Answer:

For the first triangle the missing sides are 7 and 7√2 For the second triangle,the missing sides are 13√3 and 13

Step-by-step explanation:

For the first triangle,

cos(45°)=7/hypotenuse

hypotenuse×cos45=7

hypotenuse×√2/2=7

hypotenuse=14/√2=7√2

We can now find the adjacent side using Pythagorean theorem,

√(7√2)²-7²=7

For the second triangle,

cos(30°)=adjacent/hypotenuse

but cos 30=√3/2

√3/2=adjacent/26(cross multiply and simplify)

26√3/2=13√3

To find the opposite length,

√(26)²-(13√3)²=13

Answer:

Answer:

4 hours

Step-by-step explanation:

The distances and average speeds for the first two days driven are show below.

Step 1

We calculate the total distance covered in the first two days

First day: 6 hours at an average speed of 60 miles per hour

Hence:

1 hour = 60 miles

6 hours = x

x = 60 × 6

x = 360 miles

Second day: 4 hours at an average speed of 65 miles per hour

Hence:

1 hour = 65 miles

4 hours = x

x = 65 × 4

x = 260 miles

The distance covered for the first two days =

(360 + 260)miles

= 620 miles

Step 2

The total distance for the entire trip = 820 miles

Hence, the distance left to cover on the third day = (820 - 620)miles

= 200 miles

In the question, we are told:

If the average speed on the third day is 50 miles per hour,

The number of hours it will take for them to reach their family friends home is calculated using the formula

Time = Distance/Speed

Time = 200 miles/50 miles per hour

Time = 4 hours

Step-by-step explanation:

Answer:

if ∠1 = 70°, then ∠5= 70°

Hence, option (A) is correct.

Step-by-step explanation:

Given

∠1 = 70°

To determine

We need to determine angle ∠5

From the diagram, it is clear that a transversal line crosses the two parallel lines, the angles in the matching corner would be corresponding angles.

As angle ∠5 is the corresponding angle of angle ∠1 = 70°.

Therefore,

if ∠1 = 70°, then ∠5= 70°

Hence, option (A) is correct.

Answer:

a=9

Step-by-step explanation:

a^2+b^2=c^2

a^2+5.6^2=10.6^2

a^2+ 31.36=112.36

-31.36           -31.36

a^2=81

a=[tex]\sqrt{81}[/tex]

a=9

Answer:

9in

Step-by-step explanation:

is a right triangle so you can use Pythagorean Th.

(10.6)²= (5.6)² + a², subtract (5.6)² from both sides

(10.6)²- (5.6)² =  a²

81 =a², squareroot both sides

√81= √a²

±9 = a we only consider the positive solution because we use it for measurements so a=9

Answer:

14.49

Step-by-step explanation:

14 + 0.49 = 14.49

Answer:

f(-3) = -16

Step-by-step explanation:

Given piecewise function is,

f(x) = 5x - 1       If x < -2

        x + 3       If x ≥ -2

We have to find the value of he function when x = -3

Since x = -3 is less than x = -2,

Piece of the function to be considered,

f(x) = 5x - 1

f(-3) = 5(-3) - 1

f(-3) = -16

Answer:

y = -6/5x + 3

Step-by-step explanation:

y = mx + c (or b, depending on where you're from)

Slope = m = -6/5

y = -6/5x + c

You can sub (0, 3) and (5, -3) into y = -6/5x + c and they both have the same answer where c = 3

Therefore, the equation is y = -6/5x + 3

C. The rate at which the account is increasing

Step-by-step explanation:

The given parameters are;

The rate at which the compound interest on the savings account is compounded = quarterly

The expression given by her banker to find the amount in the account after t years = 4,200(1.05)^(4t)

Therefore, the 1.05 = The rate at which the account is increasing

Answer:

side xy

Step-by-step explanation:

the shortest side is across from the smallest angle.

using the fact that all angles in a triangle add up to 180 degrees, we can figure out that angle z is 30 degrees

therefore, the opposite side from the smallest angle (angle z) is xy

It helps if you draw the triangle out or try to visualize it

Answer:

x=143

Step-by-step explanation:

deNew image over pre-image so 52/4 would equal x/11 because those sides correspond, then cross multiply to get 572 equals 4x then divide each side by 4 to get x=143

Answer:

A

Step-by-step explanation:

Answer:

The answer would be A

Step-by-step explanation:

Use the formula for |A| <= B which is: -B <= A <= B

For this example you would do:

1. Insert the numbers into the formula: -6 <= 2x - 8 <= 6

2. first do the math for -6 <= 2x-8 which is 1 <= x

3. then do the math for 2x - 8 <= 6 which is x <= 7

4. Put that together and you get 1 <= x <= 7

Answer:

Zoey is -362 meters from sea level.  She travels another -71 meters (notice the negative because she is now further away from sea level).  She is now -433 meters from sea level.

Step-by-step explanation:

-362 (original elevation) + -71 (distance to new location) = -433 (total elevation)

Answer:

-433

Step-by-step explanation:

Zoey is already 362 below sea level.

Then she descends another 71 meters

So. . .

-362 - 71

This can also be written as -362 + (-71)

-433
