HElp mehhhhhh!!! (extra bc it says i didnt write 20 letters)

Explanation:

Imagine that you cross out the top-most square for each step of each diagram. The squares not crossed out have the following counts: 1, 4, 9

This is the sequence of perfect squares. So the rule will have us take the number n, and square it to get n^2. Then we add on the squares we crossed out earlier. This explains the "plus 1" at the end to get the answer of n^2+1

Answer:

7/8 + 4/8 = 1 3/8.

Step-by-step explanation:

In words the answer is 1 and 3/8.

Answer:

1 1/6

Step-by-step explanation:

You can convert 7/6 into a mixed number by subtracting 1 from the improper fraction, because 1= 6/6

7/6 -6/6= 1 1/6

Answer:

7/6 would be 1 1/6

Step-by-step explanation:

To make it a number in general turn into a decimal.

Answer:

One reason, is because it clearer and easier to read.

Seeing two numbers (3^5) can let you know, in this example, 3x3x3x3x3 is harder to understand than 3^5.

3 is the number being multiplied, and 5 tells you how many times.

Answer:

x/-5

Step-by-step explanation:

Just divide by 5 and the denominator will be 5 meaning x would have to be 4.

Make sure your 5 is negative so the whole equation also ends up negative. x/-5=-4/5

Step-by-step explanation:

For first triangle,

sin 45 = 3 / d

1 / root 2 = 3 / d

d = 3 root 2

For second triangle,

tan 60 = 7 / a

root 3 = 7 / a

a = 7 / root 3

Answer:

  obtuse

Step-by-step explanation:

You may remember that side lengths of 3, 4, 5 make a right triangle. Doubling those lengths to 6, 8, 10 will still give a right triangle.

The given triangle has a longest side (11) longer than would be appropriate for a right triangle (10), so the largest angle is larger than 90°.

The triangle is obtuse.

__

Comparison of a triangle to a right triangle with two sides the same is one of several ways the triangle can be classified. You can use the Law of Cosines to find the largest angle, or you can use a triangle solver (as we have below).

In case you don't recall that 3-4-5 makes a right triangle, you can use the Pythagorean theorem to find the longest side of a right triangle with the given shorter sides:

  hypotenuse = √(6² +8²) = √100 = 10

Your long side is longer, so your largest angle is larger than 90°.

Law of Cosines:

  angle = arccos((6² +8² -11²)/(2·6·8)) = arccos(-21/96) ≈ 102.6°

Answer:

[tex]\displaystyle f(x)=\frac{1}{2}x^2-2x-2[/tex]

Step-by-step explanation:

To convert from vertex form to standard form, we can simply expand.

So, we have:

[tex]\displaystyle f(x)=\frac{1}{2}(x-2)^2-4[/tex]

Expand the square:

[tex]\displaystyle f(x)=\frac{1}{2}(x^2-4x+4)-4[/tex]

Distribute:

[tex]\displaystyle f(x)=\frac{1}{2}x^2-2x+2-4[/tex]

Simplify:

[tex]\displaystyle f(x)=\frac{1}{2}x^2-2x-2[/tex]

Answer:

In a general point (x, y) the horizontal component is the x-component, and the vertical component is the y-component.

then if we have the points (a, b) and (c, d)

The vertical distance or change between these points will be the difference between the y-components, and the horizontal distance or change is the difference between the x-components.

Then the vertical change between the points (2.5 , 1) and (5, 2) is:

2 - 1 = 1 unit.

The horizontal change between the points (2.5, 1) and (5, 2) is:

5 - 2.5 = 2.5 units.

Answer:

y = 1

Step-by-step explanation:

To find the y-intercept (s), substitute in 0 for x and solve for y.

y = 2/5 x (0)+1

y-intercepts (0, 1)

Answer:

A=4

Step-by-step explanation:

you use the Pythagorean Theorem,

 a triangle having a Leg b length of 3 and a Hypotenuse c length of 5 would have a Leg a length of 4.

Here is how I solved for Leg a using the Pythagorean Theorem.

Leg a = sqrt[ (Hypotenuse c)2 - (Leg b)2 ]

Leg a = sqrt[ (5)2 - (3)2 ]

Leg a = sqrt[ 25 - 9 ]

Leg a = sqrt[ 16 ]

Leg a = 4

Answer:

8

Step-by-step explanation:

We can use triangle inequality, let AC = x:

x+4 > 5

x+5 > 4

9 > x

Simplifying:

x>1

x>-1

9>x

Thus: 9>x>1

So the Largest whole number is 8
