Answer:

Acute Triangle

Step-by-step explanation:

Angles in a triangle add up to 180 degrees.

So,

x+2x+2x = 180

=> 5x = 180

Dividing both sides by 5

=> x = 36

So, The lengths are:

=> 36

=> 72

=> 72

Since all the angles are less than 90 degrees, It is an acute triangle.

Answer:

Surface are = 94.24 cm2

Cylinders =4,244

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Surface area of a cylinder = 2π (diameter/2) h + 2π (diameter /2)²  

Replacing with the values given

s = 2π (2/2) 14 + 2π (2/2)²

s = 87.96+ 6.28 =94.24 cm2

Since:

1 m2 = 10,000 cm2

40 m2 = 400,000 cm2 (area that one can of paint covers)

We have to divide the area that one can of paint covers by the surface area of each cylinder:

400,000/94.24 = 4244 cylinders

Answer:

308, 398, 421, 433, 570

Step-by-step explanation:

To start we know the smallest is 308 cans, so that is the first class.

Next, it says the range is 262. The range is maximum minus the minimum. Since we know the minimum(308), that means 308 + 262 = 570 and 570 is the maximum or the class with most collected cans.

Then, it says the median or the middle number is 421, the middle number in a class is 3. So, the third class collected a total of 421 cans.

After that, it says the two classes in the three hundred, or the first and second class, has a total of 706 cans. So, if we do 706 - 308 we get the second class. Which collected 398 cans.

Finally, it says the total all the class collected is 2130. So, if we add all the values we have know and subtract it from the total of all the class we get the missing class or the fourth class. So, 308 + 398 + 421 + 570 = 1697, and 2130 -1697 = 433. Which the fourth class.

Least to greatest:

308

Have an awesome week!

The solution is, the true solution to the equation below is x=4.

Logarithm, the exponent or power to which a base must be raised to yield a given number. The quotient rule says that, the logarithm of a quotient is equal to a difference & the product rule says that logarithm of product is equal to the sum of logarithm.

Formula to be used,

log⁡〖(ab)=log⁡a+log⁡b 〗

〖log(〗⁡〖a/b)=log⁡a-log⁡b 〗

here, we have,

the given equation is,

㏑[tex]e^{ln( x)}[/tex] + ㏑[tex]e^{ln (x^{2}) }[/tex] = 2㏑8

or,  ㏑x * ㏑ e + ㏑x² * ㏑e = 2㏑ 8

or, ㏑x +  ㏑x² = 2㏑ 8

or, ㏑( x*x²) = ㏑ 8²

or, ㏑x³ = ㏑ 64

now, taking out the nature logarithm from both sides, we get,

x³ =  64

or, x = 4

Hence, The solution is, the true solution to the equation below is x=4.

He will require 2.79 cubic feet of potting soil to fill the planter, which is a rough estimate.

The product of a cylinder's base area and height provides the formula for calculating the cylinder's volume. A cylinder's volume is equal to πr²h cubic units.

Given, A gardener has a cylindrical planter that has a diameter of 16 inches and is 2 feet deep.

From the general formula of volume of cylinder =  πr²h cubic units

in our case

r = 16 / 2 = 8 inches

Since 1 feet = 12 inches

r = = 8/12 feet = 2/3 feet

h = 2 feet

The volume of platter = π * 2/3 * 2/3 *2

The volume of the platter = 2.79 ft³

Therefore, the approximate number of cubic feet of potting soil that he will need to fill the planter is 2.79 ft³.

Step-by-step explanation:

Answer:

B. y ≥ 1/3 x - 1  

Step-by-step explanation:

y =  mx + b

b = - 1,

m = rise/ run = 1/3

y = 1/3 x - 1  is equation of the line.

Shading is over the line, so

y ≥ 1/3 x - 1  

Answer:

a = 50t

Step-by-step explanation:

The graph goes through (0,0) so the y intercept is 0

a=5t

a=50t

a=50 + t    not it

a=10t ​

The slope is  y/x since the y intercept is 0

m = 50/1 = 50

The equation for the line is

y = 50x+0

y = 50x

Using the variables given

a = 50t

Answer:

the graph corresponds to function "D"  [tex]f(x)=3\,(\frac{1}{5} )^x[/tex]

Step-by-step explanation:

Since the graph shown corresponds to an exponential "decay" (the function decreases as we move from left to right), the base of the exponent has to be a number smaller than 1 (one). So we examine the only two options that give such (options C and D which have fractions as the base - 1/3 and 1/5 respectively)

From there, we analyze which of the two functions satisfies the crossing of the y-axis at (0,3) which is clearly shown in the graph:

We study both:

function C at x = 0 gives:

[tex]f(x)= 5\,(\frac{1}{3})^x\\f(0)=5\,(\frac{1}{3})^0 \\f(0)=5\,(1)\\f(0)=5[/tex]

while function D at x = 0 gives:

[tex]f(x)= 3\,(\frac{1}{5})^x\\f(0)=3\,(\frac{1}{5})^0 \\f(0)=3\,(1)\\f(0)=3[/tex]

Therefore, the graph corresponds to function "D"

A correct option is an option (d)

From the given graph the function is increasing, therefore the base of the exponent must be greater than 1

And the best suited is the first, as it passes through the point,

y = 3

If you substitute x = 0 in the function result you have to give,

y = 3 and intersect the y-axis at that point

So, the required function is [tex]f(x)=3\times (\frac{1}{5} )^x[/tex]

Answer:

We are given:

Putting values in above equation, we get:

Hence, the slope of the line is coming out to be 0.

Step-by-step explanation:

The slope of the line that contains the points (3, -2) and (7, -2) is 0.

Option A is the correct answer.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

Points:

(3, -2) and (7, -2)

Answer:

Option (2), (3) and (4)

Step-by-step explanation:

Let the equation of the line representing the given table is,

y - y' = m(x - x')

where 'm' = slope of the line

(x', y') is the point lying on the line.

Let the two points (-6, -10) and (-4, -9) lie on the line

Slope 'm' = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

               = [tex]\frac{-9+10}{-4+6}[/tex]

               = [tex]\frac{1}{2}[/tex]

Equation of the line passing through (-4, -9) with slope [tex]\frac{1}{2}[/tex] will be

y - (-9) = [tex]\frac{1}{2}(x+4)[/tex]

y + 9 = [tex]\frac{1}{2}(x+4)[/tex]

Equation of the line passing through (-6, -10) with slope = [tex]\frac{1}{2}[/tex]

y - (-10) = [tex]\frac{1}{2}(x+6)[/tex]

y + 10 = [tex]\frac{1}{2}(x+6)[/tex]

Equation of the line passing through (6, -4) and slope =  [tex]\frac{1}{2}[/tex]

y + 4 = [tex]\frac{1}{2}(x-6)[/tex]

Therefore, Options (2), (3) and (4) will be the answer.
