Answer:

h = 5.488 in

Step-by-step explanation:

The area (A) of a parallelogram is calculated as

A = bh ( b is the base and h the perpendicular height )

If we consider the base as 9.8 and h as 5.6 then

A = 9.8 × 5.6 = 54.88 in²

If we consider the base as 10 with perpendicular height h then

10h = 54.88 ( divide both sides by 10 )

h = 5.488 in

In 7th grade there are 58 students with red-hair and 609 students with another color hair. The numbers of red-haired students in

mr_godi [17]

In 7th grade:

red-hair students =58

another color hair students =609

In 8th grade:

red-hair students =60

Let's assume

another color hair students =x

now, we are given

The numbers of red-haired students in 8th grade are proportional to the numbers in 7th

so,

$\frac{60}{58} =\frac{x}{609}$

now, we can solve for x

we get

$x=609*\frac{60}{58}$

we get

$x=630$

so, students have another color hair in 8th grade is 630.........Answer

Select the quadratic function with a graph that has the following features. x-intercept at (8,0) y-intercept at (0,-32) maximum

Basile [38]

Answer:

The correct option is C.

Step-by-step explanation:

The function has axis of symmetry at $x=6$ , it represents that the parabola is along the x-axis and the standard form of parabola is

$y=a(x-h)^2+k$

Where, a is scale factor and (h,k) is vertex.

The maximum or minimum value of a quadratic function is the vertex of parabola. So, vertex of parabola is (6,4).

$y=a(x-6)^2+4$

The y-intercept of the function is (0,-32)

$-32=a(0-6)^2+4$

$-32-4=36a$

$-36=36a$

$a=-1$

Therefore required equation of parabola is

$y=-(x-6)^2+4$

$y=-(x^2-12x+36)+4$

$y=-x^2+12x-36+4$

$y=-x^2+12x-32$

Therefore option C is correct.

Find the area of the polygon.

Allushta [10]

Answer

the area is 26 cm

Step-by-step explanation:

for the first part well call it box C box c is 2 cm by 1 cm the area of that box is 2 because 2 x 1 =2

for box B which is 2 cm by 6 cm because you add the 3 on the bottom to the 3 on the top so box B = 12

for box A it is 3 by 4 so that would be 12

you add the results together 12+12+2=26cm
