The calculated value of the gcf of 64 and 144 is 16

From the question, we have the following parameters that can be used in our computation:

Expressions = 64 and 144

Expand both expressions

So, we have

64 = 2 * 2 * 2 * 2 * 2 * 2

144 = 2 * 2 * 2 * 2 * 3 * 3

Multiply the common factors

GCF = 2 * 2 * 2 * 2

Evaluate

GCF = 16

Hence, the gcf of 64 and 144 is 16

Answer:

its postulate, and theorem

Step-by-step explanation:

i did this assignment

The types of statement can be used to explain the steps of a proof is postulate and theorem.

A statement that has been proven true or that can be proven is known as a theorem in mathematics. A logical argument is used to prove a theorem by using the deductive system's inference rules to show that the theorem follows logically from the axioms and other theorems that have already been proven.

Guessing and Conjecture is just striking some ideas without any definite conclusion.

A claim that is accepted as true without evidence, also referred to as an axiom. Lemmas and theorems are deduced from postulates, which serve as their fundamental building block.

Thus, the statement used in proof is Postulate or Theorem.

Answer:

B - 43

Step-by-step explanation:

The required measure of the angle m∠BDC is 43°.

Given that,

In the diagram, point O is the center of the circle, and m∠ADB = 43°. If m∠AOB = m∠BOC, what is m∠BDC is to be determined.

The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by

(x - h)² + (y - k)² = r²

where h, k is the coordinate of the center of the circle on the coordinate plane and r is the radius of the circle.

Property of circle -
                   "The angle subtended by an arc of the circle to the center point of the circle is double the angle subtended by the same arc on any point the circumference of the circle."

So,
From the above property,
Angle subtended by Arc AB at center or m∠AOB is 2 * 43 = 86°
From given  m∠AOB = m∠BOC,
Implies
m∠BOC = 86°
Angel subtended by arc BC at D is m∠BDC = m∠BOC /2
                                                                         = 86 /2
                                                                         = 43°

Thus, the required measure of the angle m∠BDC is 43°.

Answer:

A coordinate plane showing Falling Leaf, Time in seconds on the x-axis and Height in feet on the y-axis. A line is passing through (0, 12), (8, 10), and (16, 8).

Step-by-step explanation:

The y-intercept of the graph is the height of the leaf at the beginning, that is, 12 ft. This means that point (0, 12) is on the line.

The leaf falls to the ground at a rate of 0.25 feet per second, this means that after 8 seconds, the leaf travel 8*0.25 = 2 ft. Given that it started at 12 ft, its height is 12 - 2 = 10 ft. In other words, the point (8, 10) is on the line. Similarly, its height after 16 seconds is 12 - 16*0.25 = 8 ft, that is, the point (16, 8) is on the line.

Answer:

Luke's kite is 306.4 feet high above the ground

Step-by-step explanation:

To find the height of Luke's kite above the ground, we will follow the steps below:

We can solve the problem using trigonometric ratio;

that is;

SOH CAH TOA

sinФ = opposite/hypotenuse

cosФ= adjacent/hypotenuse

tanФ=opposite/adjacent

From the diagram below:

opposite = x   where x represents the height of Luke's kite above the ground

hypotenuse = 400

Ф = 50

The best trig ratio to use is sin

sinФ = opposite / hypotenuse

sin 50° = [tex]\frac{X}{400}[/tex]

cross-multiply

x = 400 sin 50°

x≈306 .4 feet

Luke's kite is 306.4 feet high above the ground

Answer:

y=x

Step-by-step explanation:

slope intercept form:

y= mx +c, where m is the gradient and c is the y-intercept.

Let's rewrite the given equation in the form of y=mx+c, so that we can determine the gradient of the line.

y-4= x-6

y= x -6 +4

y= x -2

Thus, the gradient of the given line is 1.

the product of the gradients of perpendicular lines is -1.

(gradient of line)(1)= -1

gradient of line= 1

Thus, m=1.

y= 1x +c

y= x +c

To find c, substitute a coordinate.

When x= -2, y= -2,

-2= -2 +c

c= -2 +2

c=0.

Thus the equation of the line is y=x.

Answer:

y = (1/2)x - 3

Step-by-step explanation:

slope-intercept form: y =mx + b

m - slope,

b - y - intercept.

m = 1/2

b= - 3

y = (1/2)x - 3

Answer:

√95 cm

Step-by-step explanation:

To solve, you need to use the pythagorean theorem, or a^2 + b^2 = c^2

The hypotenuse is the c and let one leg be b. You can write:

a^2 + 7^2 = 12^2

a^2 + 49 = 144

Now, you need to solve for a:

a^2 = 144 - 49

a^2 = 95

a = √95 cm, or about 9.75cm

Answer:

Answer:

x ≥ 4

Step-by-step explanation:

There is a closed circle at 4 so it means equals

The line goes to the right so that means greater

x ≥ 4

Answer:

D or x≥4

Step-by-step explanation:

The number has to be 4, since the dot lies on it, so that excludes A and B.

It is greater, because the arrow is pointing right instead of left.

Since the circle is closed, then it means that it includes 4.

So, C would not be the answer, because it is read as " x is greater than 4"

it should be D, which is " x is greater than or equal to 4" (since the circle is closed).

Thus, D is the answer

Angle COD is 60 degrees

angle BOC is 80 degrees

Because angle DOE is vertically opposite to angle boa, it is also 40 degrees. we know that angle DOF is 120, so angle FOE is 120-40 = 80 degree, and angle BOC is vertically opposite do it is 80 degrees.

since angle COD lies on a straight line it adds up to 180 degrees, so 180- 120 = 60 degrees

Solution,

5(t+2)-3(2t+1)=-2

Q) WHICH FORMULA SHOULD BE USED TO CALCULATE VARIANCE?

ANSWER)

We know that there are 2 types of variance, Population variance and sample variance. As in this question, we are considering all the values of the data to find variance. we'll find Population Variance. If we would considered only some values (sample) from the data (population), we would have considered to find sample variance.

Population Variance is given as sigma squared which is calculated by sum of square variables minus mean, divided by number of observation in population.

Step-by-step explanation:

When there is one x-intercept, the discriminant is zero.

__

The discriminant is used to compute the difference between the roots. When it is positive, the real roots are different, so there are two x-intercepts.

When the discriminant is zero, there is no difference between the roots, so there is one x-intercept (as here).

When the discriminant is negative, there are no x-intercepts and the two roots are complex.
