The required distance of object far from 25° and 55° are 103.71feet and 163.88feet respectively.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Given the trigonometry identity;

d=94 secθ.

If the object is sighted at an angle of  25°, then;

d=94 sec25

d = 94 × 1/cos25

d = 94 × 1.1033

d = 103.71feet

If the object is sighted at an angle of  55°, then;

d=94 sec55

d = 94 × 1/cos55

d = 94 × 1.7434

d = 163.88feet

Hence the required distance of object far from 25° and 55° are 103.71feet and 163.88feet respectively.

Charlotte traveled in 414.44 feet during the time when she looks down at her phone and takes her eyes off the road for 4.06 s.

The first step is to convert miles per hour to feet per second.

(69.6 mi/hr)* (5280 feet/mi)*(1 hr/3600 sec) = 102.08 feet/sec

We know that,

Speed = [tex]\frac{Distance}{Time}[/tex]

Here, we have given,

Time = 4.06 s

Speed (feet/sec) = 102.08 feet/sec

We need to find, the distance charlotte traveled in feet during the time when she looks down at her phone and takes her eyes off the road for 4.06 s.

Putting the values in the formula, we get

Distance = Speed x Time

= 102.08 x 4.06

= 414.44 Feet

Hence, charlotte traveled in 414.44 feet during the time when she looks down at her phone and takes her eyes off the road for 4.06 s.

The value of x in the triangle is 100 units.

A right triangle is a triangle that has one of its angles as 90 degrees.

The triangles formed are similar, therefore, they form a ratio or proportion.

Therefore, using similarity principle of triangles,

36 / 60 = 60 / x

cross multiply

36x = 60 × 60

36x = 3600

divide both sides by 36

36x = 3600

36x / 36 = 3600 / 36

x = 100

Therefore, the value of x in the triangle is 100 units.

Step-by-step explanation:

the first suspicion we get from the first terms is that the creation algorithm is a multiplication by 3.

-1/3 × 3 = -1

-1 × 3 = -3

-3 × 3 = -9

then the next term would be

-9 × 3 = -27

and the next

-27 × 3 = -81

and the 7th term, that we have already defined, would be

-81 × 3 = -243

Answer:

The frog will catch the fly after 2 seconds of his jump.

Step-by-step explanation:

It is given that a frog is about to hop from the bank of a creek. The path of the jump can be modeled by the equation h(x) = -x² + 4x + 1, where h(x) is the frog's height above the water and x is the number of seconds since the frog jumped and a fly is cruising at a height of 5 feet above the water.

Now, let us assume that the frog catches the fly that is cruising at a height of 5 feet above the water;

=> h = 5 feet

So, let us put the value of h = 5 for time x;

=> h(x) = -x² + 4x + 1

=> 5 = -x² + 4x + 1

=> x² - 4x - 1 + 5 = 0

=> x² - 4x + 4 = 0

Now, on solving the above equation we get;

=> x² - 4x + 4 = 0

=> x² - (2 + 2)x + 4 = 0

=> x² - 2x - 2x + 4 = 0

=> x (x - 2) - 2 (x - 2) = 0

=> (x - 2) (x - 2) = 0

On comparing and solving for the value of x we get;

=> (x - 2) = 0

=> x = 2

and

=> (x - 2) = 0

=> x = 2

Therefore, the frog will catch the fly after 2 seconds of his jump.

Inequalities are used to represent expressions that do not have equal values i.e. unequal expression

The word problem is given as

Half of 7 added to product of h and 4 is at least 1

At least 1 means greater than or equal to 1

So, the word problem becomes

Half of 7 added to product of h and 4 is at least 1 ⇒ Half of 7 added to product of h and 4 >=  1

The product of h and 4 means 4h

The product is 6p⁷ - 2p⁵ - 12⁶ + 4p⁴.

We are provided with expressions in three brackets. Performing multiplication between first two brackets first. This will be followed by multiplication of the product of first two brackets with the expression of third bracket.

For multiplication, the rule of exponents to be used is -

aᵇ×aⁿ = aᵇ⁺ⁿ

Rewriting the expression

Product = (p³)(2p² - 4p) (3p² - 1)

Performing multiplication of first two brackets -

Product = (p³ × 2p² - p³ × 4p) (3p² - 1)

Product = (2p⁵ - 4p⁴) (3p² - 1)

Further performing multiplication of product with third bracket -

Product = (2p⁵ × 3p² - 2p⁵ × 1 - 4p⁴ × 3p² - 4p⁴ × - 1)

The line of the graph is a solid line and the region to be shaded depends on the type of the inequality

The graph represents the given parameter

On the graph, we have a straight continuous line

A straight continuous line is an illustration of a solid line

This means that the line of the graph is a solid line

Hence, the line of the graph is a solid line

The graph represents the given parameter

On the graph, we can see that no region of the graph is shaded

This means that the shaded region would be determined by the type of the inequality

It follows that the least integer greater than log√₇ √50 is 3.

We have a logarithm function that is given to us.

Let x = log√₇ √50

We get that:√ 7 ˣ = √ 50

So, we must find an integer x, such that √ 7 ˣ > √ 50.

We know that √ 49 = 7

√ 7 ˣ > 7

7 ⁰°⁵ˣ  > √ 7

x / 2 > 1

x > 2

In this case, x = 3 will be the least integer to satisfy this inequality.

Therefore, it follows that the least integer greater than log√₇ √50 is 3.

Given that  ∠ABC and ∠DEF are supplementary, the numerical value of ∠ABC and ∠DEF are 68° and 112° respectively.

Supplementary angles are angles that sum up to 180 degrees.

Given the data in the question;

Since ∠ABC and ∠DEF are supplementary, it means they sum up to 180 degrees.

Measure of ∠ABC + Measure of ∠DEF = 180°

Plug in the given values and solve for x

(6x + 8) + (12x − 8) = 180

6x + 8 + 12x − 8 = 180

6x + 12x + 8 - 8 = 180

18x + 0 = 180

18x = 180

x = 180/18

x = 10

Now, the numerical measure of each angle will be;

Measure of ∠ABC = (6x + 8)° = 6(10) + 8 = 60 + 8 = 68°

Measure of ∠DEF = (12x − 8)° = 12(10) - 8 = 120 - 8 = 112°

x = 13/2 is not an extraneous solution.

Adding 3 on both the sides of the equation, we get

[tex](2x+3)^{3/4}[/tex] - 3 + 3= 5 + 3

[tex](2x+3)^{3/4}[/tex] = 8

On the right hand side of the equation, 8 can also be written as

[tex](2x+3)^{3/4} = 2^{(3/4)*4}[/tex]

2x + 3 = 16

2x = 13

x = 13/2
