Answer:

f(3) = 113

Step-by-step explanation:

Using the recursive rule and f(1) = 8 , then

f(2) = - 4f(1) + 5 = - 4(8) + 5 = - 32 + 5 = - 27

f(3) = - 4f(2) + 5 = - 4(- 27) + 5 = 108 + 5 = 113

Answer:

11

Step-by-step explanation:

17+9+11+7 divided by 4

because the mean= sum of the terms divided by the number of terms

the sum= 17+9+11+7=44

the number of terms= 4

44 divided by 4= 11

Answer:

(17+9+11+7) / 4 mean is an average

it is equal to the sum of the elements divided by the number of elements

the sum is 44

the number of elements is 4

the mean is the average= 44/4=11

Answer:

The product will always be positive

Step-by-step explanation:

If the base is negative and the exponent is an even number, the final product will always be a positive number. If the base is negative and the exponent is an odd number, the final product will always be a negative number.

Answer:

there is no numbers

Step-by-step explanation:

Answer:

Step-by-step explanation:

Supplementary angles have a sum of 180 degrees.

a+a-27.2=180

2a-27.2=180

2a=207.2

a=103.6, and since b=a-27.2

b=76.4

So one angle is 103.6 degrees and the other is 76.4 degrees.

Answer: The answer is Toni can buy 20 tee shirts for 140 dollars

Step-by-step explanation:

First you find out how many times 5 can go into 20

Next you see that 5 can go into 20, 4 times so you take the 35 and multiply 4 and you get 140 so you can buy 20 tee shirts for 140 dollars.

Answer:

Length = 208in

width=160in

Area=33280in²

Step-by-step explanation:

8ft is equal to 96inches thus ratio is 3:96

length= 6.5×96/3

=208in.

width=5×96/3

=160in.

Area=l×w

=208×206

=33280in²

Answer:

BD = 2.4 units

AB = 4 units

Step-by-step explanation:

using the Pythagorean theorem:

3²-1.8² = BD²

BD² = 5.76

BD =  2.4

2.4²+3.2² = AB²

AB² = 16

AB = 4

This  has to be determined by pythagorian theorem. Hence the value of AB= 4 units and BD= 2.4 units.

Given: AD = 3.2 units

          BC  = 3 units

          CD  = 1.8 units

Find : AB =? units

          BD=? units

As we know that ,

By the formula of  pythagorian theorem,

Let be a ΔABC,

                     [tex]\bold{(AB)^{2} = (BC)^{2} +(AC)^{2}}[/tex]

From the above formula now  determined  the value of AB and BD,

Firstly , find the value of BD

In ΔBDC, by applying pythagaorian theorem,

[tex]\bold{(BC)^{2} = (BD)^{2} +(DC)^{2}}[/tex]                                                         ...(1)

Here, BC  = 3 units and CD = 1.8 units

Now put the values of  BC and CD  in (1),

[tex]\begin{aligned}(3)^{2} &=(BD)^{2}+(1.8)^{2}\\9&=(BD)^{2}+3.24\\9-3.24&=(BD)^{2}\\5.76&=(BD)^{2}\\\sqrt{5.76} &=BD\\\bold{BD&= 2.4}\:units\end{aligned}[/tex]                                                         ...(2)

Now find the value of AB,

In ΔABD, by applying pythagorian theorem,

[tex]\bold{(AB)^{2}=(AD)^{2} + (BD)^{2} }[/tex]                                                       ...(3)

Here, AD=3.2 and from (2) BD=2.4

By putting values in (3) ,

[tex]\begin{aligned}(3.2)^{2} +(2.4)^{2}&=(AB)^{2}\\10.24+5.76&=(AB)^{2}\\16&=(AB)^{2}\\\sqrt{16} &=AB\\\bold{AB&= 4}\:units\end{aligned}[/tex]

Therefore,the values of AB=4 units and BD= 2.4 units.

Step-by-step explanation:

Answer:

a) 5²/4². b) 4.2²/2.8²

This is your answer ☺️☺️

a. [tex]\frac{5}{4}[/tex]

b. [tex]\frac{3}{2}[/tex] or [tex]1\frac{1}{2}[/tex]
