Answer:

  E

Step-by-step explanation:

The general term matches the form ...

  an = a1 +d(n -1)

for a1 = 7 and d = 3.

This is the form for the general term of an arithmetic sequence with first term 7 and each successive term 3 more than the previous one.

That description matches the recursive formula ...

  a(1) = 7; a(n) = a(n-1) +3 . . . . . choice E

Answer:

x = [tex]3\sqrt{13}[/tex] = 10.8

Step-by-step explanation:

Both problems are done the same way.  I will do the first one and you do the second one.  OK?

Move the radius x to make a right triangle.  The 6 unit segment bisects the chord.  So, the legs of the right triangle are 6 and 9

The use the Pythagorean theorem to find x, which is the hypotenuse of the right triangle.   Now,

[tex]6^{2} + 9^{2} = x^{2}[/tex]

[tex]x^{2} = 36 + 81 = 117\\x = \sqrt{117} = 3\sqrt{13}[/tex]= 10.8

None of the answer choices are to the nearest tenth.  So, I am confused about that.

In  the second problem, the answer should be 11.2

Answer:

-36

Step-by-step explanation:

replace x with -5 and solve for the parenthesis and then take that number which would be -16 and multiply it by 9 which then would give you -144.  So then you would take -144 and divide it by 4 and your answer would be -36.

Answer:

1/2 and 3

Step-by-step explanation:

The quadratic formula is as given:

 (  -b±√(b^2-4ac)  )/2a

To use it, plug in the a,b and c values.

ax^2+bx+c

In this case a is equal to 2, b is equal to -7, and c is equal to 3

plugging it into our formula gives us:

(-(-7)±√(-7^2-4*2*3)  )/2*2

Which is equal to:

7±√(49-24) / 4

= 7±√25 / 4

=7±5 / 4

=2/4, 12/4= 1/2, 3

Answer:

7

Step-by-step explanation:

The leading coefficient of the given expression is 7.

A coefficient is a factor that is multiplied by a variable or a term in an expression. It can be a number or a symbol representing a constant value. For example, in 7x - 3y + 5, the coefficients are 7, -3, and 5.

Given that a quadratic function f(x) = 6-x+7x², we need to find the leading coefficient,

So, rearranging the terms in the function in standard form,

f(x) = 7x²+x-6

The leading coefficient is the coefficient of the term with the highest power or degree in a polynomial,

Here, the highest power coefficient is 7.

Hence, the Leading coefficient of the given expression is 7.

Answer: (-2, 4)

Answer:

2, 4

Step-by-step explanation:

2, 4 or 4, 2 because its either the same or oppisote

Answer:

See below

Step-by-step explanation:

When a graph is symmetric about the origin, it is an odd function (Ex: y=x³)

When a graph is symmetric about the y-axis, it is an even function (Ex: y=x²)

A function is considered even if f(x) = f(−x) and it is considered odd if f(-x)=-f(x).

A function is considered even if f(x) = f(−x) and it is considered odd if f(-x) = - f(x).

Odd Function - A true function f(x) is said to be an odd function if the output value of f(-x) is the same as the negative of f(x) for all values of x in the domain of f.

The equation should be stored in an odd function:

f(-x) = -f(x)

Even Function - A true function f(x) is said to be an even function if the output value of f(-x) is the same as the f(x) for all values of x in the domain of f.

The equation should be stored in an even function:

f(-x) = f(x)

When a graph is symmetric about the origin, it is an odd function.

When a graph is symmetric about the y-axis, it is an even function.

A function is considered even if f(x) = f(−x) and it is considered odd if f(-x) = - f(x).

Answer:

Well the first mesurement is 66 degreess and the second one will be 90 degress because it shows the 90 angle on the screen so the last one will be 180-90-66 which will equal 24 degreess

Step-by-step explanation:

In short 24 degress.

The ball will be 48 feet above the ground at the times of

1 second and 3 seconds.

The quadratic function for this problem is defined as follows:

h = -16t² + 64t.

The ball is 48 feet above the ground when h(t) = 48, hence:

-16t² + 64t = 48.

16t² - 64t + 48 = 0.

The equation can be simplified by 16 as follows:

t² - 4t + 3 = 0.

Factoring the expression, we have that:

(t - 3)(t - 1) = 0.

Applying the Factor Theorem, the times are given as follows:

To go from circle A to B, we apply a translation of <-5, -5> and a dilation of scale factor k = 2.

The equation for circle A is:

(x + 2)^2 + (y - 4)^2 = 4^2 =  16

The equation for circle B is:

(x - 3)^2 + (y - 9)^2 = 8^2 = 64

So, if we start with circle B, we need to apply a translation of <-5, -5> to go to the center of B, then if we apply a dilation of scale factor K, the radius of the circle becomes 4*k.

Particularly of k = 2, we get:

4*2 = 8

So the scale factor k = 2 transforms the radius from 4 to 8.

Finally, if we apply these two transformations to circle A, we get circle B, which means that the circles are similar.

Answer:

2.5 hours

Step-by-step explanation:

The total amount of time studying by students who spent 1/2 an hour studying is the product of the number of students who spent 1/2 an hour studying by 1/2 an hour.

Hence, counting the number of dots on the point marked 1/2 gives the count of students who spent 1/2 an hour studying and multiply this number by 1/2.

Total amount of hours spent = 1/2 * 5 = 2.5 hours
