HI = 3.9 and HJ = 6.2. Find IJ

Mathematics
1 answer:
Semmy [17]4 years ago

Answer:

Part 1) IJ=2.3\ units

Part 2) HJ=12\ units

Part 3) HJ=0.75\ units

Part 4) IH=4.7\ units

Step-by-step explanation:

Part 1) HI = 3.9 and HJ = 6.2. Find IJ

we have that

I is between H and J

HJ=HI+IJ

substitute the given values and solve for IJ

6.2=3.9+IJ

subtract 3.9 both sides

6.2-3.9=IJ

2.3=IJ

Rewrite

IJ=2.3\ units

Part 2) JI = 25 and HI = 13. Find HJ

we have that

H is between I and J

IJ=IH+HJ

remember that

IH=HI  and IJ=JI

substitute the given values and solve for HJ

25=13+HJ

subtract 13 both sides

25-13=HJ

12=HJ

Rewrite

HJ=12\ units

Part 3) H is the midpoint of IJ and IH = 0.75. Find HJ

we have that

H is between I and J and H is the midpoint  of IJ

so

IJ=IH+HJ

IH=HJ ----> because H is the midpoint

we have

IH=0.75\ units

therefore

HJ=0.75\ units

Part 4) H is the midpoint of IJ and IJ = 9.4. Find IH

we have that

H is between I and J and H is the midpoint  of IJ

so

IJ=IH+HJ -----> equation A

IH=HJ ----> equation B

substitute equation B in equation A

IJ=2(IH)

substitute the given value and solve for IH

9.4=2(IH)

Divide by 2 both sides

IH=4.7\ units

The parallelogram shown below has an area of 24 units2.
Ber [7]

Answer:

9

===================================================

Explanation:

The area of the parallelogram is equal to the base times height. The formula to use is A = b*h. The height and base are always perpendicular to one another.

The base is some unknown variable b. Multiply the base by the height 15 to get 15*b which is equal to the area 135

Therefore, 15*b = 135

Divide both sides by 15 and we isolate b

15b = 135

15b/15 = 135/15

b = 9

So the base is 9

Check:

area = base*height = 9*15 = 135

so the answer is confirmed

side note: we never use the value 17 at all. It is likely put in there as a distraction.

please just give me the answer is homework please help1)vertex 2)axis of symmetry 3)x-intercepts 4)maximum or minimum 5)max/min
aniked [119]

Answer:

See explanations below

Explanation:

Vertex of a graph is the lowest point on the curve. The vertex occurs at (1.75, -2.5)

The axis of symmetry is the point on the x axis of the line that cuts through the minimum point. The axis of symmetry occurs at x = 1.75

x intercept is the point where the curve cuts the x axis. The x intercept occurs at x = 0 and x = 2.5

To get the minimum, we will use the formula;

c - b^2/4a

The equation of the curve is expressed as;

(x-0)(x-2.5)

= x (x-2.5)

= x^2 - 2.5x

a = 1, b = -2.5, c = 0

minimum = 0 - (-2.5)^2/4(1)

minimum = -6.25/4

minimum = -1.5625

Minimum value occurs at the base of the parabola. The minimum value of the function is -2.5

y intercept is the point where the curve cuts the y axis. The y-intercept occurs at y = 0.
