Answer:

y-intecept = (0, y -value)

x-intercept = (x-value, 0)

=> y-intecept = (0, 0.4)

=> x-intercept = (0.3, 0)

Answer: sorry we can’t answer whit out the dots on graph

Step-by-step explanation: To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y. ...

To find the x-intercept, set y = 0 \displaystyle y=0 y=0.

To find the y-intercept, set x = 0 \displaystyle x=0 x=0.

Write the quadratic equation whose roots are 4 and 5, and whose leading coefficient is 4.

Umnica [9.8K]

Answer:

Answer: 4x² - 9x + 20 

Step-by-step explanation:

• General quadratic equation:

${ \rm{ {x}^{2} - (sum \: of \: roots)x + (product \: of \: roots) }}$

• sum of roots → 4 + 5 = 9

• product of roots → 4 × 5 = 20

• substitute:

${ \boxed{ \rm{4 {x}^{2} - 9x + 20 }}}$

How do you find an exact value for sin of 40 degrees without using a calculator

Cerrena [4.2K]

Sin 40° + sin 130° + sin 220° + sin 310° = ...
sin 130° = sin 50°;
sin 220° = - sin 40°;
sin 310° = - sin 50°
... = sin 40° + sin 50° - sin 40° - sin 50° = 0
Answer: 0.

How does scale factor affect the change in area?

MrRa [10]

<h3>Answer:</h3>

It squares the amount you scaled it by.

<h3>Step-by-step explanation:</h3>

For example, imagine that you had 2 by 2 square, and then you put it through a scale factor of 2.

Now each side length would be double of what it once was.

But when you multiply the new lengths together, the area would be of 4 times more.

(Original Equation) 2 * 2 = 4

(Scale Factor of 2) 4 * 4 = 16

So when the scale factor is made, the area would be squared to the multiple that you scaled it by.

***A square root is a number times itself.

(eg): 3 * 3 = 9

15 * 15 = 225

9 and 225 would be the square root in these problems.
