The value of b for the quadratic equation x2 bx 5 = 0 to have two real number solutions is -5.

The standard form of the quadratic equation is,

[tex]ax^2+bx+c=0[/tex]

The quadratic equation has two real number solutions when the value of the following equation is positive.

[tex]b^2-4ac[/tex]

The quadratic equation given in the problem is,

[tex]x^2 +bx+ 5 = 0[/tex]

The value of b has to be found out such that the equation have two real number solutions. For this equation,

[tex]a=1\\c=5[/tex]

Put this value in the above equation as,

[tex]b^2-4\times1\times5\\b^2-20[/tex]

The value of the above expression to be positive, the value of b should be at least 5 or -5.

[tex](-5)^2-20\\25-20\\5[/tex]

Thus, the value of b for the quadratic equation x2 bx 5 = 0 to have two real number solutions is -5.

The answer I got was 88.

Steps: I multiplied 17 by 4 to get 68. Then times 5 by 4 then divided by 2 because it's a triangle then got 10. Do that again for other side and add them together to get 88.

Dependent event is when two events are dependent events, one event influences the probability of another event whereas independent event has no effect on the probability of another event occurring.

↪DEPENDENT EVENT

When two events are dependent events, one event influences the probability of another event. A dependent event is an event that relies on another event to happen first. Dependent events in probability are no different from dependent events in real life. If you want to attend a concert, it might depend on whether you get overtime at work. if you want to visit family out of the country next month, it depends on whether or not you can get a passport in time. More formally, we say that when two events are dependent, the occurrence of one event influences the probability of another event.

Simple examples of dependent events

↪INDEPENDENT EVENT

An independent event is an event that has no connection to another event’s chances of happening (or not happening). In other words, the event has no effect on the probability of another event occurring. Independent events in probability are no different from independent events in real life. Where you work has no effect on what color car you drive. Buying a lottery ticket has no effect on having a child with blue eyes.

When two events are independent, one event does not influence the probability of another event.

Expand the target expression:

A sin(x + ϕ) = A (sin(x) cos(ϕ) + cos(x) sin(ϕ)) = -2 sin(x) + 4 cos(x)

Then we have

A cos(ϕ) = -2

A sin(ϕ) = 4

Recall that sin²(x) + cos²(x) = 1 for all x. Then

(A cos(ϕ))² + (A sin(ϕ))² = (-2)² + 4²

A² (cos²(ϕ) + sin²(ϕ)) = 4 + 16

A² = 20

A = √20 = 2√5

Also recall that tan(x) = sin(x)/cos(x) by definition. Then

(A sin(ϕ)) / (A cos(ϕ)) = 4 / (-2)

tan(ϕ) = -2

ϕ = arctan(-2) = -arctan(2)

Recall that

[tex]\sin(x) = \displaystyle \sum_{n=0}^\infty (-1)^n \frac{x^{2n+1}}{(2n+1)!}[/tex]

which converges for all real x. (One can show this with the ratio test, for instance.)

Then

[tex]\sin\left(x^4\right) = \displaystyle \sum_{n=0}^\infty (-1)^n \frac{\left(x^4\right)^{2n+1}}{(2n+1)!} = \boxed{\sum_{n=0}^\infty (-1)^n \frac{x^{8n+4}}{(2n+1)!}}[/tex]

By the ratio test,

[tex]\displaystyle \lim_{n\to\infty} \left|\frac{(-1)^{n+1} x^{8(n+1)+4}}{(2(n+1)+1)!} \times \frac{(2n+1)!}{(-1)^n x^{8n+4}}\right| \\\\ = x^8 \lim_{n\to\infty} \frac{(2n+1)!}{(2n+3)!} \\\\ = x^8 \lim_{n\to\infty} \frac1{(2n+3)(2n+2)} = 0[/tex]

Step-by-step explanation:

35% of 242 would be 84.7%

We know this because we simply have to solve it!

We solve it by doing:

(35/100)*242  

(35*242)/100

= 8470/100 = 84.7

We need to determine 35% of 242 now and the procedure explaining it as such

Step 1: In the given case Output Value is 242.

Step 2: Let us consider the unknown value as x.

Step 3: Consider the output value of 242 = 100%.

Step 4: In the Same way, x = 35%.

Step 5: On dividing the pair of simple equations we got the equation as under

242 = 100% (1).

x = 35% (2).

(242%)/(x%) = 100/35

Step 6: Reciprocal of both the sides results in the following equation

x%/242% = 35/100

Step 7: Simplifying the above obtained equation further will tell what is 35% of 242

x = 84.7%

Therefore, 35% of 242 is 84.77

Answer:

$52.5

Step-by-step explanation:

Since 25% is the sale, we subtract 100% (the whole) by the discount, 25%. That leads us to say that we are paying for 75% of the product's price.

We multiply $70 by 0.75 and you get $52.5!

The solution to the absolute-value inequality is x > 9; and x < -1

An inequality is an expression that shows the nonequal comparison of two or more numbers and variables.

Let x represent the unknown number, hence:

|x - 4| > 5

(x - 4) > 5; and -(x - 4) > 5

x > 9; and x < -1

The solution to the absolute-value inequality is x > 9; and x < -1

Step-by-step explanation:

Finding the range is simple, just do 29-5 and you will get 24.

For the july one same applies 24-5=19

24-19 is 5 so It is 5  more than the range for July.

For the median, it is the middle data set meaning you will do 17-10 which is 7 meaning New years is 7 more than July.

Interquartile is For new years 12-17

The Interquartile range for July is 7-10 which means that is 5-3 which is 2 more of a range.
