Given:

The equation is:

[tex](5+x)(5-x)=7[/tex]

To find:

The value of A, B and C for the equation's general form.

Solution:

We have,

[tex](5+x)(5-x)=7[/tex]

Using distribution property, we get

[tex](5)(5)+(5)(-x)+(x)(5)+(x)(-x)=7[/tex]

[tex]25-5x+5x-x^2=7[/tex]

[tex]25-x^2=7[/tex]

Taking all terms on one side, we get

[tex]25-x^2-7=0[/tex]

[tex]-x^2+18=0[/tex]

[tex]-(x^2-18)=0[/tex]

[tex]x^2-18=0[/tex]

On comparing this equation with the general form of a quadratic equation [tex]Ax^2+Bx+C=0[/tex], we get

[tex]A=1[/tex]

[tex]B=0[/tex]

[tex]C=-18[/tex]

Therefore, the correct option is 1.

A nurse read the incorrect unit of measurement and gave a patient 100 mg of the tablet.

The patient at risk and she should inform the doctor immediately.

Unitary method is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

Given

Prescription requires 10 mg of tablet.

A nurse read the incorrect unit of measurement and gave a patient .1 g of the tablet.

We know

1 g = 1000 mg

0.1 g = [tex]x[/tex]

⇒ [tex]x[/tex] × 1 = 0.1 × 1000

⇒ [tex]x[/tex] = 100 mg

10 mg < 100 mg

By using unitary method we can say that

A nurse read the incorrect unit of measurement and gave a patient 100 mg of the tablet.

The patient at risk and she should inform the doctor immediately.

Answer:

-9 Degrees is warmer because that number is bigger than -12.

Step-by-step explanation:

Answer:

-9 is warmer

Step-by-step explanation:

Since this negative we want to get closer to zero to be warmer

-12 means you owe 12

-9 means you owe 9

The more you owe means  is further away from zero

Answer:

-104/41

Step-by-step explanation:

f(8) = -13

g(8) = 41/8

f/g(8) = -13/1 / 41/8 = -(13×8) / (41×1) = -104 / 41

f/g(x) = (3-2x) / (1/x + 5) = (3-2x)/1 / ((1+5x)/x) =

= x×(3-2x) / (1+5x) = (3x - 2x²) / (1 + 5x)

for x=8 this gives the same result.

Answer:

It should be in quadrant 1

Step-by-step explanation:

The quadrants of a coordinate plane can be counted counter-clockwise starting from quadrant 1, if you know the exact point you're trying to find, you can use the x and y to figure out which quadrant it's in.

If the x and y values are both positive, the point is in quadrant 1.

If the x value is negative and the y value is positive, the point is in quadrant 2.

If the x and y values are both negative, the point is in quadrant 3.

If the x value is positive and the y value is negative, the point is in quadrant 4.

Answer:

Answer:

190 ft^2

Step-by-step explanation:

So first we need to find which equation we're using and since it's a rectangular prism we're going to use:

2Lw + 2wh + 2Lh

Now what we need to do is plug in the values

2*9*2 + 2*2*7 + 2*9*7

Now just multiply everything and then add it together.

36 + 28 + 126

Once you add everything together you get:

190

The question says to include the correct unit. It says that its feet, but we need to know if its feet squared (^2) or cubed (^3)

If it were area of the whole object, it would be cubed because it is all the area that the object takes up but since it's just the area of the surface it's going to be squared. Therefore, the answer is:

190 ft^2

Answer:

​Robbin's grade point average must be at least 2.75 in order to be unconditionally accepted into the program.

Step-by-step explanation:

An unconditional acceptance into a graduate program at a university will be given to students whose GMAT score plus 100 times the undergraduate grade point average is at least 1075.

This means that:

[tex]x + 100y \geq 1075[/tex]

In which x is the GMAT score and y is the GPA.

Robbin's GMAT score was 800.

This means that [tex]x = 800[/tex]

What must her grade point average be in order to be unconditionally accepted into the​ program?

We have to solve the inequality for y. So

[tex]x + 100y \geq 1075[/tex]

[tex]800 + 100y \geq 1075[/tex]

[tex]100y \geq 275[/tex]

[tex]y \geq \frac{275}{100}[/tex]

[tex]y \geq 2.75[/tex]

​Robbin's grade point average must be at least 2.75 in order to be unconditionally accepted into the program.

Answer:

The probability that a student in this survey says something other than that he or she needs a vacation is:

= 58%.

Step-by-step explanation:

The probability of the teens at the local high school in Oregon who said that they needed a vacation = 42%,

Therefore, the probability that a student in the same survey says something other than that he or she needs a vacation must be 58% (100% - 42%).

Probability calculates the frequency of the occurrences of an event.

Answer:

The answer is below

Step-by-step explanation:

The Angle Addition Postulate states that the measure of an angle formed by two or more angles which are placed side by side is the sum of the measures of the two angles.

Therefore:

∠MON = ∠MOP + ∠NOP (angle addition postulate)

Substituting values gives:

124 = (2x + 1) + (2x + 1)

124 = 2x + 2x + 1 + 1

124 = 4x + 2

subtracting 2 from both sides of the equation:

124 - 2 = 4x + 2 - 2

4x = 122

Dividing through by 4:

4x / 4 = 122 / 4

x = 30.5

Therefore ∠MOP = 2x + 1 = 2(30.5) + 1 = 62°, ∠NOP = 2x + 1 = 2(30.5) + 1 = 62°

∠MOP = 62°, ∠NOP = 62°

Answer:

6 × ¼ is NOT EQUAL TO 6 × ¾

8 × ²/4 is NOT EQUAL TO 6 × ¾

18/(2 × 2) is EQUAL TO 6 × ¾

Step-by-step explanation:

Given 6 * ¾,

We're asked to determine if each of the given expressions is equal or not equal to 6 * ¾.

Let's evaluate 6 * ¾

6 × ¾ = (6×3)/4 = 18/4 = 4.5

Now, let's compare each expression given to determine if it is equal or not

✔️6 × ¼ = (6×1)/4 = 6/4 = 1.5

Therefore,

6 × ¼ is NOT EQUAL TO 6 × ¾

✔️8 × ²/4 = (8×2)/4 = 16/4 = 4

Therefore,

8 × ²/4 is NOT EQUAL TO 6 × ¾

✔️18/(2 × 2) = 18/4 = 4.5

Therefore,

18/(2 × 2) is EQUAL TO 6 × ¾

Answer:

  $80

Step-by-step explanation:

You are given the formula ...

  P = I/(rt)

and the values I = 20, r = 0.05, t = 5.

Put the numbers in place of the corresponding variables and do the arithmetic.

  P = 20/(0.05·5) = 20/0.25 = 80

The amount $80 will generate $20 in interest over 5 years at 5% per year.
