☆ The relation between x and y is <u>y</u><u> </u><u>=</u><u> </u><u>a</u><u> </u><u>cos</u><u> </u><u>x°</u><u> </u><u>+</u><u>b</u><u> </u>
Taking 1st condition from the table .
→ x = 0 and y = 9
→ y = a + cos 0° + b
→ 9 = a + cos 0° + b
☆ We know that cos 0° = 1
→ 9 = a(1) + b
<h3>→ a + b = 9. equation 1st </h3>
Now taking other condition
→ x = 90° and y = 1
→ y = a cos 90° + b
→ 1 = a cos 90° + b
☆ We know that cos 90° is 0
→ 1 = a(0) + b
<h3>→ 1 = b </h3>
<u>Putt</u><u>ing</u><u> the</u><u> </u><u>val</u><u>ue</u><u> of</u><u> </u><u>b</u><u> </u><u>in</u><u> </u><u>equation</u><u> </u><u>1</u><u>s</u><u>t</u><u> </u><u>.</u><u> </u>
→ 9 = a + 1
→ <u>a</u><u> </u><u>=</u><u> </u><u>8</u><u> </u><u>.</u><u> </u>
<u>Now</u><u> </u><u>taki</u><u>ng</u><u> the</u><u> </u><u>value</u><u> </u><u>of</u><u> </u><u>x</u><u> </u><u>acc</u><u>ording</u><u> to</u><u> the</u><u> </u><u>ques</u><u>tion</u><u> </u><u>.</u>
☆ x = 45 °
→ y = 8 ( cos 45°) + 1
☆ We know that cos 45° is 1/√2
→ y = 8(1/√2) + 1
→ 8 = 4×√2×√2
<h3>y = 4√2 +1 </h3>
So the answer is <u>4</u><u>√</u><u>2</u><u>+</u><u>1</u><u> </u>

Answer:
Therefore,

Step-by-step explanation:
Given:
GF = 12
GE = 16
DF = 12
CF = v
To Find:
v = ?
Solution:
In Δ GFC and Δ GED
∠ E ≅ ∠ F …………..{ measure of each angle is 90° given }
∠ G ≅ ∠ G ……….....{Reflexive Property}
Δ GFC ~ Δ GED ….{Angle-Angle Similarity test}
If two triangles are similar then their sides are in proportion.
On substituting the given values we get

Therefore,

The best design for this study is to do an independent and dependent experiment of the outcomes from different types of soils for tomato plants.
