How many triangles exist with the given side lengths?7 in, 7 in, 7 in

The American antelope (pronghorn) and the wildebeest are among the fastest mammals on the planet, particularly at running long d

Natali5045456 [20]

The antelope is faster than the wildebeest.

Step-by-step explanation:

The maximum recorded speed for the antelope is 88.5 km/h that it can sustain for almost a kilometer.

The equation for distance a wildebeest can run in t hours is given as ;

d=80t

Assume t=1 hour,d=80*1=80 km then you can say the wildebeest takes 1 hour to cover 80 km and 80 km/h

For a distance of 80 km, the antelope will take how many hours;

Time =Distance/speed =80/88.5 =0.904 hours

The antelope takes less hours to cover the distance, hence the antelope is faster than the wildebeest.

A toy is made from a hemisphere, a cylinder and a cone is shown find the total are of a toy

qwelly [4]

Surface area of the cylinder = 2 pi r * 40 = 2 pi * 3* 40 = 24 pi
of the cone this is pi * 3 * 5 = 15pi
of the hemisphere this is 1/2 * 4 * pi * 3^2 = 18pi

So the answer is 24pi + 15pi + 18pi = 57pi = 178.98 cm^2

Please help me on this question.

Katyanochek1 [597]

answer:

A) The angles EA and AG are not congruent.

B) m∠F = 90°

m∠E + m∠F = 180°

90 ° + x = 180° (subtract)

x = 90°

C) Both ∠HEF and ∠AGF are congruent becuase they both have the same angle. Try and measure it using a protractor.

Please help!! i’m stuck and i’ll give brainliest but i need an explanation for the answer

Answer:

-12

Step-by-step explanation:

The average rate of change of a function f(x) on an interval [a, b] is defined as ...

average rate of change = ((f(b) -f(a))/(b -a)

For the given function and interval, this is ...

average rate of change = (f(1.25) -f(0.75))/(1.25 -0.75)

= (4 -10)/(0.5) = -12

The average rate of change is -12 on the interval.

__

The calculator results for f(1.25) and f(0.75) are shown in the attachment, along with the computation of the average rate of change.

The polynomial of degree 4, P(x) has a root of multiplicity 2 at x = 4 and roots of multiplicity 1 at x = 0 and x = - 3 3. It go

NemiM [27]

Answer:

The complete polynomial will be:

$P(x)=\frac{7}{10}x(x+3)(x-4)^2$

Step-by-step explanation:

If one root has multiplicity 2 at x = 4, the factor can write as:

$(x-4)^{2}$ (1)

Now, another root has a multiplicity 1 at x=0 and x=-3, then the factors will be:

$x$ (2)

$(x+3)$ (3)

Putting (1),(2), and (3) together we can construct the polynomial.

$P(x)=Cx(x+3)(x-4)^2$ (4)

C is a constant value

We need to use the point (5, 28) to find the constant C. 5 is the x value and 28 is the P(x) value. Replacing these values into the (4) equation:

$28=C5(5+3)(5-4)^2$

$28=C5(8)(1)^2$

$28=40C$

$C=\frac{28}{40}$

$C=\frac{7}{10}$

Finally, the complete polynomial will be:

$P(x)=\frac{7}{10}x(x+3)(x-4)^4$

I hope it helps you!
