3(4p – 5.5) + 11.1 = 8.1 + 3p

Answer:

Part A

71°

Part B

The ladder is been used safely

Step-by-step explanation:

Part A

We solve the above question using Trigonometric function of Cosine

cos x = Adjacent/Hypotenuse

Adjacent = The distance between the house and the bottom of the ladder = 4 feet

Hypotenuse = Length of the ladder = 12 feet

x = Angle

Hence:

cos x = 4/12

cos x = 1/3

x = arc cos (1/3)

x = 70.528779366°

Approximately to the nearest degree

= 71°

Part B

According to the manufacturer, if the angle the ladder forms with the ground, x, is between 70° and 75°, then it meets safety standards. Is this ladder being used safely?

Angle x = 71°

Therefore, the ladder is been used safely

Answer:

3 tiles will not fit together.

Step-by-step explanation:

Measure of an Interior angle of a polygon = [tex]\frac{(n-2)\times 180}{n}[/tex]

Here, n = number of sides of the polygon

Therefore, measure of the interior angles of a regular hexagon,

A = [tex]\frac{(6-2)\times 180}{6}[/tex]

A = 120°

Similarly, interior angle of the regular pentagon,

B = [tex]\frac{(5-2)\times 180}{5}[/tex]

B = 108°

Now m∠A + m∠B + m∠C = 360°

m∠C = 360° - (120° + 108°)

        = 132°

To fit the given three tiles perfectly, interior angle (∠D) of the third Octagonal tile should be 132°.

D = [tex]\frac{(8-2)\times 180}{8}[/tex]

D = 135°

m∠C ≠ m∠D

Therefore, 3 tiles will not fit together.

Answer:

by 12 months both prices will be 180.

Step-by-step explanation:

If you take 12 and multiply it by 10 because that is the monthly subscription, you will get 120 + 60 for the game which equals 180. But if you take 12 and multiply it by 15 you will also get 180.

Hope this helps

Correct option is C.

Answer:

Correct answer is

option c

The polynomial is given as f(x) = (x - 5)(x + 1)(4x + 1).  

        f(x) = x² − 4x + 7.

Given is a polynomial with zeroes -

x = 5, x = - 1 and x = - 1/4

The given zeroes are -

      (x - 5) = 0

       (x + 1) = 0

       4x = - 1

       (4x + 1) = 0

So, we can write the polynomial as -

f(x) = (x - 5)(x + 1)(4x + 1)  

Therefore, the polynomial is given as f(x) = (x - 5)(x + 1)(4x + 1).

Answer:

go search m  a t h w a y it will give you the answer and how did they get the answer

Step-by-step explanation:

Answer:

y = -10/3x - 5

Step-by-step explanation:

slope intercept form:

y = mx + b

10x - 3y = -15

subtract 10x from both sides of the equation

10x - 10x - 3y = -15 - 10x

3y = -15 - 10x

3y = -10x - 15

divide the equation by 3

3y/3 = -10x/3 - 15/3

y = - 10x/3 - 5

Answer:

[tex]\boxed{\textsf{ The value of the polynomial at p = (-2) is \textbf{ -37}.}}[/tex]

Step-by-step explanation:

A polynomial is given to us and we need to find its value at p = (-2) . The given polynomial is :-

[tex]\sf\implies p(x)= 3x^3 -x^2 +2x-5[/tex]

Also second part of the question says what does this tell about the factors of p(x) .

On putting p = (-2) :-

[tex]\sf \implies p(x)= 3x^3 -x^2 +2x-5 \\\\\sf\implies p(-2) = 3 (-2)^3-(-2)^2+2(-2)-5 \\\\\sf\implies p(-2)= 3\times (-8) -4 -4 -5 \\\\\sf\implies p(-2)=-24-4-4-5 \\\\\implies \boxed{ \pink{\sf p(-2)= (-37) }}[/tex]

Now this tells us that ( x + 2 ) is not a factor of the given polynomial. When we divide the given polynomial by (x + 2) then the remainder will be -37 .

Answer:

$288

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 18%/100 = 0.18 per year,

then, solving our equation

I = 3200 × 0.18 × 0.5 = 288

I = $ 288.00

The simple interest accumulated

on a principal of $ 3,200.00

at a rate of 18% per year

for 0.5 years is $ 288.00.

Answer:

C

Step-by-step explanation:

We have: (I rewrote the function)

[tex]f(z_n)={z_{n-1}} ^2+c[/tex]

Given that:

[tex]\displaystyle c=2-3i \text{ and } z_0 = 1 + 2 i[/tex]

The first iterate will be:

[tex]\displaystyle \begin{aligned} f(z_1)&=(z_0)^2+c \\ &=(1+2i)^2+(2-3i) \\ &= (1+4i+4i^2)+(2-3i) \\ &=1+4i-4+2-3i \\ &=-1+i \end{aligned}[/tex]

The second iterate will be:

[tex]\begin{aligned}f(z_2) &=(z_1)^2+c\\ &=(-1+i)^2+(2-3i) \\&= (1-2i+i^2)+(2-3i) \\&=1-2i-1+2-3i \\&=2-5i \end{aligned}[/tex]

And the third iterate will be:

[tex]\begin{aligned} f(z_3)&=(z_2)^2+c\\ &=(2-5i)^2+(2-3i) \\ &=(4-20i+25i^2)+(2-3i) \\ &=4-20i-25+2-3i \\ &=-19-23i \end{aligned}[/tex]

Hence, our answer is C.

Answer:

To write 14.7 as a fraction you have to write 14.7 as the numerator and put 1 as the denominator. Now you multiply the numerator and denominator by 10 as long as you get in the numerator the whole number.

14.7 = 14.7/1 = 147/10

And finally, we have:

14.7 as a fraction equals 147/10
