Solve for the value of c (2c-4) (5c+3)

Answer:

-4±2√3

Step-by-step explanation:

quadratic formula: (-b±√(b²-4ac))/(2a)

a = 1

b = 8

c = 4

(-8±√(8²-4*1*4))/(2*1)

(-8±√(64-16))/(2)

(-8±√48)/(2)

(-8±4√3)/(2)

-4±2√3

The exponential function  can be written as y = 700e^-0.094t.

We know that the term function would have to do with a mathematical rule that we can use to be able to obtain specific values. Now we have to know that there was a sample of 700 milligrams of a radioactive substance to start a study. Since then, the sample has decayed by 9.4% each year.

We can use;

N = Noe^-rt

N = amount at time t

No = Amount at the beginning

r = decay rate

t = time taken

Thus we have; y = 700e^-0.094t

Answer:36,000

Step-by-step explanation: if ten percent of 100 is 10 we can use the same concept on 40000 by dividing it by 10 because 10% can be roughly said as 1/10 so 1/10 of 40000 is 4000 which we will subtract 40000 by which results in 36000

Answer:

2/52 + 2/52 = 4/52

Answer:

Your answer for both is 31 degrees

Step-by-step explanation:

Because they are similar we know their angles are the same. If you know the rule about triangles' interior angles always add up to 180, then you can just easily find this out.

First you do

82+67 = 149

Take that answer and minus it by 180

180-149 = 31

Answer:

*Using < for angle symbol*

m<E= 61 degrees

m<G= 119 degrees

Step-by-step explanation:

Because the two triangles are similar (meaning they have either length of sides or angle measurements in common, we can assume that they have the same angles because they are not the same size. We know that m<A= 82 degrees, which means so will m<D. You add the 82 and the 37 (from m<F) together to find 119. You subtract this from 180 (the total angle measurement of a triangle) to find m<E= 61. To find m<G, you subtract the 61 from 180, the angle measurement of a straight line, to find 119.

Hope this helps! Have a nice day :)

On solving the question, we can say that - the probability of given will be P(a/c) = 3/6 = 1/2

A branch of mathematics known as probability measures the possibility of an event happening or a proposition being true. The probability of an occurrence is a number between 0 and 1, where roughly 0 denotes the event's improbability and 1 denotes certainty. A probability is a numerical representation of the possibility or probability that a specific event will take place. Probabilities can alternatively be stated as percentages ranging from 0% to 100%, or as percentages from 0 to 1. the proportion between the number of events in a comprehensive collection of equally likely outcomes that lead to a certain occurrence and the entire number of outcomes.

here,

the probability that event the dice will roll is 6

and chances of geting even numbers are = 3

The time taken to make and pack an order represented by the equation ; 2x + 10. How man minutes will it take to make and pack an order for 36 parts:

Answer:

82 minutes

Step-by-step explanation:

Time taken to make and pack an order : 2x + 10

To pack 36 orders ; put x = 36 in the equation :

= 2(36) + 10

= 72 + 10

= 82

82 minutes is required to make and pack an order for 36 parts.

Answer:

2x + 10

= 2(36) + 10

= 72 + 10

= 82

It will take 82 minutes to make and pack an order for 36 parts.

Given:

A figure of a circle. A secant SU and a tangent SR is drawn to the circle from the external point S.

To find:

The measure of the line segment TU.

Solution:

According to the secant tangent segment theorem, the square of tangent is equal to the product of secant and external segment of the secant.

Using secant tangent segment theorem, we get

[tex]SR^2=SU\times ST[/tex]

[tex](40)^2=(32+2x-2)\times (32)[/tex]

[tex]1600=(30+2x)(32)[/tex]

[tex]1600=960+64x[/tex]

Subtract both sides by 960.

[tex]1600-960=64x[/tex]

[tex]640=64x[/tex]

Divide both sides by 64.

[tex]\dfrac{640}{64}=x[/tex]

[tex]10=x[/tex]

Now, the measure of the line segment TU is:

[tex]TU=2x-2[/tex]

[tex]TU=2(10)-2[/tex]

[tex]TU=20-2[/tex]

[tex]TU=18[/tex]

Therefore, the correct option is C.

The miles per hour that the car is going after 8.55 seconds is 610.79 miles per hour.

From the information Illustrated, it should be noted that the t in seconds that it takes a car to accelerate to ask mph can be described by T = 0.001 × 0.732X² + 15.417X + 603.738.

In this case, it is important to note that x in the function simply represents the seconds.

Therefore, based on the information, the miles per hour is the car going after 8.55 seconds will be:

T = 0.001 × 0.732X² + 15.417X + 603.738.

T = 0.001 × 0.732(8.55)² + 15.417(8.55) + 603.738

T = 0.001 × 53.511 × 131.815 + 603.738

T = 610.79

Answer:

9.9 inches

Step-by-step explanation:

Use the pythagorean Theorem

c^2 = a^2 + b^2

c^2 = 7^2 + 7^2

c^2 = 49 + 49

c^2 = 98

Take the square root of both sides

c = 9.8994949366

Rounded

c = 9.9 inches

The expression that represents the price of the video game after the discount is

p - 0.4p
Where p is the original price of the video game.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Price of the video game = p

Discount = 40%

The price of the video game after the discount.

= p - (40% of p)

= p - (40/100)p

= p - 0.4p

Thus,

The expression is p - 0.4p.

Step-by-step explanation:

Answer:

A.) negatively skewed

B.) Symmetric

C.) Positively skewed

Step-by-step explanation:

The shape of a distribution can be described in terms of the tail and peak of the distribution as Symmetric, left tailed or right tailed.

In the first graph; distribution is left tailed as we have a longer tail to the left Than to the right side of the distribution and the peak Hence, slightly shifting to the right.

The second graph on the other hand sees the peak being centered, at the centre of the distribution and the tails being even. Hence, we have a Symmetric or normal distribution.

The third is the opposite of the first with the tail being to the right and peak slightly shifting to the left to give a positive skew or right tailed distribution.
