Answer:

8 in²

Step-by-step explanation:

The area of a triangle is always base times half height. Since this triangle has a 90° corner, the vertical 4 inch is also the height.

So area is 4*4/2 = 8

Standard: 784,000

Word: seven hundred eighty-four thousand

Expanded: (700,000) + (80,000) + (4,000)

Answer:

400

Step-by-step explanation:

Answer:

its just 4 because its in the ones place also the comas arent placed correctly

If the commas are placed correctly then it is 400. Pretend there are 2 imaginary zeros after it.

Answer:

Use the slope formula

Points A(a, b) and B(c, d)

Points A(-7, a) and B(c, d)

Answer:

See answers below

Step-by-step explanation:

Given that sin theta = √3/√7

Opposite =√3

Hypotenuse = √7

Get the adjacent

Adj² = (√7)²-(√3)²

Adj² = 7-3

Adj² = 4

Adj = √4

Adj = 2

Cos theta = adj/hyp = 2/√7

csc theta= 1/sin theta = 1/(√3/√7) =

√7/√3

sec theta= 1/costheta = 1/(2/√7) = √7/2

tan theta= opp./adj = √3/2

cot theta =1/tan theta = 1/(√3/2) = 2/√3

= 2√3/3

Answer:

a= 14^2 or 196

Answer:

B - 108

Step-by-step explanation:

A regular pentagon is 540 degrees. Divide 540 by 5 (since there are five sides) which equals 108 degrees.

Answer:

Step-by-step explanation:

Scale factor is the ratio of the corresponding sides:

Find m using the scale factor:

Answer:

scale factor is 4 and m is 16.

Step-by-step explanation:

This is because these are similar rectangles, so the proportion of each side to the congruent side is the same. This means that to get from 7 to 28 u multiply by a scale factor of 4, and to get m you would multiply 4 by 4.

The area under the curve is essentially the definition of an integral.

Step 1: Define

Parametric

x = t

y = 3t²

1 ≤ t ≤ 2

Step 2: Rewrite

Rewrite parametric to rectangular form and change bounds of integration.

Answer:

3, and -3

Step-by-step explanation:

Because absolute value is the distance away from zero, |3| and |-3| would both be 3 units away from 0. Be sure to have the negative on the inside if you're trying to make something positive, otherwise -|3| means that the absolute value of 3 would then become negative since the negative sign isn't a part of the absolute. hope this helps!

The numbers whose absolute values is 3 are : 3 and - 3

The absolute value of a number is the distance from zero a number is on the number line. Absolute values measures the distance from zero ignoring whether the distance is to the right or left of the number line.

Three units to the right of Zero = 3

Three units to left of Zero = -3

The absolute value of - 3 represented as |-3| = 3

Hence, The numbers whose distance from zero is 3 on the number line are : 3 and - 3

Answer:

C) x²-2x-15=0

Step-by-step explanation:

You could put both -3 and 5 in the equations to guess and check, but the better way is to use them to create the factors.  If -3 is a root, one of the factors must be (x+3).  If 5 is a root, the other factor must be (x-5).  

(x+3)(x-5)

x²-5x+3x-15=0

x²-2x-15=0

Answer:

y = -4x-4

Step-by-step explanation:

We need to find an equation of the line that passes through (1,0) and has a slope of m=-4.

The equation of a line is given by :

y = mx+c

Where

m is slope of line

Put all the values,

y = -4x+c

Put x = 1 and y = 0

So,

0 = -4(1)+c

c = -4

So, the required equation is :

y = -4x-4

Answer:

5.16

Step-by-step explanation:

We multiply the number of weeks by the number of days to find the total amount of days that she ran:

5 weeks × 3 days/week = 15 days

We are looking for the amount of miles/day (which represents the number of miles per day).

So, we take [tex]\frac{77.4miles}{15days}[/tex]= 5.16 miles/day
