To solve these you expand the polynomial and use the FOIL method.

The car's speed after the given amout of time is 19.8 m/s²

The rate at which an object's velocity with respect to time changes is referred to as acceleration in mechanics. They are vector quantities, accelerations. The direction of the net force acting on an object determines the direction of its acceleration. A point or object going straight ahead is accelerated when it accelerates or decelerates. Any alteration in an object's velocity could take the form of a change in direction of motion or a speed increase or reduction. The moon orbiting the earth, an apple falling to the ground, and a car stopped at a stop sign are a few instances of acceleration.

Average Acceleration =Change in Velocity/ Time Taken

So Change in Velocity is 10-x m/s

Time taken is 7.25 s

Given accelaration 4.11 m/s²

Putting the values we get,

4.11 = (10-x)/7.25

⇒29.8 = 10-x

⇒x=19.8 m/s²

The value of the expression (3x^5 + y^2)^2 is 9x^10 + 6x^5y^2 + y^4

The expression is given as:

(3x^5 + y^2)^2

Expand the expression

So, we have

(3x^5 + y^2)^2 = (3x^5 + y^2)(3x^5 + y^2)

Expand the bracket

(3x^5 + y^2)^2 = 9x^10 + 3x^5y^2 + 3x^5y^2 + y^4

Evaluate the sum

(3x^5 + y^2)^2 = 9x^10 + 6x^5y^2 + y^4

Hence, the value of the expression (3x^5 + y^2)^2 is 9x^10 + 6x^5y^2 + y^4

Answer:

x = 2

Step-by-step explanation:

Simplifying

90 = 10(x + 7)

Reorder the terms:

90 = 10(7 + x)

90 = (7 * 10 + x * 10)

90 = (70 + 10x)

Solving

90 = 70 + 10x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-10x' to each side of the equation.

90 + -10x = 70 + 10x + -10x

Combine like terms: 10x + -10x = 0

90 + -10x = 70 + 0

90 + -10x = 70

Add '-90' to each side of the equation.

90 + -90 + -10x = 70 + -90

Combine like terms: 90 + -90 = 0

0 + -10x = 70 + -90

-10x = 70 + -90

Combine like terms: 70 + -90 = -20

-10x = -20

Divide each side by '-10'.

x = 2

Simplifying

x = 2

Answer: 136, 625,532,413

Step-by-step explanation:

The coordinate of point c is such that point c is 7/8 of m to j is [ 7/8(x₂ - x₁),  7/8(y₂ - y₁) ].

A pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane. typically expressed by the x-value and y-value pairs (x,y).

Coordinates are always written in the form of small brackets the first term will be x and the second term will be y.

For example (5,3) here 5 will be for the x and 3 will be for the y.

Another example is (9,0) here 9 is for x and 0 is for y.

Let's say the coordinate of m → (x₁,y₁)

j → (x₂ ,y₂)

Now since point c is proportion with 7/8

So,

It will be 7/8 times of difference between of x and y coordinate of points m and j

So,

x = 7/8(x₂ - x₁) and y = 7/8(y₂ - y₁)

Hence "The coordinate of point c is such that point c is 7/8 of m to j is [ 7/8(x₂ - x₁),  7/8(y₂ - y₁) ]".

Answer:

60>x>25

Step-by-step explanation:

The number of years to the nearest hundredth is t = 21 years and 3 months.

It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.

We can calculate the compound interest using the below formula:

[tex]\rm A = P(1+\dfrac{r}{n})^{nt}[/tex]

Where A = Final amount

          P = Principal amount

          r  = annual rate of interest

          n = how many times interest is compounded per year

          t = How long the money is deposited or borrowed (in years)

It is given that:

A = $25,600

P = $29,00

r = 10.4 = 0.104

n = 4

[tex]\rm 25600 = 2900(1+\dfrac{0.104}{4})^{4t}[/tex]

After solving:

t = 21.212 years

Or

t = 21 years and 3 months

Thus, the number of years to the nearest hundredth is t = 21 years and 3 months.

The complete question is:

How long will it take for $2900 to grow to $25,600 at an interest rate of 10.4% if the interest is compounded quarterly round the number of years to the nearest hundredth?

===================

Given equation:

Multiply all terms by 7 to get rid of fraction:

Solving for the value of x,

→ (3/7)x - (4/7) = -1/7

→ (3x - 4)/7 = -1/7

→ 3x - 4 = (-1/7) × 7

→ 3x - 4 = -1

→ 3x = -1 + 4

→ x = 3/3 = 1

Hence, the value of x is 1.

The Probability of not occurring of that event is 0.73.

Simply put, probability is the likelihood that something will occur.

When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.

Flipping a coin is the best illustration for understanding probability:

Heads or tails are the two possible results.

What is the likelihood that the coin will land on heads? P(H) = can be used to determine this. P(H)=? P, H, the equals sign, the left and right parenthesis, and the question mark. It's possible that you already know 50%, or half and half, is the likelihood. How do we figure it out, though?

Probability of an event = (number of possible outcomes) / (total number of outcomes)

we know , total probability is always 1

Total probability = pro. of event occur + prob. of event not occur

1 = 0.27 + event not occur

probability of event not occur is 0.73

The equation which represents the number of triangles is 1/3 the number of sides is t = (1/3) × s.

Let's denote the number of sides of a polygon as "s" and the number of triangles that can be formed within the polygon as "t."

The equation for the number of triangles being 1/3 the number of sides is:

t = (1/3) × s

This equation states that the number of triangles (t) is equal to one-third of the number of sides (s) in a given polygon.

Hence, the equation which represents the number of triangles is 1/3 the number of sides is t = (1/3) × s.

Answer:

36/5 as a decimal is 7.2

Step-by-step explanation:

In the fraction 36/5, 36 is the numerator and 5 is the denominator, the fraction bar means "divided by". Therefore, the fraction 36/5 is same as "36 divided by 5" or "36 ÷ 5".

When we calculated 36 divided by 5, we found that 36/5 in decimal form is:

36 ÷ 5 = 7.2

Therefore, the decimal form of 36/5 is 7.2
