19. Find the value of:
4/3tan^2 30° + Sin^2 60° – 3Cos^2 30°+ 3tan^2. 60° - 2tan^2 45°​

Answer:

First, in order to subtract these two fractions you must convert it into improper fractions. For the first one, we can convert it by multiplying the denominator by the whole and adding the numerator which would give you 196/8 for the first one and 157/8 for the second one. This equation would now set up as 196/8-157/8 which would be 39/8 and since you need to convert it back into a mixed fraction we need to know how many times 8 can go into 39 which is 4 so 32 and a remainder of 7. Your answer would be 4 7/8

Step-by-step explanation:

Answer:

9 times.

Step-by-step explanation:

56 multiplied by 9 is 504, and if you add another 56, the number would be greater than 512, so the answer is 9 times.

Answer:

9.14285714286

Step-by-step explanation:

512 ÷ 56 = 9.14285714286

Answer:

1 solution

Step-by-step explanation:

The equation will be a horizontal parabola that has an x-intercept of (-5,0) therefore 1 solution

Answer:

vertex: (-5,0)

axis of symmetry: x=-5

some points: (-7,4)(-6,1)(-5,0)(-4,1)(-3,4)

Answer:

x = 12

Step-by-step explanation:

Here, we want to find the value of x

To do this, we use one of the circle tangent relationships

we have this as:

8^2= 4(4 +x)

8^2 = 16 + 4x

64 = 16 + 4x

64-16 = 4x

4x = 48

x = 48/4

x = 12

Answer:

I don't know bc I can't figure it out sry

An equation is formed of two equal expressions. The negative integer stated in the statement is 1.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the negative integer be represented by -a.

Given that the square of a negative integer has the same value as the sum of that integer plus 2. Therefore, the equation can be written as,

(-a)² = -a + 2

a² = -a + 2

a² + a -2 = 0

a² +2a - a -2 = 0

a(a+2) -1(a+2) = 0

(a-1)(a+2) = 0

a = 1, -2

Since a was a negative integer and we have already used the negative sign in the equation, therefore, the value of a is 1.

Hence, the negative integer stated in the statement is 1.

Step-by-step explanation:

The key understanding here is that there isn't a single way to define "academic achievement." Graduation rate can be a good measure of that. Average SAT is also a good measure. The rate of students who are accepted into college can also be a good measure, but we are not given information about that.

Now let's go over the options and see which of them might be used to describe "academic achievements relative to the budget per student."

Answer:

A good prediction is that the number 5 will be rolled 8 times

Step-by-step explanation:

Here, we want to get the number of times 5 would occur in a roll of 50

firstly, we need the probability of having a 5 come up

To do this, we have to divide the number of 5’s by the count of possible numbers

We have this simply as 1/6

Now, we have to multiply this by 50

we have this as;

1/6 * 50 = 8.333

This is approximately 8

so we have it that in 50 rolls, we can have the number 5 coming up 8 times

Step-by-step explanation:

Kavita is x years old, so 10 years later, her age will be x years plus the next ten. Or, x + 10.

To check this, let's suppose Kavita is 17 years old. In 10 years, she'll be 27.

Substitute the x for our hypothetical age, 17, and our answer, 27, and calculate.

x + 10 = 27

17 + 10 = 27

27 = 27

The equation is true, so we have a true statement. The answer is A, x + 10.

Answer:

Step-by-step explanation:

The equation of a line that is tangent to circle A from point C (9, 8) will be option C; y = x − 1.

If the slope of a line is m and the y-intercept is c, then the equation of that straight line is given as:

y = mx +c

Given; Circle A is located at (6, 5) and has a radius of 3 units.

The slope;

m = (8- 5)/(9 -6) = 1

Substitute in the equation of line;

y = mx +c

8 = 1(9) + c

8 - 9 = c

c = -1

So, We get

y = x − 1

Hence the equation of a line that is tangent to circle A from point C (9, 8) will be option C; y = x − 1.
