Answer:

7. is G

8. f(4)=-120

Step-by-step explanation:

7. les do f(0)=4 since its the easiest

F. f(0)=0.4(0+5)(0-2)

    0.4*-2*5=-4                NOT IT. the ans. is +

G. f(0)=-0.4(0+5)(0-2)

    -0.4*-2*5=4               YESSSSSS

H. f(0)=-0.4(0-5)(0+2)

     -0.4*2*-5=4              YESSSSSS

J. f(0)=0.4(0-5)(0+2)

     0.4*2*-5=-4              NOT ITTTT

so G n H

 Put both equation=0

G. 0=-0.4(x+5)(x-2)

    x=-5,2     YASSSS this is the ans.

WHO EVER ANSWERS FIRST WILL GET A BRAINLY!!!!!!PLS BE QUICK
OLEGan [10]

Step-by-step explanation:

(2$+1.5&)+0.9$X=20$

3.5$+0.9$X=20$

0.9$x=20$-3.5$

x=16.5$/.9$

x=18.333

so he can travel 18.333miles.

first we need to add the two separated cause of 1.5 Dollar in $2 tip which give us 3.5 dollar that is to be subtracted from the $20 you have. then the money that is left in your pocket is 16.5 dollar s this will be deducted 0.9 for every mile so dividing 16.5 by 0.9 gives 18.333.

Find the perimeter. Use 3.14 for pi. Round to the nearest tenth.
MAXImum [283]

Answer:

22cm

See explanation below

Step by step explanation:

The question is incomplete without the diagram of the shape or its dimensions.

From the question, we are to determine the perimeter of the circle.

Let's consider the following question by determining the perimeter of a circle. If diameter is 7cm. Use pi as 3.14.

Perimeter of circle = circumference of circle

circumference of circle = 2πr

Radius = diameter/2 = (7/2)cm

circumference of circle = 2πr

= 2×π×(7/2) = (14/2)×3.14

= 7×3.14

=21.98cm

circumference of circle = 22cm (nearest tenth)

Perimeter of circle = 22cm

36, 27, <br> 81<br> 4<br> Find the 10th term.
zaharov [31]

a_{10} = \frac{177147}{65536} is solution of arithmetic progression (AP).

What is arithmetic progression (AP)  in math?

  • The difference between any two consecutive numbers in an arithmetic progression (AP) is always a fixed amount.
  • The AP cost per invoice is calculated by dividing the total number of invoices paid over a certain time period by all the expenditures incurred to pay those invoices over that same time period.
  • An accurate assessment of a company's AP efficiency can be made using this metric in conjunction with other accounts payable measures.

Write the general term through the pattern a_{n} = 36( \frac{3}{4} )^{n-1}

Substitute and calculate a_{10} = \frac{177147}{65536}

How do I subtract decimals from whole numbers?
Gekata [30.6K]

Answer:

Just use long subtraction by expanding the decimal places of the whole number. This is done by adding a point, and enough zeros to it to match the number of decimal digits in the other number (digits after the decimal point).

12345678

i.e: 5 - 2.48374827, 2.48374827 has 8 decimal digits, so add 8 zeros after the point.

=

1 1 1 1 1 1 1

5.00000000

2.48374827

_______________

2.51625173

7 + 3 = <u>1</u>0, 7 + 2 + <u>1</u> = <u>1</u>0, 8 + 1 + <u>1</u>= <u>1</u>0, 5 + 4 + <u>1</u> = <u>1</u>0, 2 + 7 + <u>1</u> = <u>1</u>0, 3 + 6 + <u>1</u> = <u>1</u>0, 1 + 8 + <u>1</u> = <u>1</u>0, 5 + 4 + <u>1</u> = <u>1</u>0, 2 + 2 + <u>1</u> = <u>5</u><u> </u><u>:</u><u> </u>5.00000000

This is basically borrowing a group of 10s which are the same as 1s in the next decimal place up.

For each digit except the first to the right, let 10 subtract that number from it and minus 1 since the 1 is carried over.
