The product of five and a number plus 10 is at least thirty.

Answer:

AB = 1.4 or 7/5

Step-by-step explanation:

(Excuse my rambling but I wanted to be sure of myself)

AD = 2(5/2) = 5

AD is a diameter.

any triangle in a circle with the hypotenuse as the diameter is a right triangle.

Draw a line from point A to point C.

ΔACD is a right triangle.

Solve for ∠CAD:

sin CAD = 3/5 = 0.6000

∠CAD = 36.87°

arc CD = 2 x 36.87°  = 73.74°

arc BC = arc CD = 73.74°

arc DB = 147.48°

∠BAD = 1/2 (147.48°) = 73.74°

draw a line from point D to point B

ΔBAD is a right triangle.

cos 73.74° = AB/5

AB = 1.4

Answer:

Presumably this is a multiple choice question, and without seeing the potential answers, we can't tell you which ones are correct.

A few things can however be said about this function:

1) It describes a parabola that extends upward infinitely.  We can see this because it's in the classic format ax² + bx + c, and all terms are positive.

2) We can find the x-intercepts by solving for zero.  In this case we can do that by factoring it:

x² + 9x + 18 = 0

x² + 3x + 6x + 18 = 0

x(x + 3) + 6(x + 3) = 0

(x + 6)(x + 3) = 0

So the x intercepts occur at (-6, 0) and (-3, 0)

3) we can find its vertex by taking its derivative and solving for zero:

f'(x) = 2x + 9

0 = 2x + 9

x = -4.5

We can then plug that coordinate into the original function to find the y coordinate:

f(x) = x² + 9x + 18

f(-4.5) = 20.25 - 40.5 + 18

= -2.25

So the vertex is at (-4.5, -2.25)

4) As mentioned, the derivative of f(x) is f'(x) = 2x + 9.  The integral is:

x³ / 3 + 9x² / 2 + 18x + C

Step-by-step explanation:

Given

[tex]\frac{3}{5}a + 10[/tex]

Required

Select 3 equivalent expressions

[tex]\frac{3}{5}a + 10[/tex]

Express 3 as 2 + 1

[tex]\frac{2 + 1}{5}a + 10[/tex]

Rewrite as:

[tex]\frac{2a + a}{5} + 10[/tex]

Split

[tex]\frac{2a}{5} + \frac{a}{5} + 10[/tex] ----- Option (A)

[tex]\frac{3}{5}a + 10[/tex]

Express 10 as 14 - 4

[tex]\frac{3}{5}a + 14 - 4[/tex]

Rewrite as:

[tex]14+\frac{3}{5}a - 4[/tex] --- Option (C)

[tex]\frac{3}{5}a + 10[/tex]

Factor out 1/5

[tex]\frac{1}{5}(3a + 50)[/tex] --- Option D

Answer:

Option D

Answer:

Option D

Step-by-step explanation:

Measure of adjacent side = 20

Measure of Hypotenuse = 24

Since, measures of adjacent side and Hypotenuse have been given in the question, cosine ratio will be applied to find the measure of angle x.

cos(x) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

cos(x) = [tex]\frac{20}{24}[/tex]

x = [tex]\text{cos}^{-1}(0.833)[/tex]

  = 33.55°

  ≈ 33.6°

Option D is the answer.

Answer: 7

Step-by-step explanation: So 24:28 is equal to 6:? so if we divide 24 by 6 we get 4. So 28 divided by 4 is 7. 6:7 is equal to 24:28.

Answer:

The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count

Step-by-step explanation:

Solve with yourself

answer is 4√2

because, using pythagoras theorem

x² = 4² + 4²

x² = 16 + 16

x² = 32

x = √32

x = √(16 × 2)

x = √16 × √2

x = 4 × √2

x = 4√2
