The value of x from the figures are 18 and 26 respectively

<h3>Vertical and complementary angles</h3>

13) From the diagram, the angles at the corner is 90 degrees. This shows that the sum of the angles is complementary (sum is 90 degrees)

3x + 2x = 90

5x = 90

x = 90/5

x = 18

15) Since the sum of angles on a straight line is supplementary, hence;

6x + x - 2 = 180

7x = 182

x = 182/7

x = 26

Hence the value of x from the figures are 18 and 26 respectively

Answer:

y = -3x^2 -9x +30

Step-by-step explanation:

When a polynomial has a zero at x=p, it has a factor of (x -p). The factors of your quadratic are ...

f(x) = (x +5)(x -2)

At the point x=3, the value of this product is ...

f(3) = (3 +5)(3 -2) = (8)(1) = 8

In order for that value to be -24, it needs to be multiplied by a scale factor of -3. The quadratic you want is ...

y = -3(x +5)(x -2)

y = -3x^2 -9x +30 . . . . . standard form

Please help and explain <br><br> question 12

il63 [147K]

The sunflower is 2.387 meters tall.

The question is asking: which rounding will result in the greatest value?

To see, we need to round 2.387 to meter, tenth meter, and hundredth meter.

Meter - 2 meters

Tenth meter - 2.4 meters

Hundredth meter - 2.39 meters

As you see, rounding to the tenth meter gives the greatest value of 2.4. Therefore, Bahir should use a decimal rounded to the tenth meter.
