Step-by-step explanation:

f(4)=-3(4)+5 = -12+5=-7

Answer:

No

No

Step-by-step explanation:

In a right angled triangle :

The square of the length of the longest side is equal to the sum of the squares of the two remaining sides : - Pythagoras

That is :

a² = b² + c² (condition must be satisfied).

9m, 4m, 5m

9² = 4² + 5²

81 = 16 + 25

81 ≠ 41 (not right angled)

5cm, 12cm, 14cm

14² = 12² + 5²

196 = 144 + 25

196 ≠ 169 (not right angled)

Answer:

a. 80%

b. £34

c. £340

Step-by-step explanation:

a. We are given that Mrs Trent spent 20% of her weekly wage on food. This means she would have 80% of her weekly wage left with her.

b. 10% of Mrs Trent weekly wage:

If 20% = £68

10% = (10*68)/20 = £34

c. Let x represent weekly wage of Mrs Trent

Given that she spends £68 of x (weekly wage) on food, which is 20% of x.

This means that, 20% of x = £68

Let's find her weekly wage, x:

[tex] \frac{20}{100} * x = 68 [/tex]

[tex] 0.2x = 68 [/tex]

Divide both sides by 0.2

x = 340

Her weekly wage is £340.

Answer:

a) 80%

b) £34

c) £340

Step-by-step explanation:

A -

100% - 20% = 80%

B -

68 = 20%

34 = 10%

c -

34 = 10%

340 = 100%

as you times both sides by 10

Answer:

There's an infinite number of possible answers because there might be any multiplication of 3 for boys and any multiplication of 2 for girls. So, for example:

There might be 3 boys and 2 girls.

There might be 6 boys and 4 girls.

There might be 9 boys and 6 girls.

There might be 12 boys and 8 girls.

etc...

In each case the ratio stays the same - 3 : 2.

Of course there probably can't be more than a few dozens of people in one class, but theoretically we can raise the numbers up to infinite.

The ice cream shop sold small ice creams for $1.25 each and large ice creams for $3.75 each.

This summer the prices will be raised at the same proportion. If x is the new price for small ice creams and y is the new price for large ice creams, then it should be satisfied:

[tex]\frac{1.25}{x}=\frac{3.75}{y}[/tex]

Let's test each option:

A.

[tex]\frac{1.25}{2.50}=0.5[/tex]

[tex]\frac{3.75}{5.00}=0.75[/tex]

B.

[tex]\frac{1.25}{1.50}=0.83[/tex]

[tex]\frac{3.75}{4.50}=0.83[/tex]

C.

[tex]\frac{1.25}{2.00}=0.625[/tex]

[tex]\frac{3.75}{4.25}=0.88[/tex]

D.

[tex]\frac{1.25}{1.80}=0.694[/tex]

[tex]\frac{3.75}{7.20}=0.52[/tex]

Correct choice: B

Step-by-step explanation:

The least to greatest would be 3/10, then 3/8, then 3/6

Answer:

the pairs of corresponding angles are congruent

Step-by-step explanation:

Answer:

Please check the explanation.

Step-by-step explanation:

Given that the measures of the Angles of the triangle ΔXYZ are in the ratio 2:4:6.

Also, the sum of the measure of angles in a triangle is 180°.

so

2x + 4x + 6x = 180

Add similar elements: 2x + 4x + 6x = 12x

12x = 180

Divide both sides by 12

12x/12 = 180/12

Simplify

x = 15

Therefore, the measure of the angles of a triangle will be:

2x = 2(15) = 30

4x = 4(15) = 60

6x = 6(15) = 90

Verification:

30 + 60 + 90 = 180

180 = 180

Answer:

4

Step-by-step explanation:

You want to take the farthest coordinates ( 16/4 ), the closest coordinates to 0 ( 4/1 ), and then subtract to get 12m/3s, then divide 12m by 3s to get 4m/s.

Remember to solve for Slope is SUBTRACTING then dividing.

Answer:

FC = 27, QC = 18

Step-by-step explanation:

The centroid Q is [tex]\frac{1}{3}[/tex] the way along CF , therefore, QF is half as long as CQ

Given FQ = 9, then

QC = 2 × 9 = 18

FC = FQ + QC = 9 + 18 = 27

Answer:

sin²θ

Step-by-step explanation:

Using the trigonometric identities

sin²x + cos²x = 1 ⇒ cos²x = 1 - sin²x

cotx = [tex]\frac{cosx}{sinx}[/tex]

Given

[tex]\frac{1-sin^20}{cot^20}[/tex]

= [tex]\frac{cos^20}{\frac{cos^20}{sin^20} }[/tex]

= cos²θ × [tex]\frac{sin^20}{cos^20}[/tex] ( cancel the cos²θ )

= sin²θ

Step-by-step explanation:

Answer: The height of the palm tree is 21 feet.

Step-by-step explanation:

We can use a ratio to solve this:

Actual height to shadow for both objects. The fraction equivalents must be equal.

6/8 = x/28 . Cross multiply

6(28) = 8x

168 = 8x   Divide both sides by 8  (8's "cancel" on the right)

168/8 =8x/8

21 = x . This gives us the tree's height as 21 feet.

Another way to solve this is to use the ratios, but simplify the first fraction

6/8 = 3/4

Then multiply the length of the shadow by 3/4

3/4 × 28 = height

28÷4 = 7    7 × 3 = 21

21  feet= the height of the palm tree.

Answer:

x² + y² is equal to = (4 / 81)(845m² + 78m + 18)

Step-by-step explanation:

We first need to get the values of x and y, which can be done using a system of equations, substituting one of the two functions into the other:

Given:

y = 2x + 2

3x + 3y = 26m

Then:

3x + 3(2x + 2) = 26m

3x + 6x + 6 = 26m

9x + 6 = 26m

9x = 26m - 6

x = (26m - 6) / 9

Now we can solve for y:

y = 2x + 2

y = 2(26m - 6) / 9 + 2

y = 2(26m - 6) / 9 + 18 / 9

y = (52m - 12 + 18) / 9

y = (52m + 6) / 9

Now we can sum up their squares:

x² + y²

= ((26m - 6) / 9)² + ((52m + 6) / 9)²

= (676m² - 312m + 36) / 81 + (2704m² + 624m + 36) / 81

= (3380m² + 312m + 72) / 81

= (4 / 81)(845m² + 78m + 18)
