equivalent to: 2(4x+5y)

Answer:

2(4x+5y)

Step-by-step explanation:

the sum of 8x+10y is 8x+10y

i guess you could make it even more complicated if you want

ln(8x)=ln(1/(10y))

ln(8x/(1/(10y)))

or you can just keep it simple

8x+10y = 2(4x+5y)

Answer:

-31

Step-by-step explanation:

We are given with a function f(x) = - 4x - 11 , and we need to find f(5) . For which , we just have to put x = 5 in f(x) . So , by putting x = 5 , we have

[tex]{:\implies \quad \sf f(5)=-(4\times 5)-11}[/tex]

[tex]{:\implies \quad \sf f(5)=-20-11}[/tex]

900/250 is 3.6

3.6 * 5 = 18

Answer:

18 minutes

Step-by-step explanation:

Hi! Okay, let's get started!

Let's find her rate per minute first = 250/50 = 50 words per minute

Now, we need to find the time for 900 words, so we do 900/50, which gives you 18, or 18 minutes!

Step-by-step explanation:

The limit exists because it's continuous since they equal each other

when x approaches zero.

Substitute both expressions with x=0 and both of them will equal 2, so the limit should be 2.

Answer:

See Below.

Step-by-step explanation:

We want to prove the trigonometric identity:

[tex]\displaystyle \frac{\sec^2(\theta)-1}{\sin(\theta)}=\frac{\sin(\theta)}{1-\sin^2(\theta)}[/tex]

To start, let's simplify the right side. Recall the Pythagorean Identity:

[tex]\sin^2(\theta)+\cos^2(\theta)=1[/tex]

Therefore:

[tex]\cos^2(\theta)=1-\sin^2(\theta)[/tex]

Substitute:

[tex]\displaystyle \frac{\sin(\theta)}{1-\sin^2(\theta)}=\frac{\sin(\theta)}{\cos^2(\theta)}[/tex]

Split:

[tex]\displaystyle =\frac{\sin(\theta)}{\cos(\theta)}\left(\frac{1}{\cos(\theta)}\right)=\tan(\theta)\sec(\theta)[/tex]

Therefore, our equation becomes:

[tex]\displaystyle \frac{\sec^2(\theta)-1}{\sin(\theta)}=\tan(\theta)\sec(\theta)[/tex]

From the Pythagorean Identity, we can divide both sides by cos²(θ). This yields:

[tex]\displaystyle \tan^2(\theta)+1=\sec^2(\theta)[/tex]

So:

[tex]\tan^2(\theta)=\sec^2(\theta)-1[/tex]

Substitute:

[tex]\displaystyle \frac{\tan^2(\theta)}{\sin(\theta)}=\tan(\theta)\sec(\theta)[/tex]

Rewrite:

[tex]\displaystyle (\tan(\theta))^2\left(\frac{1}{\sin(\theta)}\right)=\tan(\theta)\sec(\theta)[/tex]

Recall that tan(θ) = sin(θ)/cos(θ). So:

[tex]\displaystyle \frac{\sin^2(\theta)}{\cos^2(\theta)}\left(\frac{1}{\sin(\theta)}\right)=\tan(\theta)\sec(\theta)[/tex]

Simplify:

[tex]\displaystyle \frac{\sin(\theta)}{\cos^2(\theta)}=\tan(\theta)\sec(\theta)[/tex]

Simplify:

[tex]\tan(\theta)\sec(\theta)=\tan(\theta)\sec(\theta)}[/tex]

Hence proven.  

Answer:

5 feet of wall should be on each side of the painting.

Step-by-step explanation:

Given that a 3 foot wide painting should be centered on 13 foot wide wall, to determine how many feet should be on each side of the painting, the following calculations must be performed:

(13 - 3) / 2 = X

10/2 = X

5 = X

Therefore, 5 feet of wall should be on each side of the painting.

Step-by-step explanation:

Area of a triangle = [tex]A=\frac{bh}{2}[/tex]

Where b = base and h = height

The shown triangle has a base length of 3 cm and a height of 8 cm

Using these dimensions we plug in the values into the formula

[tex]A=\frac{3*8}{2} \\3*8=24\\\frac{24}{2} =12\\A=12[/tex]

Hence, the area of the triangle is 12 square centimeters

Answer:

12 centimeters^2

Step-by-step explanation:

We find the area of a triangle by multiplying the base and width of the triangle before dividing by 2

Why because if u put 2 triangles together you get a rectangle

3*8=24

24/2=12

Answer:

B)  x = 7,  y = 4[tex]\sqrt{2}[/tex]

Step-by-step explanation:

you can find the value of 'y' first by connecting the bases with another altitute measuring 4 units

you now have an isosceles triangle where each leg is 4 which makes the hypotenuse equal to 4[tex]\sqrt{2}[/tex]

to find 'x', it is the sum of 3 and 4

A) First, find the volume of each cube:

V = s³

  = (1/2)³

  = 1/8 ft³

We have a total of 64 cubes, therefore the maximum volume will be:

Vmax = 64 · (1/8) = 8 ft³

B) The volume of a rectangular prism is given by:

V = w × l × h

Therefore any combination of w × l × h = Vmax = 8 will be fine.

Since p-value > ∝, H0 is accepted

Step-by-step explanation:

Calculating gives the following results.

Total  20          21927.69 1096.385                                          

1. H0 hypothesis

Since p-value > ∝, H0 is accepted.

Hence the averages of all groups considered to be equal.

Or the difference between the averages of all groups is not big enough to reject H0.

2. P-value

P-value equals 0.999. This means that if we would reject H0, the chance of type1 error (rejecting a correct H0) would be too high i.e  (99.99%)

The bigger  p-value  supports H0.

3. The statistics

The test statistic F equals 0.020, which lies in the accepted range: [-∞ : 2.8477]

Step-by-step explanation:

The caramel apples that are covered with sprinkles are 5.

Arithmetic operation is an elementary part of mathematics that consists of the study of the properties of the traditional operations on numbers—addition, subtraction, multiplication, division, exponentiation, and extraction of roots.

Now it is given that,

Olivia has 150 caramel apples.

Each caramel apple is covered with one topping.

• 2/3 of the caramel apples are covered with peanuts.

• 1/5 are covered with chocolate chips.

• 1/10 are covered with coconuts.

The rest are covered with sprinkles.

Let 'n' be the number of caramel apples are covered with sprinkles.

Thus,we can write

(2/3)*150 + (1/5)*150 + (1/10)*150 + n = 150

100 + 30 + 15 + n = 150

145 + n = 150

⇒ n = 150 - 145

⇒ n = 5

Thus, the caramel apples that are covered with sprinkles are 5.
