Question 1 (25 points)
An isosceles triangle has a base 8.8 units long. If the congruent side lengths have measures to the first decimal place, what is
the shortest possible length of the sides?
4.5
8.9
4.3
Od
17.7
b
С

Answers

Answer:

4.5

Step-by-step explanation:

For any triangle, the basic principle for these types of problems is that the sum of the 2 shorter sides has to be greater than the longest side, otherwise it is not a triangle, even if it's equal to the longest side.

So, let's look at the first option. 4.5. Since this is an isosceles triangle and the base is 8.8 units, the other side has to be 4.5 as well. 4.5+4.5=9. 9 > 8.8. So, we can immediately eliminate options 8.9 and 17.7. What about 4.3? Well, 4.3+4.3= 8.6, but 8.6 < 8.8, so 8.6 is wrong. So, the answer is 4.5.

Some number subtracted by -6 is 41. Multiply this number by-3. Then divide
this number by -4. What is the final number?

Answers

Answer:

The final number is 26.25.

Step-by-step explanation:

First, solve the beginning sentence.

"Some number" can be represented by x

x - (-6) = 41    

x + 6 = 41

x = 35

Next, solve the second sentence

35*(-3) = -105

Finally, the last sentence

(-105)/(-4) = 26.25

Calculate the length AB

Answers

Answer:

14.004m

Step-by-step explanation:

Using the SOH CAH TOA trigonometry identity

Tan theta = opposite/adjacent

Given

AB = opposite

BC = adjacent = 20cm

theta = 35 degrees

Substitute

tan 35 = AB/20

AB = 20tan35

AB = 20(0.7002)

AB = 14.004cm

Hence the length of AB is 14.004m

Step-by-step explanation:

Hope this helps

Answer:

0.80 and 1.30

Step-by-step explanation:

0.80, 1.05, 1.30, 1.55, 1.80, 2.05

... + 0.25 = 1.05

= 1.05 - 0.25

= 0.80

0.80 + 0.25 = 1.05

1.05 + 0.25 = 1.30

1.30 + 0.25 = 1.55

1.55 + 0.25 = 1.80

1.80 + 0.25 = 2.05

Step-by-step explanation:

Slope formula is Δy/Δx or (change in y)/ (change in x).

Apply that formula:

You know that 1-(-1) = 2, therefore for a slope of 1/5, the only possibile denominator is 10: 2/10 simplifies to 1/5.

Solve y = f (x) for x. Then find the input when the output is -3.
f(x) = 3x+5

Answers

Answer:

f(-3)= -4

Step-by-step explanation:

Given function in the question is,

f(x) = 3x + 5

Here, values of 'x' are the input values of the function.

And the values of the function f(x) by substituting the values of 'x' are the output values.

If the output value of the function 'f' is -3,

-3 = 3x + 5

3x = -3 - 5

x = [tex]-\frac{8}{3}[/tex]

Therefore, for the input value x = [tex]-\frac{8}{3}[/tex], output value of the function will be f(x) = -3.

I'm really struggling with this problem can someone please give me an examples like this problem or explain how to solve it an problems like it.

Answers

Answer:

Step-by-step explanation:

Ok so I'm not 100% sure how to solve this but what I would do is use the equation a^2 + b^2 = c^2 this equation is used to solve for the hypotenuse or the longest side of a triangle. To find a^2 you would do (21+15)^2 (Also this symbol ^ is the power symbol) and the answer would be 1296. b^2 would be 25^2 or 625. The equation turns out to be 1296 + 625 = c^2. c^2 (or x in this case) would be 1921. To find just c and not c^2 you would find the square root of 1921 which is 43.8292140016 or if rounded would be 43.8. Also this might not help if I misinterpreted the question...
