Answer:

[tex]\text{C. }a_n=-8+(n-1)5[/tex]

Step-by-step explanation:

The explicit formula for an arithmetic sequence is given by [tex]a_n=a_1+(n-1)d[/tex], where [tex]a_n[/tex] is the [tex]n[/tex]th, [tex]a_1[/tex] is the first them of the sequence, and [tex]d[/tex] is the common difference.

In the given sequence -8, -3, 2, 7, we can see that we're adding 5 to each term. Therefore, the common different is positive five (+5). We can also identify the first term is -8. Therefore, we have:

Thus, the explicit formula for this sequence is:

[tex]\boxed{a_n=-8+(n-1)5}[/tex]

Answer

f(-2)= 12

Step-by-step explanation:

f(x) = -3x2

f(-2)= -3 (-2) 2

f(-2)= 6.2

f(-2)= 12

Hope this help :)

Answer:

-12

Step-by-step explanation:

f(x) = -3x^2

f(-2) = -3(-2)^2 = -12

Answer:

The zeros of the function will be when f(x) = 0. As 0 = 3x^2 - 7x + 1, you can use the quadratic formula to solve, finding that x = (7 + sqrt(37))/2 or (7 - sqrt(37))/2.

Answer:

a^2 -10a +16

Step-by-step explanation:

(a-2) • (a-8)

FOIL

first a*a = a^2

outer: a * -8 = -8a

inner: -2 *a = -2a

last: -2 *-8 = 16

Add them together

a^2 -8a -2a+16

Combine like terms

a^2 -10a +16

Answer:

Step-by-step explanation:

(a-2) (a-8) , distribute a over (a-8) then -2 over (a-8)

a²-8a-2a+16, combine like terms

a² -10a +16

Answer:

DC = 2

Step-by-step explanation:

From the diagram, AD (i.e the angle bisector) bisects the angle into 2 equal parts. Thus, BD and DC are equal.

BD = 2

DC = BD = 2

DC = 2

This can further be explained as illustrated below:

We'll begin by calculating AD. This can be obtained as follow:

Angle A = 30°

Opposite = BD = 2

Hypothenus = AD =?

Sine A = Opposite (BD) /Hypothenus (AD)

Sine 30 = 2 / AD

0.5 = 2 / AD

Cross multiply

0.5 × AD = 2

Divide both side by 0.5

AD = 2 / 0.5

AD = 4

Finally, we shall determine DC. This can be obtained as follow:

Angle A = 30°

Hypothenus = AD = 4

Opposite = DC =?

Sine A = Opposite (DC) /Hypothenus (AD)

Sine 30 = DC / 4

Cross multiply

DC = 4 × Sine 30

DC = 4 × 0.5

DC = 2

Answer:

(8x + 3)²

Step-by-step explanation:

Since our polynomial is 64x² + 48x + 9, we multiply 64x² by 9 to get 64x² × 9 = 576x² since we cannot simplify the expression any further.

Next, we need to find the factors of 576x² that add up to give 48x, these are 24x and 24x.

So the expression is re-written as

64x² + 48x + 9 = 64x² + 24x + 24x + 9

Writing out all the common factors, we have,

64x² + 48x + 9 = 8x × 8x + 3 × 8x + 3 × 8x + 3 × 3

Factorizing we have

64x² + 48x + 9 = 8x(8x + 3) + 3(8x + 3)

64x² + 48x + 9 = (8x + 3)(8x + 3)

64x² + 48x + 9 = (8x + 3)²

Answer:

DC is congruent to CZ

Step-by-step explanation:

We know two angles are congruent so we need to have the side that is included between those angles so we say that

DC is congruent to CZ

Answer:

81 cm ^3

Step-by-step explanation:

The volume of a cone is given by

V = 1/3 pi r^2 h where r is the radius and h is the height

We are given the diameter of 6 so the radius is 1/2 the diameter

r = 1/2 (6) = 3

V = 1/3 pi r^2 h

   = 1/3 ( 3) * (3) ^2 * 9

 = 81 cm ^3

Answer:

Step-by-step explanation:

The formula for arc length is

[tex]AL=\frac{\theta}{360}*\pi d[/tex] where theta is the central angle. We are given the central angle when we are told that the measure of arc EFG is 240 degrees. The diameter is given as 36, so filling in:

[tex]AL=\frac{240}{360}*\pi (36)[/tex] which can be simplified down a bit to

[tex]AL=\frac{2}{3}*\pi (36)[/tex] and a bit more to

[tex]AL=2\pi(12)[/tex] which gives us, finally,

[tex]AL=24\pi[/tex]

Answer:

D. having students write a definition for each term in their own words in their native language

Step-by-step explanation:

In Mr Fischer's mathematics class, we are presented with two categories of learners. Those that are native speakers of English and those who are learners of English.

Both categories of students would show their understanding best in this lesson if they were to write in their own native language.

The native english-speakers would have no issues writing in English, but those who are English learners would have problems communicating their understanding of the lesson in English. So it is best they give their definitions in their native language.

Answer:

Option B, -3/2

Step-by-step explanation:

The line passes through (4,0) and (0,6)

so, the slope will be

(6-0)/(0-4)

= 6/-4

= -3/2

Answered by GAUTHMATH

Answer:

a is the answer parallelogram is a rotational symmetry

In case of Nina:

slope of graph = speed = 48-32/6-4 = 16/2 =8

y-32 =8(x-4)

y-32=8x-32

y=8x

d=8t

at x= 0 i.e at t= 0

d= 0m

In case of Ryan:

slope =speed = 47.5-35=6-4 = 12.5/2 =6.25

y-35=6.25(x-4)

y-35=6.25x-25

y=6.25x+10

d=6.25t+10

at t = 0, d= 10m

RYAN had a head start of 10 m
