Answer:

The y intercept is 1

Step-by-step explanation:

The slope intercept form of a line is

y = mx+b where m is the slope and b is the y intercept

y = 2x+b

Substitute the point into the equation and solve for y

3 = 2(1)+b

3 =2+b

1 = b

The y intercept is 1

If I have 4 A’s and 1 B, what is my GPA?

svetoff [14.1K]

Answer:

3.8

Step-by-step explanation:

Hey! Let's start by assuming that these are all normal courses, and that GPA is given by the following scale:

A - 4.0

B - 3.0

C - 2.0

D - 1.0

F - 0.0

That said, this question really just involves calculating the averages.

To find the average, we add all the values together and divide the sum by the total number of values.

Therefore, our expression would look like:

(4.0 + 4.0 + 4.0 + 4.0 + 3.0)/5

This is because there are 5 total values.

Simplify:

19/5

3.8

This means your GPA would be 3.8

Look for a pattern and complete the conjecture.

denis-greek [22]

Answer:

390

Step-by-step explanation:

The formula of sum of arithmetic sequence is $\frac{n}{2} (a+Tn)$

The number of this series are 2, 4, 6, 8, 10, 12, . . . . , 60.

The first term ( a ) = 2

The 30th even number is 60

The Tn is the term of the sequence

So the equation is

30/2 x ( 2 + $T_{30}$ )

$T_{30}$ = 60

30/2 x ( 2 + 60 )

30/2 x (62)

1860/2

Given: ABCD trapezoid BC=1.2m, AD=1.8m AB=1.5m, CD=1.2m AB∩CD=K Find: BK and CK

stepladder [879]

Answer:

The value of BK is 3m and the value of CK is 2.4m.

Step-by-step explanation:

Given information: ABCD trapezoid

, BC=1.2m, AD=1.8m

, AB=1.5m, CD=1.2m

, AB∩CD=K.

Using the given information draw a figure.

Two sides of a trapezoid are parallel.

Since AB∩CD=K, therefore AB and CD are not parallel, because parallel line never intersect.

$AD\parallelBC$

$\angle KBC=\angle KAD$ (Corresponding angles)

$\angle KCB=\angle KDA$ (Corresponding angles)

By AA rule of similarity

$\triangle KBC\sim \triangle KAD$

Corresponding sides of similar triangles are proportional.

$\frac{KB}{KA}=\frac{KC}{KD}=\frac{BC}{AD}$

$\frac{x}{x+1.5}=\frac{y}{y+1.2}=\frac{1.2}{1.8}$

$\frac{x}{x+1.5}=\frac{1.2}{1.8}$

$\frac{x}{x+1.5}=\frac{2}{3}$

$3x=2x+3$

$x=3$

The length of BK is 3 m.

$\frac{y}{y+1.2}=\frac{1.2}{1.8}$

$\frac{y}{y+1.2}=\frac{2}{3}$

$3y=2y+2.4$

$y=2.4$

The length of CK is 2.4 m.
