Can someone Help meeee!!

Answer:

The first 3 terms of the sequence [tex]t(n)=-2n+7[/tex] are:

[tex]5, 3, 1[/tex]

Step-by-step explanation:

Given the sequence

[tex]t(n)=-2n+7[/tex]

Here [tex]n[/tex] represents any term number in the sequence

Determining the first term

substitute n = 1 in the sequence to determine the first term

[tex]t(n)=-2n+7[/tex]

[tex]t(1)=-2(1)+7[/tex]

[tex]t(1)=-2+7[/tex]

[tex]t(1) = 5[/tex]

Determining the 2nd term

substitute n = 2 in the sequence to determine the 2nd term

[tex]t(n)=-2n+7[/tex]

[tex]t(2) = -2(2) + 7[/tex]

[tex]t(2) = -4 + 7[/tex]

[tex]t(2) = 3[/tex]

Determining the 3rd term

substitute n = 3 in the sequence to determine the 3rd term

[tex]t(n)=-2n+7[/tex]

[tex]t(3) = -2(3) + 7[/tex]

[tex]t(3) = -6 + 7[/tex]

[tex]t(3) = 1[/tex]

Therefore, the first 3 terms of the sequence [tex]t(n)=-2n+7[/tex] are:

[tex]5, 3, 1[/tex]

Answer: 15.48 m/s

Step-by-step explanation:

The following information can be gotten from the question:

Total distance covered by the car will be:

= 400m + 250m

= 650m

Total time taken = 18.0s + 24.0s = 42s

Average speed = Distance/Time

= 650/42

= 15.48 m/s

Step-by-step explanation:

r/3 = 18

r/3 * 3 = 18 * 3

r = 54

Answer:

54

Step-by-step explanation:

multiplication is the opposite of division so you can do 18*3=54 and you can check that by dividing 54 and 3 and the answer is 18

Answer:

5.95

Answer: 209

Step-by-step explanation:

Si un número tiene 2 centenas, significa 200. Si tiene 0 decenas, entonces debería haber un 0 en el lugar de las decenas. Si un número tiene 9 unos, entonces debería haber un 9 en el lugar de las unidades. Debido a esto, el número con Número que tiene dos centenas, cero decenas y nueve unidades es 209.

English answer:

If a number has 2 hundreds, it means 200, and there should be a 2 in the hundreds place. If it has 0 tens, then there should be a 0 in the tens place. If a number has 9 ones, then there should be a 9 in the ones place. Because of this, the number with Number that has two hundreds, zero tens, and nine ones is 209.

Answer:

-3,2,2,5,34

Step-by-step explanation:

Answer:-3,2,2,5,34

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given the sum of the first n consecutive even numbers expressed as

S=n^2+n where n ≥ 2.

If S  = 210, then;

210 = n² + n

n² + n - 210  = 0

Factorize

n = -1±√1²-4(-210)/2

n = -1±√1+840/2

n = -1±√841/2

n = -1±29/2

n = -1+29/2 and -1-29/2

n = 28/2 and -30/2

n = 14 and -15

Since n ≥ 2, hence the required value of n is 14

Answer:

The additional roots are: [tex]5 - 12i[/tex] and [tex]-9 + 7i[/tex]

Step-by-step explanation:

Given

Roots: [tex]5 + 12i[/tex] and [tex]-9 -7i[/tex]

Required

Determine two additional roots

For a polynomial with two rational roots, the additional roots are the conjugates of the roots.

Take for instance, the following expression:

[tex]a + \sqrt b[/tex]

The conjugate of [tex]a + \sqrt b[/tex] is: [tex]a - \sqrt b[/tex].

Having established how to determine the additional roots, we proceed to determine the roots.

The conjugate of [tex]5 + 12i[/tex] is [tex]5 - 12i[/tex] and the conjugate of [tex]-9 -7i[/tex] is [tex]-9 + 7i[/tex]

Hence, the additional roots are: [tex]5 - 12i[/tex] and [tex]-9 + 7i[/tex]

Step-by-step explanation:

9(x+1)=25+x

x=16/8

x=2

Answer: 3

Step-by-step explanation:

6y, 4y, and 2a

Answer:

y = 8

x = 17

Step-by-step explanation:

We can find the missing values using similarity ratio

15/30 = y/16 cross multiply expressions

30y = 240 divide both sides by 30

y = 8

Now do the same for x

15/30 = x/34 cross multiply expressions

30x = 510 divide both sides by 30

x = 17

vertical angles and right angles in a quadrilateral

Answer:

k = 13

Step-by-step explanation:

If (x-1) is a factor, then f(1) = 0

4*1 + k*1 - 7*1 - 10 = 0

4 + k  - 7 - 10 = 0

      k - 13     = 0

                k = 13

Answer:

a. f(x)=58-5(x-1); there are 58 boxes in the top row.

b. 273 boxes

Step-by-step explanation:

There are 33 boxes at the bottom row, and there are 5 fewer boxes than the row before it meaning that each row above the bottom row has five more boxes than the one below it.

Basically:

bottom row (with 33 boxes) -->5th row-->4th row-->3rd row-->2nd row-->1st row

each arrow adds five boxes, so if you add 5 boxes for each arrow, there is a total of 58 boxes on the 1st row.

check:

2nd row:

f(x)=58-5(x-1)

f(2)=58-5(2-1)

f(2)=58-5(1)

f(2)=58-5

f(2)=53

and we know that 58 (first row)-5=53 (second row; has to have five fewer boxes) so the function works.

now we can use the formula to find the other row values:

3rd row:

f(x)=58-5(x-1)

f(3)=58-5(3-1)

f(3)=58-5(2)

f(3)=58-10

f(3)=48

4th row:

f(x)=58-5(x-1)

f(4)=58-5(4-1)

f(4)=58-5(3)

f(4)=58-15

f(4)=43

5th row:

f(x)=58-5(x-1)

f(5)=58-5(5-1)

f(5)=58-5(4)

f(5)=58-20

f(5)=38

so, we have the row values from top to bottom:

58, 53, 48, 43, 38, 33

now we just have to add them up, giving us 273 boxes in total.
