Tracy wants to determine the coordinates of the minimum value of a quadratic function. She
writes the equation for the function in different forms.
Which form of the function would be MOST helpful to determine the coordinates of the
minimum value? *

O y = (x + 1)2 - 25
O y = x² + 2x - 24
O y = 2(x - 12) + x?
O y = (x - 4) (x + 6)

Answers

The most helpful form to find the coordinates of the minimum is the vertex form.

Which form is better to find the minimum?

Remember that for a quadratic equation with a positive leading coefficient, the minimum is at the vertex.

So the better form to determinate the coordinates of the minimum value will be the vertex form, where if the vertex is (h, k), we get:

y = a*(x - h)^2 + k

In this case, the first option is in that form:

y = (x + 1)^2 - 25

so:

h = -1

k = -25

This means that the coordinates of the minimum are (-1, -25)

1. Trey just planted a small tree. He wanted to help it grow straight so he anchored the tree to the ground in three places using equal lengths of wire. The wires are tied to the tree 8 feet above the base of the tree. If Trey anchored each wire to the ground 6 feet from the base of the tree, what length of wire, in feet, is required for each anchor?

Answers

Answer:The correct answer is:

90 feet.

Explanation:

Each wire forms a right triangle with the tree and the ground. The height from the ground to the point on the tree the wire is attached to, 3 feet, is one leg. The length from the tree to where the wire is staked in the ground, 4 feet, is the other leg.

We use the Pythagorean theorem to find the hypotenuse: 3²+4²=c²; 9+16=c²; 25=c²; √25=√(c²); 5=c

This means each wire will be 5 feet long. There are 3 wires per tree, which gives us 5*3 = 15 feet. There are 6 tree, so this is 15*6 = 90 feet of wire.

A scientist is growing bacteria, starting with a culture of 10 bacteria. The colony of bacteria doubles every 3 hours. Which equation represents the relationship between the number of bacteria (b) and the number of hours (t) that have elapsed?
A) B= 10(2)^t
B) B= 10(2)^t/3
C) B= 10(2)^3t
D) B= 10(e)^2t
E) B= log₂(t)

Answers

Answer:

B) B=10(2)^(t/3)

Step-by-step explanation:

The Formula used to find Exponential Growth is

[tex]y=a*b^{\frac{t}{t_{1} } }[/tex]

where y is the Final Amount

a is the Initial Amount

b is the Growth Factor

t is Time

t1 is Time to Complete one Growth

so for our Problem

a=10 and b=2 and t1=3 and y=B

so B=10(2)^(t/3)

Initial amount of bacteria=10Doubles in every 3 hoursMeans time is t/3

So

The expression is

[tex]\\ \rm\rightarrowtail B=10(2)^{\frac{t}{3}}[/tex]

A and B are two brothers. A weigh 50 kg and B weigh 45 kg. if they divide 285 g of roasted meat in the ratio of their weight, how many grams does each get? ​

Answers

Answer:

Share of A = 150 grams

Share if B = 135 grams

Step-by-step explanation:

Weight of A = 50 kg

Weight of B = 45 kg

ratio of weights = 50 : 45 = 10 : 9

Let the common multiplier of the ratio be x.

-> 10x + 9x = 285

-> 19x = 285

-> x = 285/19

-> x = 15

-> 10x = 150

-> 9x = 135

Share of A = 150 grams

Share if B = 135 grams

The bearing of P from Q is 046º.
The bearing of R from Q is 124º.
QR = QP.
Work out the bearing of R from P.

Answers

Answer:

  175°

Step-by-step explanation:

Bearing angles are usually measured clockwise from North. Reverse bearing angles differ from forward bearing angles by 180°. These relations and the usual angle sum relation for a triangle can be used to solve this problem.

Angle PQR will be the difference in the bearings from Q to P and Q to R:

  ∠PQR = 124° -46° = 78°

Triangle PQR is isosceles, so the base angle at P will be ...

  ∠QPR = (180° -78°)/2 = 51°

__

The bearing from P to R will be 51° less than the bearing from P to Q. The bearing from P to Q is 180° more than the bearing from Q to P.

  PR bearing = PQ bearing - ∠QPR

  = PQ bearing - 51°

  = (46° +180°) -51° = 175°

The bearing of R from P is 175°.

KE is twice as KI.If its perimeter is 42cm, how long is KI?​


please

Answers

Call KE as a, KI as b

To calculate the perimeter of a kite, we use the formula : 2(a+b)

The perimeter is 42cm, hence a + b = 42/2 = 21 cm

Now, we can write the ratio between a and b as 2:1 (because KE is twice as long)

So, we can calculate KI by taking the sum and divide by the total ratio parts

21 : (2 + 1 ) = 7

Recheck : KI = 7 -> KE = 14

Perimeter = (7+14) x 2 = 42, and 14 is indeed 2 x 7.

Answer:

  296.1 yards

Step-by-step explanation:

The surveyor is interested in solving a triangle with two sides and the enclosed angle known. The Law of Cosines is used for that purpose.

The angle interior to the triangle where the surveyor turned is the supplement of the turning angle:

  180° -110° = 70°

The law of cosines tells us the relation of the given sides (a, b) and angle (C) to the unknown side (c) is ...

  c² = a² +b² -2ab·cos(C)

  c² = 245² +270² -2·245·270·cos(70°) ≈ 87675.7350

  c ≈ √87675.7350 ≈ 296.10

The length of the lake is about 296.1 yards.
