Evaluate f(t)=-2t2+ 1 for f(-3).

Answers

Answer 1

Answer:

7

Step-by-step explanation:

First, plug-in f(-3) into t in the function:

[tex]f(-3)=-2(-3) +1[/tex]

Second, multiply -2 and -3 to get 6:

[tex]f(-3)=-2(-3)+1[/tex]⇒[tex]f(-3)=6+1[/tex]

Third, add 6 and 1 to get your answer:

[tex]f(-3)= 6+1[/tex]⇒[tex]f(-3)=7[/tex]

If -7.6(x - 1) = 7.3 - 7.4x, find the value of -2x.

Answers

Answer:

-3

Step-by-step explanation:

Step 1: Write equation

-7.6(x - 1) = 7.3 - 7.4x

Step 2: Solve for x

Distribute -7.6: -7.6x + 7.6 = 7.3 - 7.4x

Add 7.6x on both sides: 7.6 = 7.3 + 0.2x

Subtract 7.3 on both sides: 0.3 = 0.2x

Divide both sides by 0.2: x = 1.5

Step 3: Find -2x

-2(1.5) = -3

Answer:

3

Step-by-step explanation:

-7.6x+7.6=7.3-7.4x

-7.6x+7.4x=7.3-7.6

-0.2x=-0.3

X=-0.3/-0.2

X=3/2

What is Algebra?

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem accurately and completely.

At sunrise, the temperature outside was 5°C below zero By noon the temperature rose to 27°C. Then the temperature at noon is given as,

⇒ 27°C + (-5°C)

⇒ 27°C - 5°C

⇒ 22° C

The temperature at noon after a rise of 27°C will be 22°C.

An object is moving at a speed of 6 feet per day. Express this speed in miles per year. Round your answer to the nearest hundreth

Answers

Answer:

.41

Step-by-step explanation:

1ft = 0.000189394mi

0.000189394 x 6mi =0.00113636mi

1 year = 365 days

365 x 0.00113636 =0.41477286

The given speed in miles per year should be 0.41477286.

Given that,

The object speed should be 6 feet per day.

Based on the above information, we know that

1 feet = 0.000189394miles

Now there are 6 feet.

So, for 6 feet, the miles should be  

= 0.000189394 × 6mi

= 0.00113636mi

Now for per year, it should be  

= 365 × 0.00113636

= 0.41477286

Therefore we can conclude that the given speed in miles per year should be 0.41477286.

Write 3 and 3/4 as a decimal. Is it repeating or terminating?

Answers

Answer:

3.75, Terminating

Step-by-step explanation:

To answer this, we simply have to find what 3/4 is as a decimal. So, we know that in order to make 4/4, or 1, we need 4 parts. Let's say that 4/4 would equal 100, so we need to divide 100 into 4 parts:

100 / 4 = 25

Now, to find what 3/4 is, all we have to do is multiply 25 by 3:

25 * 3 = 75

And that is our decimal form, we just need to add the 3:

3.75, and since .75 doesn't keep on repeating, it just stops at .75, this is a terminating decimal

Hope this helps! :)
