A line is given by the equation 9x + 2y = 10. Which equation gives a line perpendicular to this line?

Answer:

1. 23.8

2. 7.7

Step-by-step explanation:

for the first blank

use sin because x is opposite and 25 is hypotenuse

set up an equation:

sin(72)= (x/25)

multiply both sides by 25:

25(sin(72))= (x/25)25

25(sin(72))= x

multiply 25 by sin(72):

23.8 = x

for the second blank

use cos because x is adjacent and 25 us hypotenuse

set up an equation:

cos(72)= (x/25)

multiply both sides by 25:

25(cos(72))= (x/25)25

25(cos(72))= x

multiply 25 by cos(72):

7.7= x

Answer:

[tex]D(x)= x\sqrt{2}[/tex]

Step-by-step explanation:

Given

[tex]Side = x[/tex]

Required

Represent the diagonal as a function

Using Pythagoras theorem, the diagonal is:

[tex]D^2= Side^2 + Side^2[/tex]

Substitute x for Side

[tex]D^2= x^2 + x^2[/tex]

[tex]D^2= 2x^2[/tex]

Take the square root of both sides

[tex]D= \sqrt{2x^2[/tex]

Split

[tex]D= \sqrt{2} * \sqrt{x^2[/tex]

[tex]D= \sqrt{2} * x[/tex]

[tex]D= x\sqrt{2}[/tex]

Express as a function.

[tex]D(x)= x\sqrt{2}[/tex]

Answer:

Step-by-step explanation:

By Pythagoras' Theorem, a² + b² = c².

Substituting the values of a and b, we get:

7² + 25² = c²

49 + 625 = c²

c² = 674

c ≈ 26.0 (to 1 d.p.)

Answer:

z = 17.5

Step-by-step explanation:

To get the value of z, we use the bisector theorem

7/z = 6/15

6z = 7 * 15

6z = 105

z = 105/6

z = 17.5

Answer:

#5) B, C, D

#6) Yes; B, C, and D have lengths greater than one meter. and their areas are exactly one square meter

Step-by-step explanation:

Options B, C and D have an area of 1 square meter and their length is greater than 1 meter and the width is less than 1 meter.

Given that, Danah is planting a second strawberry patch and wants it to have an area of exactly 1 square meter.

To find the area of each different shape strawberry patch, you have to find out which options have an area of 1 square meter.

Area of rectangle formula=Length×Breadth.

From option A:

Area= 1/2 × 3/2=3/4 =0.75 square meters

From option B:

Area= 2/3 × 3/2 =1 square meters

From option C:

Area= 4/5 × 5/4 =1 square meters

From option D:

Area= 2/3 × 6/4=2/2 =1 square meters

Therefore, options B, C and D have an area of 1 square meter and their length is greater than 1 meter and the width is less than 1 meter.
