Find the area of figure above. Use 3.14 for pi.

Answer:

1. 1.685

2. 16.828

Step-by-step explanation:

1. log_5 15

To evaluate this logarithm you use the following formula:

[tex]Log_ab=\frac{log_{10}b}{log_{10} a}[/tex]

by replacing you obtain:

[tex]log_5 15=\frac{log_{10} 15}{log_{10}5}=\frac{1.176}{0.698}=1.685[/tex]

hence, the answer is 1.685

2. -3ln(1/e4/5)

to solve this logarithm you use the following properties:

[tex]ln(a^m)=m\ ln(a)\\\\ln(\frac{a}{b})=ln(a)-ln(b)\\\\ln(e^m)=m[/tex]

[tex]ln(1)=0[/tex]

By applying all these properties you obtain:

[tex]-3ln(\frac{1}{\frac{e^4}{5}})=-3[ln(\frac{1}{e^4})-ln(5)]=-3[ln(1)-ln(e^4)-ln(5)]\\\\-3ln(\frac{1}{\frac{e^4}{5}})=-3[0-4-1.609]=16.828[/tex]

hence, the answer is 16.282

Answer:

  4 cm

Step-by-step explanation:

The ratios of sides in a 30-60-90 triangle are ...

  1 : √3 : 2

The hypotenuse is double the length of the shortest side, so is 4 cm in your triangle.

Final answer:

In a 30-60-90 triangle, if the shortest side is 2 cm, the hypotenuse is twice that length, resulting in a hypotenuse of 4 cm.

Explanation:

The 30-60-90 right triangle has sides in a specific ratio. The lengths of the sides opposite the 30°, 60°, and 90° angles are in the ratio 1:√3:2. If the shortest side is 2 cm, which is opposite the 30° angle, the hypotenuse is twice the length of the shortest side because it is opposite the 90° angle. Therefore, the length of the hypotenuse is 4 cm.

Answer:    

Answer is B

Answer:

B

Step-by-step explanation:

Answer:

x = ±11

Step-by-step explanation:

x^2 =121

Take the square root of each side

sqrt(x^2) = ±sqrt(121)

x = ±11

Answer:

x=±11

Step-by-step explanation:

To solve, we need to isolate the variable x,

To do this, take the square root of both sides

[tex]x^{2} =121\\\sqrt{x^{2} } =\sqrt{121}[/tex]

x=±11

It is positive or negative 11 because 11^2 (11*11)=121, but -11^2 (-11*-11) also equals 121 because 2 negatives multiplied become a positive.

Answer:

6xy² + 10y²z

Step-by-step explanation:

I did it and I got it right

28 m/s is the velocity , when it is going after 4.0 seconds.

When a point or an object moving in a straight line , the acceleration is the rate at which velocity changes with time, in terms of both speed and direction.

Here, given that,

A car is moving at a constant acceleration of 7.0 m/s/s

Now, we have,

Velocity = acceleration * time

After 4 sec. = 7*4 = 28 m/s

Hence, 28 m/s is the velocity , when it is going after 4.0 seconds.

Answer:

D. the diagonals bisect each other

Final answer:

The property of all squares is that their diagonals bisect each other. Other options are incorrect as squares have parallel and congruent sides as well as congruent angles. Therefore, the correct answer is D.

Explanation:

The question asks which of the following is a property of all squares. The correct answer is option D: The diagonals bisect each other. In every square, this property holds true, as squares are a type of rectangle, and in rectangles, the diagonals are congruent and bisect each other. We know that a square has four equal sides and four equal angles, which are right angles.

This implies that not only are the diagonals congruent, but they also divide the square into four congruent right triangles, bisecting one another at their midpoint. Options A, B, and C describe properties that are incorrect for squares, as all sides of a square are parallel and congruent, and all angles are congruent as well.

The first one uses the distributive property, after which you have the second expression. She runs two miles per day (one in the morning and the other in the evening) and she does 20 push-ups per day (a set of 10 in the morning and a set of 10 in the evening). m represents miles and p represents push-ups.

Answer: 681 square inch

Step-by-step explanation:

Hi, we have to apply the formula for the surface area:

A = 2wl + 2lh + 2hw

Where:

w: width

l: length

h: height

Replacing with the values given:

A = (2x12x18.25) + (2x12x3)+(2x18.25x3)

A= 438+72+109.25

A=619.5 in2

Since it has to be 10% more than the surface.

619.5 x (10/100) = 61.95 in2

Adding that value to the surface area

619.5+61.95 = 681.45in2 = 681 in2

Answer:  a) x= 68, b) 108°, c) 72°, d) 255°.

Step-by-step explanation:

Since we have given that

The interior angles of hexagon:

(2x+17), (3x - 25), (2x+49),  (x+40), (4x-17) and (3x - 4).

So, it becomes :

[tex]2x+17+3x-25+2x+49+x+40+4x-17+3x-4=1080\\\\15x+60=1080\\\\15x=1080-60\\\\15x=1020\\\\x=68[/tex]

ii. Find the smallest interior angle of the quadrilateral.

[tex]x+40=68+40=108^\circ[/tex]

iii. Find the largest exterior angle of the quadrilateral.

[tex]180-108=72^\circ[/tex]

iv. Find the largest interior angle of the quadrilateral.

[tex]4x-17=4\times 68-17=255^\circ[/tex]

Hence, a) x= 68, b) 108°, c) 72°, d) 255°.

Answer:

18

Step-by-step explanation:

1,017.36 is the area of the circle and you need to find the radius

area formula : 3.14rsquared

so the formula you are going to solve for your answer is 3.14rsquared=1,017.36

divide by 3.14

rsquared = 324

un square it to get you radius which is 18

you didnt clarify whether you wanted radisu or diameter so ill give both

R: 18

D:36

Answer:

The sprinkler can spread water up to 36 feet away!

Step-by-step explanation:

First, identify the formula used to find the area of a circle:

Area = pi x r^2

We already know the area that the sprinkler makes, so just plug that in! Then, we just need to reverse engineer the formula!

1,017.36 square feet = pi x r^2

1,017.36 square feet= 3.14 x r^2

1,017.36/3.14 = r^2

324 = r^2

sqrt of 324 = 18

So, we figured out that the radius of the circle is 18 feet! Now, remember the radius is just half the amount of the diameter!

18 x 2 = 36 feet

The most elegant form to describe the given numbers would simply be

$=1*2^x

You start with one, eich doubles after a day (x=1). x is the number of days and how often you multiply by 2

Answer: 3(-1) - 4(-1) = 1.

We are given that y = 4x and the equation is 3x - y = 1.

We need to evaluate.

3x - y = 1

3(-1) - 4(-1) =

-3 minus -4 = 1.

Final answer:

Explains how to solve a system of two linear equations by substitution.

Explanation:

The provided equations are:

y = 4x

3x - y = 1

To solve the system of equations, we can substitute the value of y from the first equation into the second equation:

Therefore, the solution is x = -1 and y = -4.
