How to change a quadratic equation into intercept form?

1 answer:

5 0

While most of the ways to write the quadratic equation are redundant and useless, there are three forms that actually have unique uses. These three main forms that we graph parabolas from are called standard form, intercept form and vertex form.

A soccer team estimates that they will score on 77% of the corner kicks. In next week's game, the team hopes to kick 1414 corn

andrezito [222]

Answer:

18.66521%

Step-by-step explanation:

It seems all of the numbers are duplicated, the correct number should be 7%, 14 corner kicks, and 2 opportunities.

The team has 7%(x=0.07) chance to score so that means the chance to not scoring will be: y= 1-x = 100%-7%= 93%. There are 14 opportunities and we want to know the probability to get exactly 2 scores. The calculation will be:

P(x=2)= 2C14 * x^2 * y^12

P(x=2)=91 * 0.07^2 * 0.93^12= 18.66521%

What is the slope of the line for BOTH graphs? Are the slopes the same or different?

Y_Kistochka [10]

Answer:

both are -10

Step-by-step explanation:

x1 y1 x2 y2

1.5 180 6 135

(Y2-Y1) (135)-(180)= -45 ΔY -45

(X2-X1) (6)-(1.5)= 4.5 ΔX 4.5

slope= -10

B= 195

Y =-10X +195

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

x1 y1 x2 y2

1 175 8 105

(Y2-Y1) (105)-(175)= -70 ΔY -70

(X2-X1) (8)-(1)= 7 ΔX 7

slope= -10

B= 185

Y =-10X +185

starting at home, Omar traveled uphill to the gift store for 30 minutes at just 10mph. He then travelled back home along the sam

SashulF [63]

Answer:

average speed for the entire trip is 15 mph

Step-by-step explanation:

Let x be the uphill speed and y be the downhill speed.

We have been given that

Speed of Omar in uphill to reach gift store = x =10 mph

Speed of Omar in downhill to reach his home = y = 30 mph

We know the formula for average speed for the entire trip

$\text{Average speed }=\frac{2xy}{x+y}\\\\=\frac{2\times 10\times 30}{10+30}\\\\=\frac{600}{40}\\\\=15$

Therefore, average speed is 15 mph

Math pls help!! larger number? smaller number?

Georgia [21]

Answer:

larger number = 35

smaller number = 26

Step-by-step explanation:

let larger number be x

and another ( x-9 )

so, x+x-9=61

2x = 70

x = 35

smaller number = 35 - 9

= 26
