The solid figure shown here can be formed from which net?​

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: The answer is A

Step-by-step explanation:

Because it said, 2 unshaded parts and 3 shaded parts. And you have to multiply by 2 for 2 and 3

Answer:

12y + 11

Step-by-step explanation:

To add them you would add like terms. That means you would add those with y together and those without together.

8y + 4y + 6 + 5 = 12y + 11

If you want to solve for y, subtract 11 from both sides then divide both sides by 12.

Answer:

Step-by-step explanation:

hello :

(8y + 6) + (4y + 5)=12y+11

Answer is B

Answer:

B

Step-by-step explanation:

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:

x=85

Step-by-step explanation:

The angles are vertical angles, therefore they are congruent. This means we can set them equal to each other.

x+5=90

Solve for x by isolating x. To do this, subtract 5 from both sides

x+5-5=90-5

x=85

So, x=85, and the second choice is correct.

Answer:

It is 85.

Step-by-step explanation:

The angles are vertical from each other so they are equal. 85+5=90.

Answer:

C) -2

Step-by-step explanation:

8 + (-2) = 6

Answer:

52 m

Step-by-step explanation:

a^2 + b^2 = c^2

a^2 + 39^2 = 65^2

a^2 + 1521 = 4225

4225 - 1521 = 2704

Square root of 2704 = 52

Answer:

52m

Step-by-step explanation:

as this is a right angled triangle (has a 90° angle), you can use the Pythagoras theorem to work out the missing side.

Pythagoras theorem:

[tex]a^{2} + b^{2} = c^{2}[/tex]

side A squared (labeled on diagram below)

+ side B squared

= side C squared

for this example though, we don't know the length of side B so we need to swap around the formula.

[tex]c^{2} - a^{2} = b^{2}[/tex]

replace the letters for their numbers,

[tex]65^{2} - 39^{2} = b^{2}[/tex] (calculate)

[tex]65^{2} - 39^{2} = 2704[/tex]  

2704 = b² but we want b by itself so we will square root b² (2704)

[tex]\sqrt{2704} = 52[/tex]

∴ side B = 52m (remember we were calculating in meters)

Answer:true

Step-by-step explanation:

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.

Arrange the data in order from least to greatest

2,3,1,1,0,4

Least to greatest:

0,1,1,2,3,4

Then, find the number in the middle

In this case, there is 2 numbers in the middle, so we will take the average of those 2

1,2

To find the average, add up the numbers and divide by the number of terms

1+2=3

Answer:

400

Step-by-step explanation:

Is means equals and of means multiply

68 = 17% * what number

Change to decimal form

68 = .17 * what number

Divide each side by .17

68/.17 = .17/.17 what number

400 = what number

The number is 400

68 is approximately 17 percent of 400.

To find out what number 68 is 17% of, we can use the following formula:

(17 / 100) x = 68

Let's solve for x:

(17 / 100) x = 68

To isolate x, we can multiply both sides of the equation by (100 / 17):

x = (68 × 100) / 17

x ≈ 400

Therefore, 68 is approximately 17% of 400.

To understand this calculation, think of the percentage as a proportion or ratio. In this case, we are trying to find the ratio of 68 to the unknown number. The result, 0.17, represents how much of the unknown number 68 comprises. By multiplying this ratio by the unknown number, we obtain the value of x, which is approximately 400. Thus, 68 is roughly 17% of 400, indicating that 68 represents 17% of the value 400.

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.

We are to find how long will it take to return to the ground?

Answer:

t = 0.48 sec

Step-by-step explanation:

We are given;

initial velocity; vi = 40 ft/s

hi = 70 ft

acceleration due to gravity; a = 32 ft/s²

Now, we are given that the rocket's height as a function of time is;

h = -12at² + vit + hi

At ground, h = 0

Plugging in the relevant values to obtain ;

0 = -12(32)t² + 40t + 70

-384t² + 40t + 70 = 0

The roots of the equation gives; t = 0.48 sec

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.
