SOMEONE PLS HELP ME FIND THE AREA OF THIS COMPOSITE FIGURE. ILL GIVE BRAINLIEST!

Answers

For this composite question you will need to divide the shape into two different shapes. The large rectangle is going to be 60 in square because of base times height and then you would need to find the square which would be 4 times 4 cause of base times height but because it’s a triable you divide by 3 so 16/2 would be 8 than you would add both shapes and get 68 in squared. Hope that helps!

A rectangular flower garden in Samantha’s backyard has 100 feet around its edge. The width of the garden is 20 feet. What is the length

Answers

Answer:

bces

Step-by-step explanation:

length:30ft

Step-by-step explanation:

if the perimeter is 100 than 20+20+x+x=100.

20+20=40

100-40=60

since there are two length sides, divide 60 by two and then you have your answer.

20+20+30+30=100

PLEASE HELP !!!!!!!! What is the equation of the directrix for the following parabola: -8(x-5)=(y+1)^2

a. y=-3
b. x=7
c. y=7
d. x=-3

Answers

Answer:

x=7

Step-by-step explanation:

The directrix of the equation is x=7

What is directrix of parabola?

The directrix of a parabola is a line that is perpendicular to the axis of the parabola. The directrix of the parabola helps in defining the parabola. A parabola represents the locus of a point which is equidistant from a fixed point called the focus and the fixed line called the directrix. The directrix and the focus are equidistant from the vertex of the parabola. Here we define the directrix for the standard equations of a parabola.

The directrix of the parabola y^2 = 4ax, having x-axis as its axis, passes through (-a, 0), and has the equation x + a = 0.The directrix of the parabola y^2 = -4ax, having x-axis, passes through (a, 0), and has the equation x - a = 0.The directrix of the parabola x^2 = 4ay, having y-axis as its axis, passes through (0, -a), and has the equation y + a = 0.The focus of the parabola x^2 = -4ay, having y-axis as its axis, passes through (0, a), and has the equation y - a = 0.

Given:

-8(x-5)=(y+1)²

Now, using the definition of directrix

x= 8/4 +5

x= 2+ 5

x= 7

List all the possible rational zeros of the function f(x)=x^2-5x+12

Answers

I did not get any zeros since the graph doesn’t cross the x axis, meaning that there are no rational zeros

However, here is the method u can use to find the zeros lol


You can use the quadratic formula in order to get the zeros

This is the equation therefore use these values
ax^2+bx+c=0

A=1
B= -5
C=12

The quadratic formula is -b±√(b^2-4ac))/2a (I left a picture just in case)

1 point for each correct angle measure and 1 point for explaining or showing how you got your answer. Don’t forget to label your answers.

Answers

Answer:

C = 95°

D = 72°

F = 108°

Step-by-step explanation:

Opposite angles of an inscribed quadrilateral are supplementary. Inscribed angles are half the measure of the arc they subtend. (The latter statement can be used to prove the former one.)

Using these relations, we have .

 C = 180° -E = 180° -85° = 95°

 D = 144°/2 = 72°

 F = 180° -D = 180° -72° = 108°

A basketball is thrown upward from a height of 6 feet at an initial speed of 15 feet per second. As the basketball travels, Earth's gravity slows it down.

The height of an object dropped from a height of 6 feet is given by h(t)=−16t2+6.

The distance in feet traveled by an object at a constant speed of 15 feet per second is given by d(t)=15t.

These two functions can be combined to build a new function, f, that models the height of the basketball as a function of time in t seconds.

Which choice shows how to combine h and d to build f

Answers

Answer: f(t)=h(t)+d(t)

f(t)=-16t^2+15t+6

-5 = x

Answer:

x = -5

Step-by-step explanation:

4x - 3 = 6x + 7

Add 3 to both sides to isolate the variable:

4x = 6x + 10

Subtract 6x from both sides to keep x on 1 side:

-2x = 10

Divide by -2 to have the base value of x:

x = -5
