation:

The maximum value is the y- coordinate of the vertex

Given a quadratic in standard form , y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

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

y = - x² + 6x + 5 ← is in standard form

with a = - 1 and b = 6 , then x- coordinate of vertex is

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

Substitute x = 3 into the function for y- coordinate of vertex

y = - 3² + 6(3) + 5 = - 9 + 18 + 5 = 14

maximum value is 14 → D

Answer:

1. 6.13

2. 0.57

Step-by-step explanation:

1. 7 x 4 = 28

28 / 8 = 3.5

3.5 x 7 = 24.5 / 4 = 6.13

s = 6.13

2. 2 x 3 = 6

6 / 7 = 0.85

0.85 x 2 = 1.71

1.71 / 3 = 0.57

s = 0.57

[tex]4)\ C[/tex]

Step-by-step explanation:

1)

Let's use the Pythagorean Theorem:

[tex]X^2 + 13^2 = 21^2[/tex]

[tex]X^2 + 169 = 441[/tex]

[tex]X^2 = 272[/tex]

[tex]X= \sqrt{272} = 4\sqrt{17} = 16.5[/tex]

2)

Let's use the Pythagorean Theorem:

[tex]16^2 + 28^2 = x^2[/tex]

[tex]x^2 = 1040[/tex]

[tex]x = \sqrt{1040} = 4\sqrt{65} = 32.2[/tex]

3)

Let's use the Pythagorean Theorem:

[tex]7^2 + 24^2 = 25^2[/tex]

As this equation is correct, these three lengths could be used in a right triangle.

Let's use the Pythagorean Theorem:

Answer:

CD  ║ EF and ED is transversal, hence

We can see that:

Since the angles CDB and ADB sum to 180, these are consecutive interior angles, therefore AB and CD are parallel lines.

PU and QT are parallel and PT is transversal, therefore:

Now find the missing angles of ΔQTP

Now, we see that:

As  ∠TPQ ≅ ∠SQR  these angles are corresponding angles.

Therefore PT and SQ are parallel lines.
