Use the distributive property to simplify each expression.
-2(x - 2) + 5x
please help
Answer:
3x + 4
Step-by-step explanation:
Using the distributive property simply means that when there is a number in front of a pair of parentheses, every value inside the parentheses is multiplied by the co-efficient to expand the parentheses.
Here, the coefficient is -2, therefore we multiply both terms inside the parentheses (x and -2) by -2 to expand them:
-2(x - 2) + 5x
= (-2)(x) + (-2)(-2) + 5x
Now we simply evaluate and combine like terms to simplify:
= -2x +4 +5x
= 3x + 4

Find the volume of the prism.
1.2 cm
1.8 cm
2 cm
2.3 cm
The volume is
cubic centimeters.
Answer:
Volume of prism = 6.3 cm³
Step-by-step explanation:
Given:
Dimensions of parallels line = 2.3 and 1.2 cm
Height of prism = 1.8 cm
Width of prism = 2 cm
Find:
Volume of prism
Computation:
Volume of prism = Area of base x Width
Volume of prism = [(1/2)(sum of parallels line)(Height)]Width
Volume of prism = [(1/2)(2.3 + 1.2)(1.8)]2
Volume of prism = [(1/2)(3.5)(1.8)]2
Volume of prism = [(3.5)(1.8)]
Volume of prism = 6.3 cm³

Are machines faster and better at calculating a math equation than mans?
Answer:
MIT economics professor Richard Bookstaber put it simply in his book “The End of Theory”: “No man is better than a machine, and no machine is better than a man with a machine.” ... Humans are too emotion-driven and susceptible cognitive biases, while machines lack an understanding of human thinking.
Answer:
yesThe Liverpool researchers estimate that the robot is able to work 1,000 times faster than a human scientist, and highlight that it is “unlikely a human researcher would have persevered with this multivariate experiment using manual approaches given that it might have taken 50 experiments or 25 days

The result of two Newton's technique iterations to approximation a function's zero using the provided starting guess is 1.5262!
What is a formula that is iterative?Iteration describes carrying out a process repeatedly. To get a new value, start with an initial value and enter it into the iteration formula. To solve an equation using iteration, apply the new value for the subsequent substitution after that, and so on.
By Newton's Method, we have new guess of a zero of a function that are f(x), xn+1, and by using the previous guess, xn, like so-
xn+1 = xn - f(xn)/f'(xn)
and herethe case is [tex]f(x) = cos(x), and so f'(x) = -sin(x).[/tex]
Also, furthermore, [tex]cos(x)/(-sin(x)) = -cot(x).[/tex]
here, we have to simplify the formula to get a better guess for a zero to: xn+1 = xn + cot(xn)
[tex]x1 = 0.6, so x2 = 0.6 + cot(0.6) = 2.06170...\\And x3 = 2.06170... + cot(2.06170...) = 1.52615...\\Ans = 1.5262![/tex]

Step-by-step explanation:
We can set up a proportion: x/12=8/12. We can use cross multiplication to get 12x=96 which would x=8.
The triangles are similar since both of them have 55 degrees as one of the angle measures.

Solve the quadratic by factoring. 3x^{2}+7=-8x+3 3x 2 +7=−8x+3
The roots of the given quadratic equation are x = -2/3 and x = -2.
What is a quadratic equation?A quadratic equation is a equation that is of the form -
y = f{x} = ax² + bx + c
Given is a quadratic equation as follows -
3x² + 7 = - 8x + 3
The given quadratic equations are -
3x² + 7 = - 8x + 3
3x² + 8x = 3 - 7
3x² + 8x + 4 = 0
(x + 2/3)(x + 2) = 0
(x + 2/3) = 0 and (x + 2) = 0
x = -2/3 and x = -2
Therefore, the roots of the given quadratic equation are x = -2/3 and x = -2.

The fries costs $1.49
What is addition?Addition in math is a process of combining two or more numbers.
Given that, Keith ordered a hamburger for $2.25, a medium raspberry ice tea for $1.25, and a small sundae for $1.25. He also ordered French fries. All of these items totalled $6.24.
Let the price of fries be x,
Therefore,
$2.25 + $1.25 + $1.25 + x = $6.24
$4.75 + x = $6.24
x = $6.24 - $4.75
x = $1.49

1.There were 32 brown ducklings at a pond. Twice as
many white ducklings arrived., 1/2 of the brown ducklings
flew away. How many ducklings are there now, at the
pond?
Answer:
80 ducks (16+64)
Step-by-step explanation:
So if there were 32 brown ducks in the pond at first, then twice the amount of brown ducks (32).
32x2=64 white ducks
So now their are 64 white ducks at the pond. We still have to add how many brown ducks their were so…
64+32=96 ducks in total
But then as the white ducks came in half of the brown ducks flew away.
32/2=16 brown ducks left in the pond.
Lastly add the remaining brown ducks with the white ducks and that is you answer!
16+64=80 total amount of ducks
Final Answer:
80 ducks

In each shape there are 4 wholes hence the answer is yes.
What are fractions?A fraction is referred to as the portion of a whole in mathematics. There are two components to a fraction: a numerator and a denominator. The numerator is the number at the top, and the denominator is the number at the bottom.
13a. There are 4 wholes, hence the answer is yes.
13b. Every whole is divided into 2 parts hence the total number of equal parts is 4 *2 = 8. Hence the answer is yes.

Answer:
Y = 3 [tex]\sqrt{2}/2[/tex] And x = 3
Step-by-step explanation:
Because this is a 45 to 45 degree triangle, the 3 * (square root of 2 )/2 is y as well. Because this is a 45-45 triangle, x should be y (Square root of 2). Therefore, replacing y with 3 * (square root of 2 )/2 and multiply the square root of 2, the answer for x is 3. If I got something wrong please tell me, thanks.
What are the values of trigonometric ratios?
three main trigonometry ratios are sin ,cos and tan.
1- Sine or sin θ = perpendicular / Hypotenuse .
2- Cosines or cos θ = base of triangle / Hypotenuse .
3- Tangent or tan θ = perpendicular of triangle / base of triangle.
Trigonometry
Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Trigonometric values are based on the angle theta and the values of the sides of triangle in which the theta angle is made.
for example - value of sin theta is equal to the side opposite to the theta angle divided by hypotenuse of the triangle and we will get the values of the sin trigonometric ratio.

In 2010, the population of a city was 191,000. From 2010 to 2015, the population grew by 3.9%. From 2015 to 2020, it fell by 3.3%. To the nearest 100 people, what was the population in 2020?
Answer:
The population by 2020 is 191,900
Step-by-step explanation:
Given that;
population 2010 (population in 2010): 191000
the population grew from 2010 to 2015: by 3.9%
so, population by 2015 = [tex]191000(1 + \frac{3.9}{100})[/tex]
= [tex]191000(1 + 0.039)[/tex]
= [tex]191000(1.039)[/tex]
= [tex]198449[/tex]
the population drop from 2015 to 2020: 3.3%
so, population by 2015 = [tex]198449(1 - \frac{3.3}{100})[/tex]
= [tex]198449(1 - 0.033)[/tex]
= [tex]198449(0.967)[/tex]
